    NAME
         queue_conf - Grid Engine queue configuration file format

    DESCRIPTION
         Queue_conf reflects the format of the template file for  the
         queue  configuration.   Via  the  -aq and -mq options of the
         qconf(1) command, you can add queues and modify  the  confi-
         guration of any queue in the cluster.

         The queue_conf parameters take as  values  strings,  integer
         decimal  numbers  or  boolean, time and memory specifiers as
         well as comma separated lists. A time specifier either  con-
         sists  of  a  positive decimal, hexadecimal or octal integer
         constant, in which case the value is interpreted  to  be  in
         seconds,  or is built by 3 decimal integer numbers separated
         by colon signs where the first number counts the hours,  the
         second  the  minutes  and the third the seconds. If a number
         would be zero it can be left out but  the  separating  colon
         must remain (e.g. 1:0:1 = 1::1 means 1 hours and 1 second).

         Memory specifiers are positive decimal, hexadecimal or octal
         integer  constants  which  may  be  followed by a multiplier
         letter. Valid multiplier letters are k, K, m and M, where  k
         means multiply the value by 1000, K multiply by 1024, m mul-
         tiply by 1000*1000 and M multiplies by 1024*1024. If no mul-
         tiplier is present, the value is just counted in bytes.

    FORMAT
         The following list of queue_conf  parameters  specifies  the
         queue_conf content:

      qname
         The name of the queue on the  node  (type  string;  template
         default: template).

      hostname
         The fully-qualified host name of the node (type string; tem-
         plate default: host.dom.dom.dom).

      seq_no
         With sort_seq_no  (see  sched_conf(5))  set  to  TRUE,  this
         parameter  specifies this queue's position in the scheduling
         order within the suitable queues for a job to be dispatched.
         It  thus  replaces  the order by load policy that would rule
         otherwise.

         Regardless of  the  sort_seq_no  setting,  qstat(1)  reports
         queue  information  in the order defined by the value of the
         seq_no. Set this parameter  to  a  monotonically  increasing
         sequence. The type is number and the default is 0.

      load_thresholds
         load_thresholds is a list of load thresholds. Already if one
         of  the  thresholds  is  exceeded  no  further  jobs will be
         scheduled to the queues on this node and qmon(1) will signal
         an  overload  condition for this node. Arbitrary load values
         being defined in the "host" and "global" complexes (see com-
         plex(5) for details) can be used.

         The syntax is that of a comma separated list with each  list
         element  consisting  of  the  name of a load value, an equal
         sign and the threshold value being intended to  trigger  the
         overload situation (e.g. load.avg=175,users_logged_in=5).

         Note: Load values as well as  consumable  resources  may  be
         scaled  differently  for different hosts if specified in the
         corresponding   execution   host   definitions   (refer   to
         host_conf(5) for more information). Load thresholds are com-
         pared against the scaled load and consumable values.

      suspend_thresholds
         A list of load thresholds with the same semantics as that of
         the   load_thresholds  parameter  (see  above)  except  that
         exceeding one of the denoted thresholds initiates suspension
         of  one  of  multiple  jobs  in the queue.  See the nsuspend
         parameter below for details on the number of jobs which  are
         suspended.

      nsuspend
         The number of jobs  which  are  suspended/enabled  per  time
         interval  if  at  least  one  of  the load thresholds in the
         suspend_thresholds   list   is    exceeded    or    if    no
         suspend_threshold    is   violated   anymore   respectively.
         Nsuspend jobs are suspended in each time interval  until  no
         suspend_thresholds  are  exceeded anymore or all jobs in the
         queue are suspended. Jobs are enabled in  the  corresponding
         way  if  the suspend_thresholds are no longer exceeded.  The
         time interval in which the suspensions of the jobs occur  is
         defined in suspend_interval below.

      suspend_interval
         The  time  interval  in  which  further  nsuspend  jobs  are
         suspended  if  one  of the suspend_thresholds (see above for
         both) is exceeded by the current load on the host  on  which
         the  queue  is located.  The time interval is also used when
         enabling the jobs.

      migr_load_thresholds
         A list of load thresholds with the same semantics as that of
         the   load_thresholds  parameter  (see  above)  except  that
         exceeding one of the denoted thresholds initiates  migration
         of the jobs from the queue.  This parameter has no effect in
         this release.

      priority
         The priority parameter specifies the nice(2) value at  which
         jobs  in  this queue will be run. The type is number and the
         default is zero (which means no nice  value  is  set  expli-
         citly).

      max_migr_time
         The time reserved for checkpointing jobs to be migrated  and
         aborted.   Checkpointing  jobs  due  to be aborted are first
         sent a SIGTSTP. Everyone in the concerned process group  may
         catch  this  signal  and  may  react  appropriately.   After
         max_migr_time seconds, a SIGKILL is sent and  the  processes
         are aborted.  Note: If you set max_migr_time too high a user
         requesting full interactive usage may  suffer  max_migr_time
         seconds  from a still running job.  Max_migr_time is of type
         time and The default is 0 seconds.

      migr_load_thresholds
         A list of load thresholds with the same semantics as that of
         the   load_thresholds  parameter  (see  above)  except  that
         exceeding one of the denoted thresholds initiates  migration
         of  checkpointing jobs from the queue.  It is recommended to
         set  the  migration  load  values  high  enough  above   the
         load_thresholds  to prevent the jobs from forcing migrations
         by their own activity.

      max_no_migr
         The time a checkpointing job is allowed  to  spend  in  non-
         interruptible   sections   of   the   batch   script.   Non-
         interruptible sections are  everything  outside  qrestart(1)
         commands.  If a job exceeds this time limit it is killed and
         the job owner is notified. The default for max_no_migr is  2
         minutes. It is of type time.

      min_cpu_interval
         The time between two automatic checkpoints in case of  tran-
         sparently  checkpointing  jobs.  The  maximum  of  the  time
         requested by the user via qsub(1) and the  time  defined  by
         the  queue  configuration  is  used  as checkpoint interval.
         Since checkpoint files may be considerably  large  and  thus
         writing  them to the file system may become expensive, users
         and administrators are advised to choose sufficiently  large
         time  intervals.  min_cpu_interval  is  of type time and the
         default is 5 minutes (which usually  is  suitable  for  test
         purposes only).

      processors
         A set of processors in case of  a  multiprocessor  execution
         host  can  be  defined  to  which the jobs executing in this
         queue are bound. The value type of this parameter is a range
         description  like that of the -pe option of qsub(1) (e.g. 1-
         4,8,10) denoting the processor  numbers  for  the  processor
         group  to  be  used.  Obviously  the interpretation of these
         values relies on operating system specifics and is thus per-
         formed inside sge_execd(8) running on the queue host. There-
         fore, the parsing of the parameter has to be provided by the
         execution  daemon  and  the parameter is only passed through
         sge_qmaster(8) as a string.

         Currently, support is only provided for  SGI  multiprocessor
         machines  running  IRIX  6.2 and Digital UNIX multiprocessor
         machines. In the case of Digital UNIX only one job per  pro-
         cessor  set  is  allowed  to  execute at the same time, i.e.
         slots (see above) should be set to 1 for this queue.

      qtype
         The type of queue.  Currently  one  of  batch,  interactive,
         parallel  or  checkpointing  or  any  combination in a comma
         separated list.  Alternatively, if the Grid  Engine  Queuing
         System Interface (QSI) option is licensed, the type transfer
         can be specified to indicate a queue which passes jobs on to
         a foreign queuing system. Deprecated in the current version.

         (type string; default: batch).

      rerun
         Defines a default behavior for jobs  which  are  aborted  by
         system crashes or manual "violent" (via kill(1)) shutdown of
         the   complete   Grid   Engine   system    (including    the
         sge_shepherd(8)  of the jobs and their process hierarchy) on
         the queue host. As soon as  sge_execd(8)  is  restarted  and
         detects  that a job has been aborted for such reasons it can
         be restarted if the jobs are restartable. A job may  not  be
         restartable,  for  example,  if  it updates databases (first
         reads then writes to the same  record  of  a  database/file)
         because  the  abortion of the job may have left the database
         in an inconsistent state. If the owner of  a  job  wants  to
         overrule  the default behavior for the jobs in the queue the
         -r option of qsub(1) can be used.

         The type of this parameter is boolean, thus either  TRUE  or
         FALSE  can  be  specified. The default is FALSE, i.e. do not
         restart jobs automatically.

      slots
         The maximum number of concurrently executing jobs allowed in
         the queue.  Type is number.

      tmpdir
         The tmpdir parameter specifies the absolute path to the base
         of  the  temporary  directory  filesystem. When sge_execd(8)
         launches a job, it creates  a  uniquely-named  directory  in
         this  filesystem  for  the  purpose of holding scratch files
         during job execution. At job completion, this directory  and
         its  contents  are  removed  automatically.  The environment
         variables TMPDIR and TMP are set to the path  of  each  jobs
         scratch directory (type string; default: /tmp).

      shell
         If either posix_compliant or script_from_stdin is  specified
         as  the  shell_start_mode parameter in sge_conf(5) the shell
         parameter specifies  the  executable  path  of  the  command
         interpreter  (e.g.   sh(1)  or csh(1)) to be used to process
         the job scripts executed in the  queue.  The  definition  of
         shell  can  be overruled by the job owner via the qsub(1) -S
         option.

         The  type  of  the  parameter  is  string.  The  default  is
         /bin/csh.

      shell_start_mode
         This parameter defines the  mechanisms  which  are  used  to
         actually  invoke the job scripts on the execution hosts. The
         following values are recognized:

         unix_behavior
              If a user starts a job shell script under UNIX interac-
              tively  by  invoking  it  just with the script name the
              operating system's executable loader uses the  informa-
              tion  provided in a comment such as `#!/bin/csh' in the
              first line of the script to detect which command inter-
              preter to start to interpret the script. This mechanism
              is  used  by  Grid  Engine  when   starting   jobs   if
              unix_behavior is defined as shell_start_mode.

         posix_compliant
              POSIX does not consider first script line comments such
              a `#!/bin/csh' as being significant. The POSIX standard
              for batch queuing systems (P1003.2d) therefore requires
              a  compliant queuing system to ignore such lines but to
              use user specified or configured default command inter-
              preters  instead.  Thus,  if shell_start_mode is set to
              posix_compliant Grid Engine will either use the command
              interpreter  indicated  by the -S option of the qsub(1)
              command or the shell parameter of the queue to be  used
              (see above).

         script_from_stdin
              Setting  the  shell_start_mode  parameter   either   to
              posix_compliant  or  unix_behavior  requires you to set
              the umask in use for sge_execd(8) such that every  user
              has  read  access  to  the active_jobs directory in the
              spool directory of the corresponding execution  daemon.
              In  case you have prolog and epilog scripts configured,
              they also need to be readable by any user who may  exe-
              cute jobs.
              If this violates your site's security policies you  may
              want to set shell_start_mode to script_from_stdin. This
              will force Grid Engine to open the job script  as  well
              as  the  epilogue and prologue scripts for reading into
              STDIN as root (if sge_execd(8)  was  started  as  root)
              before  changing  to the job owner's user account.  The
              script is then fed into the STDIN stream of the command
              interpreter  indicated  by the -S option of the qsub(1)
              command or the shell parameter of the queue to be  used
              (see above).
              Thus setting shell_start_mode to script_from_stdin also
              implies  posix_compliant  behavior. Note, however, that
              feeding scripts into the  STDIN  stream  of  a  command
              interpreter  may  cause trouble if commands like rsh(1)
              are invoked inside a job script as  they  also  process
              the  STDIN  stream  of  the  command interpreter. These
              problems can usually be  resolved  by  redirecting  the
              STDIN  channel of those commands to come from /dev/null
              (e.g. rsh host date < /dev/null). Note also,  that  any
              command-line options associated with the job are passed
              to the executing shell. The  shell  will  only  forward
              them  to  the  job  if they are not recognized as valid
              shell options.

         The default for shell_start_mode is posix_compliant.

      klog
         The executable path of the klog utility on the  queue  host.
         It is used for AFS reauthentication. The type of the parame-
         ter is string; the default is /usr/local/bin/klog.

         Not supported in this release.

      prolog
         The executable path of a shell script that is started before
         execution of Grid Engine jobs with the same environment set-
         ting as that for the Grid Engine jobs to be  started  after-
         wards.  An  optional prefix "user@" specifies the user under
         which this procedure is to be started.   This  procedure  is
         intended  as  a  means  for the Grid Engine administrator to
         automate the execution of general site specific  tasks  like
         the  preparation of temporary file systems with the need for
         the same context information as the job. This  queue  confi-
         guration  entry  overwrites cluster global or execution host
         specific prolog definitions (see sge_conf(5)).

         Note: prolog is executed exactly as the job script.   There-
         fore,   all  implications  described  under  the  parameters
         shell_start_mode and login_shells below apply.

         The default for prolog is  the  special  value  NONE,  which
         prevents  from execution of a prologue script.  The  special
         variables for constituting a command line are the same  like
         in  prolog  definitions  of  the  cluster configuration (see
         sge_conf(5)).

      epilog
         The executable path of a shell script that is started  after
         execution of Grid Engine jobs with the same environment set-
         ting as that for the Grid Engine jobs  that  has  just  com-
         pleted.  An optional prefix "user@" specifies the user under
         which this procedure is to be started.   This  procedure  is
         intended  as  a  means  for the Grid Engine administrator to
         automate the execution of general site specific  tasks  like
         the  cleaning up of temporary file systems with the need for
         the same context information as the job. This  queue  confi-
         guration  entry  overwrites cluster global or execution host
         specific epilog definitions (see sge_conf(5)).

         Note: epilog is executed exactly as the job script.   There-
         fore,   all  implications  described  under  the  parameters
         shell_start_mode and login_shells below apply.

         The default for epilog is  the  special  value  NONE,  which
         prevents  from execution of a epilogue script.  The  special
         variables for constituting a command line are the same  like
         in  prolog  definitions  of  the  cluster configuration (see
         sge_conf(5)).

      starter_method
         The executable path given here is intended to be used  as  a
         starter  facility  which is responsible for starting the job
         itself.

         Not supported in this release.

      suspend_method
      resume_method
      terminate_method
         These parameters can be used  for  overwriting  the  default
         method  used  by  Grid  Engine  for suspension, release of a
         suspension and for termination of a job.  Per  default,  the
         signals  SIGSTOP,  SIGCONT  and SIGKILL are delivered to the
         job to perform these actions. However, for some applications
         this is not appropriate.

         If no executable path is given, Grid Engine takes the speci-
         fied parameter entries as the signal to be delivered instead
         of the default signal. A signal must be  either  a  positive
         number  or a signal name with "SIG" as prefix and the signal
         name as printed by kill -l (e.g.  SIGTERM).

         If an executable path is given (it must be an absolute  path
         starting  with  a  "/")  then this command together with its
         arguments is started by Grid Engine to perform the appropri-
         ate  action. The following special variables are expanded at
         runtime and can be used (besides  any  other  strings  which
         have  to  be  interpreted by the procedures) to constitute a
         command line:

         $host
              The name of the host on which the procedure is started.

         $job_owner
              The user name of the job owner.

         $job_id
              Grid Engine's unique job identification number.

         $job_name
              The name of the job.

         $queue
              The name of the queue.

         $job_pid
              The pid of the job.

      reauth_time
         The time  gap  between  consecutive  AFS  reauthentications.
         Reauth_time  should  be less than the ticket expiration time
         that is configured for the local AFS installation. The  type
         of the parameter is time and the default value is 1 hour and
         40 minutes, i.e. 100 minutes.

         Not supported in this release.

      notify
         The time waited between delivery of SIGUSR1/SIGUSR2  notifi-
         cation signals and suspend/kill signals if job was submitted
         with the qsub(1) -notify option.

      owner_list
         The owner_list names the login names (in a  comma  separated
         list)  of  those  users  who  are authorized to suspend this
         queue (Grid Engine operators and managers can suspend queues
         by default). It is customary to set this field for queues on
         interactive workstations where the computing  resources  are
         shared  between  interactive  sessions and Grid Engine jobs,
         allowing the workstation owner to have priority access (type
         string; default: NONE).

      user_lists
         The user_lists parameter contains a comma separated list  of
         so  called user access lists as described in access_list(5).
         Each user contained in at least one of the  enlisted  access
         lists  has  access to the queue. If the user_lists parameter
         is set to NONE (the default) any user has access  being  not
         explicitly  excluded via the xuser_lists parameter described
         below.  If a user  is  contained  both  in  an  access  list
         enlisted  in  xuser_lists  and user_lists the user is denied
         access to the queue.

      xuser_lists
         The xuser_lists parameter contains a comma separated list of
         so  called user access lists as described in access_list(5).
         Each user contained in at least one of the  enlisted  access
         lists is not allowed to access the queue. If the xuser_lists
         parameter is set to NONE (the default) any user has  access.
         If  a  user  is contained both in an access list enlisted in
         xuser_lists and user_lists the user is denied access to  the
         queue.

      projects
         The projects parameter contains a comma  separated  list  of
         projects  that have access to the queue. Any projects not in
         this list are denied access to the queue.  If  set  to  NONE
         (the  default),  any project has access that is not specifi-
         cally excluded via the xprojects parameter described  below.
         If  a  project is in both the projects and xprojects parame-
         ters, the project is  denied  access  to  the  queue.   This
         parameter is only available in a Grid Engine Enterprise Edi-
         tion system.

      xprojects
         The xprojects parameter contains a comma separated  list  of
         projects that are denied access to the queue. If set to NONE
         (the default), no projects  are  denied  access  other  than
         those   denied   access  based  on  the  projects  parameter
         described above.  If a project is in both the  projects  and
         xprojects  parameters,  the  project is denied access to the
         queue.  This parameter is only available in  a  Grid  Engine
         Enterprise Edition system.

      subordinate_list
         A list of Grid Engine queues, residing on the same  host  as
         the  configured  queue, to suspend when a specified count of
         jobs is running in this queue.  The  list  specification  is
         the  same  as  that  of the load_thresholds parameter above,
         e.g. low_pri_q=5,small_q. The numbers denote the  job  slots
         of  the  queue that have to be filled to trigger the suspen-
         sion of the subordinated queue. If no value  is  assigned  a
         suspension  is  triggered  if  all  slots  of  the queue are
         filled.
         On nodes which host more than one queue, you might  wish  to
         accord  better  service  to  certain  classes of jobs (e.g.,
         queues that are dedicated to parallel processing might  need
         priority  over  low  priority  production  queues;  default:
         NONE).

      complex_list
         The comma separated list of administrator defined  complexes
         (see  complex(5)  for  details)  to  be  associated with the
         queue.  Only complex attributes contained  in  the  enlisted
         complexes  and  those  from the "global", "host" and "queue"
         complex, which are implicitly attached to each queue, can be
         used in the complex_values list below.

         The default value  for  this  parameter  is  NONE,  i.e.  no
         administrator  defined  complexes  are  associated  with the
         queue.

      complex_values
         complex_values  defines  quotas  for   resource   attributes
         managed  via  this queue.  The allowed complex attributes to
         appear in complex_values are defined  by  complex_list  (see
         above).   The syntax is the same as for load_thresholds (see
         above). The quotas are related to the  resource  consumption
         of  all  jobs in a queue in the case of consumable resources
         (see complex(5) for details on consumable resources) or they
         are  interpreted on a per queue slot (see slots above) basis
         in the case of non-consumable resources. Consumable resource
         attributes  are  commonly  used  to manage free memory, free
         disk space or available  floating  software  licenses  while
         non-consumable attributes usually define distinctive charac-
         teristics like type of hardware installed.

         For consumable resource  attributes  an  available  resource
         amount  is  determined  by  subtracting the current resource
         consumption of all running jobs in the queue from the  quota
         in the complex_values list. Jobs can only be dispatched to a
         queue if  no  resource  requests  exceed  any  corresponding
         resource  availability  obtained  by  this scheme. The quota
         definition  in  the  complex_values  list  is  automatically
         replaced  by the current load value reported for this attri-
         bute, if load is monitored for  this  resource  and  if  the
         reported  load  value is more stringent than the quota. This
         effectively avoids oversubscription of resources.

         Note: Load values replacing  the  quota  specifications  may
         have  become  more  stringent  because they have been scaled
         (see host_conf(5)) and/or load adjusted (see sched_conf(5)).
         The  -F  option  of  qstat(1)  and  the  load display in the
         qmon(1) queue control dialog (activated  by  clicking  on  a
         queue  icon  while  the  "Shift"  key  is  pressed)  provide
         detailed  information  on   the   actual   availability   of
         consumable  resources  and on the origin of the values taken
         into account currently.

         Note also: The resource consumption of  running  jobs  (used
         for  the  availability  calculation) as well as the resource
         requests of the jobs waiting to be dispatched either may  be
         derived  from  explicit  user requests during job submission
         (see the -l option to qsub(1)) or  from  a  "default"  value
         configured  for  an attribute by the administrator (see com-
         plex(5)).  The  -r  option  to  qstat(1)  can  be  used  for
         retrieving  full  detail  on the actual resource requests of
         all jobs in the system.

         For non-consumable resources Grid Engine simply compares the
         job's  attribute  requests with the corresponding specifica-
         tion in complex_values taking the relation operator  of  the
         complex  attribute definition into account (see complex(5)).
         If the result of the comparison  is  "true",  the  queue  is
         suitable  for  the job with respect to the particular attri-
         bute. For parallel jobs each queue slot to be occupied by  a
         parallel  task  is meant to provide the same resource attri-
         bute value.

         Note: Only numeric complex attributes can be defined as con-
         sumable  resources  and  hence  non-numeric  attributes  are
         always handled on a per queue slot basis.

         The default value  for  this  parameter  is  NONE,  i.e.  no
         administrator  defined resource attribute quotas are associ-
         ated with the queue.

      calendar
         specifies the calendar to be valid for this  queue  or  con-
         tains  NONE (the default). A calendar defines the availabil-
         ity of a queue depending on time  of  day,  week  and  year.
         Please  refer  to  calendar_conf(5)  for details on the Grid
         Engine calendar facility.

         Note: Jobs can request queues with a certain calendar  model
         via a "-l c=<cal_name>" option to qsub(1).

      initial_state
         defines an initial state for the queue  either  when  adding
         the queue to the system for the first time or on start-up of
         the sge_execd(8) on the host on  which  the  queue  resides.
         Possible values are:

         default   The queue is enabled when adding the queue  or  is
                   reset  to  the  previous  status when sge_execd(8)
                   comes up (this corresponds to the behavior in ear-
                   lier   Grid   Engine   releases   not   supporting
                   initial_state).

         enabled   The queue is  enabled  in  either  case.  This  is
                   equivalent to a manual and explicit 'qmod -e' com-
                   mand (see qmod(1)).

         disabled  The queue is  disable  in  either  case.  This  is
                   equivalent to a manual and explicit 'qmod -d' com-
                   mand (see qmod(1)).

      fshare
         This parameter is only available in a Grid Engine Enterprise
         Edition system. Grid Engine does not support this parameter.

         The functional shares of the queue (i.e.  job  class).  Jobs
         executing  in  this queue may get functional tickets derived
         from the relative importance of the queue if the  functional
         policy is activated.

      oticket
         This parameter is only available in a Grid Engine Enterprise
         Edition system. Grid Engine does not support this parameter.

         The override tickets of the queue  (i.e.  job  class).  Grid
         Engine  Enterprise Edition distributes the configured amount
         of override tickets among all jobs executing in this queue.

    RESOURCE LIMITS
         The first two resource limit parameters, s_rt and h_rt,  are
         implemented  by  Grid Engine. They define the "real time" or
         also called "elapsed" or "wall  clock"  time  having  passed
         since  the  start  of  the job. If h_rt is exceeded by a job
         running in the queue, it is aborted via the  SIGKILL  signal
         (see  kill(1)).   If  s_rt  is  exceeded,  the  job is first
         "warned" via the SIGUSR1 signal (which can be caught by  the
         job) and finally aborted after the notification time defined
         in the queue configuration parameter notify (see above)  has
         passed.

         The resource limit parameters s_cpu  and  h_cpu  are  imple-
         mented by Grid Engine as a job limit. They impose a limit on
         the  amount  of  combined  CPU  time  consumed  by  all  the
         processes  in the job. If h_cpu is exceeded by a job running
         in the queue, it  is  aborted  via  a  SIGKILL  signal  (see
         kill(1)).   If  s_cpu is exceeded, the job is sent a SIGXCPU
         signal which can be caught by the job. If you wish to  allow
         a  job to be "warned" so it can exit gracefully before it is
         killed then you should set the s_cpu limit to a lower  value
         than  h_cpu.   For  parallel processes, the limit is applied
         per slot which means that the limit  is  multiplied  by  the
         number of slots being used by the job before being applied.

         The resource limit parameters s_vmem and h_vmem  are  imple-
         mented by Grid Engine as a job limit. They impose a limit on
         the amount of combined virtual memory consumed  by  all  the
         processes in the job. If h_vmem is exceeded by a job running
         in the queue, it  is  aborted  via  a  SIGKILL  signal  (see
         kill(1)).   If s_vmem is exceeded, the job is sent a SIGXCPU
         signal which can be caught by the job.  If you wish to allow
         a  job to be "warned" so it can exit gracefully before it is
         killed then you should set the s_vmem limit to a lower value
         than  h_vmem.   For parallel processes, the limit is applied
         per slot which means that the limit  is  multiplied  by  the
         number of slots being used by the job before being applied.

         The remaining parameters in the queue configuration template
         specify per job soft and hard resource limits as implemented
         by the setrlimit(2) system call. See  this  manual  page  on
         your  system  for  more information.  By default, each limit
         field is set  to  infinity  (which  means  RLIM_INFINITY  as
         described  in  the setrlimit(2) manual page). The value type
         for the CPU-time limits s_cpu and h_cpu is time.  The  value
         type  for the other limits is memory.  Note: Not all systems
         support setrlimit(2).

         Note also: s_vmem  and  h_vmem  (virtual  memory)  are  only
         available    on    systems   supporting   RLIMIT_VMEM   (see
         setrlimit(2) on your operating system).

         The UNICOS operating system supplied by  SGI/Cray  does  not
         support  the  setrlimit(2)  system  call,  using  their  own
         resource limit-setting system call instead.  For UNICOS sys-
         tems only, the following meanings apply:

         s_cpu     The per-process CPU time limit in seconds.

         s_core    The per-process maximum core file size in bytes.

         s_data    The per-process maximum memory limit in bytes.

         s_vmem    The same as s_data (if both are set the minimum is
                   used).

         h_cpu     The per-job CPU time limit in seconds.

         h_data    The per-job maximum memory limit in bytes.

         h_vmem    The same as h_data (if both are set the minimum is
                   used).

         h_fsize   The total number of disk blocks that this job  can
                   create.
