NAME

       pbs_resources_sp2 - pbs resources on IBM SP-2

DESCRIPTION

       This page summarizes the resources supported by PBS for the IBM SP-2.  These resources are
       specified by including them in the -l option argument on the qsub or qalter command or  in
       the PBS job script.

RESOURCES

       nice   The nice value under which the job is to be run.  Units: unitary.

       walltime
              Maximum  amount  of  real  time  during  which the job can be in the running state.
              Units: time.

       arch   Specifies the administrator defined system architecture requried.  This defaults to
              whatever the PBS_MACH string is set to in "local.mk".  Units: string.

       host   Name  of host on which job should be run.  This resource is provided for use by the
              site's scheduling policy.   The allowable values and effect  on  job  placement  is
              site dependent.  Units: string.

       nodes  Number and/or type of nodes to be reserved for exclusive use by the job.  The value
              is one or more node_specs joined with the '+' character, "node_spec[+node_spec...].
              Each node_spec is an number of nodes required of the type declared in the node_spec
              and a name or one or more properity or properities  desired  for  the  nodes.   The
              number, the name, and each properity in the node_spec are separated by a colon ':'.
              If no number is specified, one (1) is assumed.  Units: string.

              The name of a node is its hostname.  The properities of nodes are:

              . ppn=# specifying the number of processors per node requested.  Defaults to 1.

              . arbitrary string assigned by the system administrator,  please  check  with  your
                administrator as to the node names and properities available to you.

              Examples:

              . To ask for 12 nodes of any type: -l nodes=12

              . To   ask   for   2   "server"   nodes  and  14  other  nodes  (a  total  of  16):
                -l nodes=2:server+14
                The above consist of two node_specs "2:server" and "14".

              . To ask for (a) 1 node that is a "server" and has  a  "hippi"  interface,  (b)  10
                nodes that are not servers, and (c) 3 nodes that have a large amount of memory an
                have hippi:
                -l nodes=server:hippi+10:noserver+3:bigmem:hippi

              . To ask for three nodes by name:
                -l nodes=b2005+b1803+b1813

              . To ask for 2 processors on each of four nodes:
                -l nodes=4:ppn=2

              . To ask for 4 processors on one node:
                -l nodes=1:ppn=4

              . To ask for 2 processors on each of two blue nodes and three processors on one red
                node:
                -l nodes=2:blue:ppn=2+red:ppn=3

       host   Allows a user to specify the desired execution location.  This resource is provided
              for use by the site's scheduling policy.  The allowable values and  effect  on  job
              placement is site dependent.  Units: string.

       other  Allows  a user to specify site specific information.  This resource is provided for
              use by the site's scheduling policy.   The  allowable  values  and  effect  on  job
              placement is site dependent.  Units: string.

       software
              Allows  a user to specify software required by the job.   This is useful if certain
              software packages are only available on certain systems in the site.  This resource
              is  provided  for  use  by  the site's scheduling policy.  The allowable values and
              effect on job placement is site dependent.  Units: string.

EXAMPLES

       qsub -l nodes=15,walltime=2:00:00 script

       or in a qsub script as a directive:

       #PBS -l nodes=15,walltime=2:00:00

RESOURCE UNITS

       The resource values take the following units:

       time    specifies a maximum time period the resource can be used.  Time  is  expressed  in
               seconds as an integer, or in the form:
               [[hours:]minutes:]seconds[.milliseconds]

       unitary The maximum amount of a resource which is expressed as a simple integer.
