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  allow-
	      able 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.
