pbs_resources_sp2(7B) PBS pbs_resources_sp2(7B) 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 argu- ment 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: uni- tary. 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 re- quried. 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 pro- vided 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 speci- fied, 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 proper- ities 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" in- terface, (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 depen- dent. Units: string. other Allows a user to specify site specific information. This re- source 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 cer- tain 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.
