NAME

6       pbs_resources_sp2 - pbs resources on IBM SP-2

DESCRIPTION

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

RESOURCES

14       nice   The  nice  value  under which the job is to be run.  Units: uni‐
15              tary.
16
17       walltime
18              Maximum amount of real time during which the job can be  in  the
19              running state.  Units: time.
20
21       arch   Specifies   the   administrator   defined   system  architecture
22              requried.  This defaults to whatever the PBS_MACH string is  set
23              to in "local.mk".  Units: string.
24
25       host   Name  of host on which job should be run.  This resource is pro‐
26              vided for use by the site's scheduling policy.    The  allowable
27              values  and  effect  on job placement is site dependent.  Units:
28              string.
29
30       nodes  Number and/or type of nodes to be reserved for exclusive use  by
31              the  job.   The  value is one or more node_specs joined with the
32              '+' character, "node_spec[+node_spec...].  Each node_spec is  an
33              number  of  nodes required of the type declared in the node_spec
34              and a name or one or more properity or properities  desired  for
35              the  nodes.   The  number,  the  name, and each properity in the
36              node_spec are separated by a colon ':'.  If no number is  speci‐
37              fied, one (1) is assumed.  Units: string.
38
39              The  name  of  a node is its hostname.  The properities of nodes
40              are:
41
42              . ppn=# specifying the number of processors per node  requested.
43                Defaults to 1.
44
45              . arbitrary  string assigned by the system administrator, please
46                check with your administrator as to the node names and proper‐
47                ities available to you.
48
49              Examples:
50
51              . To ask for 12 nodes of any type: -l nodes=12
52
53              . To  ask  for  2  "server" nodes and 14 other nodes (a total of
54                16): -l nodes=2:server+14
55                The above consist of two node_specs "2:server" and "14".
56
57              . To ask for (a) 1 node that is a "server"  and  has  a  "hippi"
58                interface,  (b) 10 nodes that are not servers, and (c) 3 nodes
59                that have a large amount of memory an have hippi:
60                -l nodes=server:hippi+10:noserver+3:bigmem:hippi
61
62              . To ask for three nodes by name:
63                -l nodes=b2005+b1803+b1813
64
65              . To ask for 2 processors on each of four nodes:
66                -l nodes=4:ppn=2
67
68              . To ask for 4 processors on one node:
69                -l nodes=1:ppn=4
70
71              . To ask for 2 processors on each of two blue  nodes  and  three
72                processors on one red node:
73                -l nodes=2:blue:ppn=2+red:ppn=3
74
75       host   Allows  a  user to specify the desired execution location.  This
76              resource is provided for use by the  site's  scheduling  policy.
77              The  allowable values and effect on job placement is site depen‐
78              dent.  Units: string.
79
80       other  Allows a  user  to  specify  site  specific  information.   This
81              resource  is  provided  for use by the site's scheduling policy.
82              The allowable values and effect on job placement is site  depen‐
83              dent.  Units: string.
84
85       software
86              Allows a user to specify software required by the job.   This is
87              useful if certain software packages are only available  on  cer‐
88              tain  systems in the site.  This resource is provided for use by
89              the site's scheduling policy.  The allowable values  and  effect
90              on job placement is site dependent.  Units: string.
91

EXAMPLES

93       qsub -l nodes=15,walltime=2:00:00 script
94
95       or in a qsub script as a directive:
96
97       #PBS -l nodes=15,walltime=2:00:00

RESOURCE UNITS

101       The resource values take the following units:
102
103       time    specifies a maximum time period the resource can be used.  Time
104               is expressed in seconds as an integer, or in the form:
105               [[hours:]minutes:]seconds[.milliseconds]
106
107       unitary The maximum amount of a resource which is expressed as a simple
108               integer.
