7
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.
12
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 re‐
22 quried. This defaults to whatever the PBS_MACH string is set to
23 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 property or properties desired for the
35 nodes. The number, the name, and each property in the node_spec
36 are separated by a colon ':'. If no number is specified, one
37 (1) is assumed. Units: string.
38
39 The name of a node is its hostname. The properties 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 ties 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" in‐
58 terface, (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 re‐
81 source is provided for use by the site's scheduling policy. The
82 allowable values and effect on job placement is site dependent.
83 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
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
98
99
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.
