9 This page summarizes the resources supported by PBS for SGI worksta‐
10 tions running IRIX 6. These resources are specified by including them
11 in the -l option argument on the qsub or qalter command or in the PBS
12 job script.
13
15 cput Maximum amount of CPU time used by all processes in the job.
16 Units: time.
17 file The largest size of any single file that may be created by
19 the job. Units: size.
20 ncpus The number of processors requested. Units: unitary.
22 cpupercent
24 The maximum percentage of a cpu which the job used. A value
25 of 100 means 1 cpu. This cannot be set, it is only reported.
26 Units: percent.
27 nice The nice value under which the job is to be run. Units: uni‐
29 tary.
30 nodemask A bit mask specifying the nodes (a pair of processors) to be
32 associated with this job. This resource is intended for use
33 by PBS to optimize processor allocation and direct use of
34 this field by the job owner is discouraged. Units: bit mask.
35 pcput Maximum amount of CPU time used by any single process in the
37 job. Units: time.
38 pmem Maximum amount of physical memory (workingset) used by any
40 single process of the job. Units: size.
41 pvmem Maximum amount of virtual memory used by any single process
43 in the job. Units: size.
44 vmem Maximum amount of virtual memory used by all concurrent pro‐
46 cesses in the job. Units: size.
47 walltime Maximum amount of real time during which the job can be in
49 the running state. Units: time.
50 arch Specifies the administrator defined system architecture re‐
52 quried. This defaults to whatever the PBS_MACH string is set
53 to in "local.mk". Units: string.
54 host Name of host on which job should be run. This resource is
56 provided for use by the site's scheduling policy. The al‐
57 lowable values and effect on job placement is site dependent.
58 Units: string.
59 nodes Number and/or type of nodes to be reserved for exclusive use
61 by the job. The value is one or more node_specs joined with
62 the '+' character, "node_spec[+node_spec...]. Each node_spec
63 is an number of nodes required of the type declared in the
64 node_spec and a name or one or more property or properties
65 desired for the nodes. The number, the name, and each prop‐
66 erty in the node_spec are separated by a colon ':'. If no
67 number is specified, one (1) is assumed. Units: string.
68 The name of a node is its hostname. The properties of nodes
70 are:
71 . ppn=# specifying the number of processors per node re‐
73 quested. Defaults to 1.
74 . arbitrary string assigned by the system administrator,
76 please check with your administrator as to the node names
77 and properties available to you.
78 Examples:
80 . To ask for 12 nodes of any type: -l nodes=12
82 . To ask for 2 "server" nodes and 14 other nodes (a total of
84 16): -l nodes=2:server+14
85 The above consist of two node_specs "2:server" and "14".
86 . To ask for (a) 1 node that is a "server" and has a "hippi"
88 interface, (b) 10 nodes that are not servers, and (c) 3
89 nodes that have a large amount of memory an have hippi:
90 -l nodes=server:hippi+10:noserver+3:bigmem:hippi
91 . To ask for three nodes by name:
93 -l nodes=b2005+b1803+b1813
94 . To ask for 2 processors on each of four nodes:
96 -l nodes=4:ppn=2
97 . To ask for 4 processors on one node:
99 -l nodes=1:ppn=4
100 . To ask for 2 processors on each of two blue nodes and three
102 processors on one red node:
103 -l nodes=2:blue:ppn=2+red:ppn=3
104 host Allows a user to specify the desired execution location.
106 This resource is provided for use by the site's scheduling
107 policy. The allowable values and effect on job placement is
108 site dependent. Units: string.
109 other Allows a user to specify site specific information. This re‐
111 source is provided for use by the site's scheduling policy.
112 The allowable values and effect on job placement is site de‐
113 pendent. Units: string.
114 software Allows a user to specify software required by the job. This
116 is useful if certain software packages are only available on
117 certain systems in the site. This resource is provided for
118 use by the site's scheduling policy. The allowable values
119 and effect on job placement is site dependent. Units:
120 string.
121
123 qsub -l nodes=15,walltime=2:00:00 script
124 or in a qsub script as a directive:
126 #PBS -l nodes=15,walltime=2:00:00
128 qsub -l cput=1:00:00,walltime=2:00:00,file=50gb,vmem=15mb script
131 qalter -lcput=30:00,pmem=8mb 123.jobid
132 or in a qsub script as a directive:
134 #PBS -l cput=1:00:00,walltime=2:00:00,file=50gb,mem=15mb
136
138 The resource values take the following units:
139 time specifies a maximum time period the resource can be used. Time
141 is expressed in seconds as an integer, or in the form:
142 [[hours:]minutes:]seconds[.milliseconds]
143 size specifies the maximum amount in terms of bytes or words. It is
145 expressed in the form integer[suffix] The suffix is a multi‐
146 plier defined in the following table, The size of a word is the
147 word size on the execution host.
148 b or w bytes or words.
150 kb or kw Kilo (1024) bytes or words.
152 mb or mw Mega (1,048,576) bytes or words.
154 gb or gw Giga (1,073,741,824) bytes or words.
156 unitary The maximum amount of a resource which is expressed as a simple
158 integer.
