9 This page summarizes the resources supported by PBS for PC workstations
10 running Darwin. These resources are specified by including them in the
11 -l option argument on the qsub or qalter command or in the PBS job
12 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 nice The nice value under which the job is to be run. Units: uni‐
22 tary.
23 pcput Maximum amount of CPU time used by any single process in the
25 job. Units: time.
26 pmem Maximum amount of physical memory (workingset) used by any
28 single process of the job. Units: size.
29 pvmem Maximum amount of virtual memory used by any single process
31 in the job. Units: size.
32 vmem Maximum amount of virtual memory used by all concurrent pro‐
34 cesses in the job. Units: size.
35 walltime Maximum amount of real time during which the job can be in
37 the running state. Units: time.
38 arch Specifies the administrator defined system architecture re‐
40 quried. This defaults to whatever the PBS_MACH string is set
41 to in "local.mk". Units: string.
42 host Name of host on which job should be run. This resource is
44 provided for use by the site's scheduling policy. The al‐
45 lowable values and effect on job placement is site dependent.
46 Units: string.
47 nodes Number and/or type of nodes to be reserved for exclusive use
49 by the job. The value is one or more node_specs joined with
50 the '+' character, "node_spec[+node_spec...]. Each node_spec
51 is an number of nodes required of the type declared in the
52 node_spec and a name or one or more property or properties
53 desired for the nodes. The number, the name, and each prop‐
54 erty in the node_spec are separated by a colon ':'. If no
55 number is specified, one (1) is assumed. Units: string.
56 The name of a node is its hostname. The properties of nodes
58 are:
59 . ppn=# specifying the number of processors per node re‐
61 quested. Defaults to 1.
62 . arbitrary string assigned by the system administrator,
64 please check with your administrator as to the node names
65 and properties available to you.
66 Examples:
68 . To ask for 12 nodes of any type: -l nodes=12
70 . To ask for 2 "server" nodes and 14 other nodes (a total of
72 16): -l nodes=2:server+14
73 The above consist of two node_specs "2:server" and "14".
74 . To ask for (a) 1 node that is a "server" and has a "hippi"
76 interface, (b) 10 nodes that are not servers, and (c) 3
77 nodes that have a large amount of memory an have hippi:
78 -l nodes=server:hippi+10:noserver+3:bigmem:hippi
79 . To ask for three nodes by name:
81 -l nodes=b2005+b1803+b1813
82 . To ask for 2 processors on each of four nodes:
84 -l nodes=4:ppn=2
85 . To ask for 4 processors on one node:
87 -l nodes=1:ppn=4
88 . To ask for 2 processors on each of two blue nodes and three
90 processors on one red node:
91 -l nodes=2:blue:ppn=2+red:ppn=3
92 host Allows a user to specify the desired execution location.
94 This resource is provided for use by the site's scheduling
95 policy. The allowable values and effect on job placement is
96 site dependent. Units: string.
97 other Allows a user to specify site specific information. This re‐
99 source is provided for use by the site's scheduling policy.
100 The allowable values and effect on job placement is site de‐
101 pendent. Units: string.
102 software Allows a user to specify software required by the job. This
104 is useful if certain software packages are only available on
105 certain systems in the site. This resource is provided for
106 use by the site's scheduling policy. The allowable values
107 and effect on job placement is site dependent. Units:
108 string.
109
111 qsub -l nodes=15,walltime=2:00:00 script
112 or in a qsub script as a directive:
114 #PBS -l nodes=15,walltime=2:00:00
116 qsub -l cput=1:00:00,walltime=2:00:00,file=50gb,mem=15mb script
119 qalter -lcput=30:00,pmem=8mb 123.jobid
120 or in a qsub script as a directive:
122 #PBS -l cput=1:00:00,walltime=2:00:00,file=50gb,mem=15mb
124
126 The resource values take the following units:
127 time specifies a maximum time period the resource can be used. Time
129 is expressed in seconds as an integer, or in the form:
130 [[hours:]minutes:]seconds[.milliseconds]
131 size specifies the maximum amount in terms of bytes or words. It is
133 expressed in the form integer[suffix] The suffix is a multi‐
134 plier defined in the following table, The size of a word is the
135 word size on the execution host.
136 b or w bytes or words.
138 kb or kw Kilo (1024) bytes or words.
140 mb or mw Mega (1,048,576) bytes or words.
142 gb or gw Giga (1,073,741,824) bytes or words.
144 unitary The maximum amount of a resource which is expressed as a simple
146 integer.
