DESCRIPTION

9       This  page  summarizes  the  resources supported by PBS for IBM systems
10       running AIX version 5.  These resources are specified for jobs  by  in‐
11       cluding them in the -l option argument on the qsub or qalter command or
12       in the PBS job script.

RESOURCES

15       cput      Maximum amount of CPU time used by all processes in the  job.
16                 Units: time.
17
18       file      The  largest  size  of any single file that may be created by
19                 the job.  Units: size.
20
21       mem       Maximum amount of physical memory (workingset)  used  by  the
22                 job.  Units: size.
23
24       vmem      Maximum  amount of virtual memory used by all concurrent pro‐
25                 cesses in the job.  Units: size.
26
27       nice      The nice value under which the job is to be run.  Units: uni‐
28                 tary.
29
30       pcput     Maximum  amount of CPU time used by any single process in the
31                 job.  Units: time.
32
33       pmem      Maximum amount of physical memory (workingset)  used  by  any
34                 single process of the job.  Units: size.

36       pvmem     Maximum  amount  of virtual memory used by any single process
37                 in the job.  Units: size.
38
39       walltime  Maximum amount of real time during which the job  can  be  in
40                 the running state.  Units: time.
41
42       arch      Specifies  the  administrator defined system architecture re‐
43                 quried.  This defaults to whatever the PBS_MACH string is set
44                 to in "local.mk".  Units: string.
45
46       host      Name  of  host  on which job should be run.  This resource is
47                 provided for use by the site's scheduling policy.    The  al‐
48                 lowable values and effect on job placement is site dependent.
49                 Units: string.
50
51       nodes     Number and/or type of nodes to be reserved for exclusive  use
52                 by  the job.  The value is one or more node_specs joined with
53                 the '+' character, "node_spec[+node_spec...].  Each node_spec
54                 is  an  number  of nodes required of the type declared in the
55                 node_spec and a name or one or more  property  or  properties
56                 desired  for the nodes.  The number, the name, and each prop‐
57                 erty in the node_spec are separated by a colon  ':'.   If  no
58                 number is specified, one (1) is assumed.  Units: string.
59
60                 The  name of a node is its hostname.  The properties of nodes
61                 are:
62
63                 . ppn=# specifying the number  of  processors  per  node  re‐
64                   quested.  Defaults to 1.
65
66                 . arbitrary  string  assigned  by  the  system administrator,
67                   please check with your administrator as to the  node  names
68                   and properties available to you.
69
70                 Examples:
71
72                 . To ask for 12 nodes of any type: -l nodes=12
73
74                 . To  ask for 2 "server" nodes and 14 other nodes (a total of
75                   16): -l nodes=2:server+14
76                   The above consist of two node_specs "2:server" and "14".
77
78                 . To ask for (a) 1 node that is a "server" and has a  "hippi"
79                   interface,  (b)  10  nodes  that are not servers, and (c) 3
80                   nodes that have a large amount of memory an have hippi:
81                   -l nodes=server:hippi+10:noserver+3:bigmem:hippi
82
83                 . To ask for three nodes by name:
84                   -l nodes=b2005+b1803+b1813
85
86                 . To ask for 2 processors on each of four nodes:
87                   -l nodes=4:ppn=2
88
89                 . To ask for 4 processors on one node:
90                   -l nodes=1:ppn=4
91
92                 . To ask for 2 processors on each of two blue nodes and three
93                   processors on one red node:
94                   -l nodes=2:blue:ppn=2+red:ppn=3
95
96       host      Allows  a  user  to  specify  the desired execution location.
97                 This resource is provided for use by  the  site's  scheduling
98                 policy.   The allowable values and effect on job placement is
99                 site dependent.  Units: string.
100
101       other     Allows a user to specify site specific information.  This re‐
102                 source  is  provided for use by the site's scheduling policy.
103                 The allowable values and effect on job placement is site  de‐
104                 pendent.  Units: string.
105
106       software  Allows a user to specify software required by the job.   This
107                 is useful if certain software packages are only available  on
108                 certain  systems  in the site.  This resource is provided for
109                 use by the site's scheduling policy.   The  allowable  values
110                 and  effect  on  job  placement  is  site  dependent.  Units:
111                 string.

RESOURCE UNITS

129       The resource values take the following units:
130
131       time    specifies a maximum time period the resource can be used.  Time
132               is expressed in seconds as an integer, or in the form:
133               [[hours:]minutes:]seconds[.milliseconds]
134
135       size    specifies the maximum amount in terms of bytes or words.  It is
136               expressed in the form integer[suffix] The suffix  is  a  multi‐
137               plier defined in the following table, The size of a word is the
138               word size on the execution host.
139
140                b or  w    bytes or words.
141
142               kb or kw    Kilo (1024) bytes or words.
143
144               mb or mw    Mega (1,048,576) bytes or words.
145
146               gb or gw    Giga (1,073,741,824) bytes or words.
147
148       unitary The maximum amount of a resource which is expressed as a simple
149               integer.
