Configuring the lsf.shared resource section

About this task

Define configured resources in the Resource section of lsf.shared. There is no distinction between shared and non-shared resources. When optional attributes are not specified, the resource is treated as static and Boolean.

Procedure

Specify a name and description for the resource, using the keywords RESOURCENAME and DESCRIPTION.
Resource names are case sensitive and can be up to 39 characters in length, with the following restrictions:
- Cannot begin with a number
- Cannot contain the following special characters
```
:  .  (  )  [  +  - *  /  !  &  | <  >  @  = ,
```
- Cannot be any of the following reserved names:
```
cpu cpuf io logins ls idle maxmem maxswp maxtmp type model 
status it mem ncpus nprocs ncores nthreads
define_ncpus_cores define_ncpus_procs define_ncpus_threads
ndisks pg r15m r15s r1m swap swp tmp ut local
dchost jobvm
```
- Cannot begin with inf or nan (uppercase or lowercase). Use -R "defined(infxx)" or -R "defined(nanxx)"instead if required.
- For Solaris machines, the keyword int is reserved and cannot be used.
Optional. Specify optional attributes for the resource.
1. Set the resource type (TYPE = Boolean | String | Numeric). Default is Boolean.
2. For dynamic resources, set the update interval (INTERVAL, in seconds).
3. For numeric resources, set so that a higher value indicates greater load (INCREASING = Y)
4. For numeric shared resources, set so that LSF releases the resource when a job using the resource is suspended (RELEASE = Y).
5. Set resources as consumable in the CONSUMABLE column.
  Static and dynamic numeric resources can be specified as consumable. A non-consumable resource should not be releasable and should be usable in order, select and same sections of a resource requirement string.
  Defaults for built-in indices:
  - The following are consumable: r15s, r1m, r15m, ut, pg, io, ls, it, tmp, swp, mem.
  - All other built-in static resources are not consumable. (For example, ncpus, ndisks, maxmem, maxswp, maxtmp, cpuf, type, model, status, rexpri, server, hname).
  Defaults for external shared resources:
  - All numeric resources are consumable.
  - String and boolean resources are not consumable.
  Note: Non-consumable resources are ignored in rusage sections. LSF rejects resource requirement strings where an rusage section contains a non-consumable resource.
```

```

Run lsinfo -l to view consumable resources.

Resources required for JSDL

The following resources are pre-defined to support the submission of jobs using JSDL files.
