LSF Version 7.3 - Release Notes for Platform LSF

Checkpointing MultiCluster jobs
To enable checkpointing of MultiCluster jobs, define a checkpoint directory in both the send-
jobs and receive-jobs queues (CHKPNT in lsb.queues), or in an application profile
(CHKPNT_DIR, CHKPNT_PERIOD, CHKPNT_INITPERIOD, CHKPNT_METHOD in
lsb.applications) of both submission cluster and execution cluster. LSF uses the directory
specified in the execution cluster.
Checkpointing is not supported if a job runs on a leased host.
Defining consumable resources
Specify resources as consumable in the CONSUMABLE column of the RESOURCE section
of lsf.shared to explicitly control if a resource is consumable. Static and dynamic numeric
resources can be specified as consumable. CONSUMABLE is optional. The defaults for the
consumable attribute are:
•
Built-in indicies:
•
The following are consumable: r15s, r1m, r15m, ut, pg, io, ls, it, tmp, swp, mem.
•
All other built-in static resources are not consumable. (e.g., ncpus, ndisks, maxmem,
maxswp, maxtmp, cpuf, type, model, status, rexpri, server, hname).
•
External shared resources:
•
All numeric resources are consumable.
•
String and boolean resources are not consumable.
You should only specify consumable resources in the rusage section of a resource requirement
string. Non-consumable resources are ignored in rusage sections.
A non-consumable resource should not be releasable. Non-consumable numeric resource
should be able to used in order, select and same sections of a resource requirement string.
When LSF_STRICT_RESREQ=Y in lsf.conf, LSF rejects resource requirement strings
where an rusage section contains a non-consumable resource.
Viewing consumable resources
Use lsfinfo -l to view consumable resources. For example:
lsinfo -l switch
RESOURCE_NAME: switch
DESCRIPTION: Network Switch
TYPE ORDER INTERVAL BUILTIN DYNAMIC RELEASE CONSUMABLE
Numeric Inc 0 No No No No
lsinfo -l specman
RESOURCE_NAME: specman
DESCRIPTION: Specman
TYPE ORDER INTERVAL BUILTIN DYNAMIC RELEASE CONSUMABLE
Numeric Dec 0 No No Yes Yes
Static resources reported by LIM
The resources ncpus, nprocs, ncores, nthreads, maxmem, maxswp, and maxtmp are not static
on UNIX hosts that support dynamic hardware reconfiguration. LIM now reports nprocs,
ncores and nthreads. Use lsinfo to list the resources available in your cluster.
