LSF Version 7.3 - Release Notes for Platform LSF

CONSUMABLE in Resource section—Explicitly controls if a resource is consumable. Applies
to static or dynamic numeric resources. 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.
Environment variables
•
ELIM_ABORT_VALUE—Used when writing an elim executable to test whether the
elim should run on a particular host. If the host does not have or share any of the resources
listed in the environment variable LSF_RESOURCES, your elim should exit with
$ELIM_ABORT_VALUE. When the MELIM finds an elim that exited with
ELIM_ABORT_VALUE, the MELIM marks the elim and does not restart it on that host.
•
LSB_SUCCESS_EXIT_VALUES=[exit_code …] — Specifies the exit values that indicate
successful execution for applications that successfully exit with non-zero values. Use spaces
to separate multiple exit codes. exit_code should be the value between 0 and 255. User-
defined job-level LSB_SUCCESS_EXIT_VALUES overrides application profile level
specification of SUCCESS_EXIT_VALUES in lsb.applications.
•
LSF_MASTER—Set by the LIM to identify the master host. The value is Y on the master
host and N on all other hosts. An elim executable can use this parameter to check the host
on which the elim is currently running.
•
LSF_RESOURCES=dynamic_external_resource_name...—A space-separated list of
dynamic external resources. When the LIM starts a master external load information
manager (MELIM) on a host, the LIM checks the resource mapping defined in the
ResourceMap section of lsf.cluster.cluster_name. Based on the mapping
(default, all, or a host list), the LIM sets LSF_RESOURCES to the list of resources expected
on the host and passes the information to the MELIM. Used when the external load indices
feature is enabled.
New commands
The following new commands have been added to LSF Version 7 Update 3:
brsvmod
Modifies an advance reservation. brsvmod replaces advance reservation option values
previously created, extends or reduces the reservation time window, or adds or removes
reserved hosts of the advance reservation specified by reservation_ID. For a recurring
reservation, can disable specified occurrences of the reservation.
