LSF Version 7.3 - Platform LSF Configuration Reference

User group names can be the LSF user groups defined previously, and/or UNIX and Windows
user groups. To specify a Windows user account or user group, include the domain name in
uppercase letters (DOMAIN_NAME\user_name or DOMAIN_NAME\user_group).
Job slot limits apply to a group as a whole. Append the at sign (@) to a group name to make
the job slot limits apply individually to each user in the group. If a group contains a subgroup,
the job slot limit also applies to each member in the subgroup recursively.
If the group contains the keyword all in the user list, the at sign (@) has no effect. To specify
job slot limits for each user in a user group containing all, use the keyword default.
MAX_JOBS
Per-user or per-group job slot limit for the cluster. Total number of job slots that each user or
user group can use in the cluster.
JL/P
Per processor job slot limit per user or user group.
Total number of job slots that each user or user group can use per processor. This job slot limit
is configured per processor so that multiprocessor hosts will automatically run more jobs.
This number can be a fraction such as 0.5, so that it can also serve as a per-host limit. This
number is rounded up to the nearest integer equal to or greater than the total job slot limits
for a host. For example, if JL/P is 0.5, on a 4-CPU multiprocessor host, the user can only use
up to 2 job slots at any time. On a uniprocessor machine, the user can use 1 job slot.
MAX_PEND_JOBS
Per-user or per-group pending job limit. This is the total number of pending job slots that
each user or user group can have in the system. If a user is a member of multiple user groups,
the user’s pending jobs are counted towards the pending job limits of all groups from which
the user has membership.
UserMap section
Optional. Used only in a MultiCluster environment with a non-uniform user name space.
Defines system-level cross-cluster account mapping for users and user groups, which allows
users to submit a job from a local host and run the job as a different user on a remote host.
Both the local and remote clusters must have corresponding user account mappings
configured.
Structure
The following three fields are all required:
•
LOCAL
•
REMOTE
•
DIRECTION
LOCAL
A list of users or user groups in the local cluster. To specify a Windows user account
or user group, include the domain name in uppercase letters (DOMAIN_NAME
