User Section
Platform LSF Reference
468
User Section
Optional. If this section is not defined, all users and user groups can run an unlimited
number of jobs in the cluster.
This section defines the maximum number of jobs a user or user group can run
concurrently in the cluster. This is to avoid situations in which a user occupies all or most
of the system resources while other users’ jobs are waiting.
Structure
Three fields are mandatory: USER_NAME, MAX_JOBS, JL/P.
MAX_PEND_JOBS is optional.
You must specify a dash (
-) to indicate the default value (unlimited) if a user or user
group is specified. Fields cannot be left blank.
Example of a User Section
Begin User
USER_NAME MAX_JOBS JL/P MAX_PEND_JOBS
user1 10 - 1000
user2 4 - -
user3 - - -
groupA 10 1 100000
groupA@ - 1 100
groupC - - 500
default 6 1 10
End User
USER_NAME
User or user group for which job slot limits are defined.
Use the reserved user name
default to specify a job slot limit that applies to each user
and user group not explicitly named. Since the limit specified with the keyword
default applies to user groups also, make sure you select a limit that is high enough,
or explicitly define limits for user groups.
User group names can be the LSF user groups defined previously, and/or UNIX and
Windows user groups.
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.
