Limits for users and
user groups
Jobs are normally queued on a first-come, first-served (FCFS) basis. It is possible
for some users to abuse the system by submitting a large number of jobs; jobs from
other users must wait until these jobs complete. Limiting resources by user prevents
users from monopolizing all the resources.
Users can submit an unlimited number of jobs, but if they have reached their limit
for any resource, the rest of their jobs stay pending, until some of their running jobs
finish or resources become available.
If a limit is specified for a user group, the total amount of a resource used by all users
in that group is counted. If a user is a member of more than one group, each of that
user’s jobs is counted against the limit for all groups to which that user belongs.
Use the keyword
all to configure limits that apply to each user or user group in a
cluster. This is useful if you have a large cluster but only want to exclude a few users
from the limit definition.
Per-user limits on
users and groups
Per-user limits are enforced on each user or individually to each user in the user
group listed. If a user group contains a subgroup, the limit also applies to each
member in the subgroup recursively.
Per-user limits that use the keywords
all apply to each user in a cluster. If user
groups are configured, the limit applies to each member of the user group, not the
group as a whole.
