Users Affected by Multiple Fairshare Policies
Users Affected by Multiple Fairshare Policies
If you belong to multiple user groups, which are controlled by different
fairshare policies, each group probably has a different dynamic share priority
at any given time. By default, if any one of these groups becomes the highest
priority user, you could be the highest priority user in that group, and LSF
would attempt to place your job.
To restrict the number of fairshare policies that will affect your job, submit your
job and specify a single user group that your job will belong to, for the
purposes of fairshare scheduling. LSF will not attempt to dispatch this job
unless the group you specified is the highest priority user. If you become the
highest priority user because of some other share assignment, another one of
your jobs might be dispatched, but not this one.
Submitting a job and specifying a user group
Example
To associate a job with a user group for the purposes of fairshare scheduling,
use bsub -G and specify a group that you belong to. If you use hierarchical
fairshare, you must specify a group that does not contain any subgroups.
User1 shares resources with groupA and groupB. User1 is also a member of
groupA, but not any other groups.
User1 submits a job:
bsub sleep 100
By default, the job could be considered for dispatch if either User1 or GroupA
has highest dynamic share priority.
User1 submits a job and associates the job with GroupA:
bsub -G groupA sleep 100
If User1 is the highest priority user, this job will not be considered.
◆ User1 can only associate the job with a group that he is a member of.
◆ User1 cannot associate the job with his individual user account, because
bsub -G only accepts group names.
