Ways to Configure Fairshare
Example
Static priority fairshare
Configuring
A queue is shared by key users and other users. As long as there are jobs from
key users waiting for resources, other users’ jobs will not be dispatched.
1 Define a user group called key_users in lsb.users.
2 Configure fairshare and assign the overwhelming majority of shares to the
critical users:
Begin Queue
QUEUE_NAME = production
FAIRSHARE = USER_SHARES[[key_users@, 2000] [others, 1]]
...
End Queue
Key users have 2000 shares each, while other users together have only 1 share.
This makes it virtually impossible for other users’ jobs to get dispatched unless
none of the users in the key_users group has jobs waiting to run.
If you want the same fairshare policy to apply to jobs from all queues,
configure host partition fairshare in a similar way.
Static priority fairshare assigns resources to the user with the most shares.
Resource usage is ignored.
If 2 users compete for resources, the most important user’s job always runs first.
To implement static priority fairshare, edit lsb.params and set all the
weighting factors used in the dynamic priority formula to 0 (zero).
◆ Set CPU_TIME_FACTOR to 0
◆ Set RUN_TIME_FACTOR to 0
◆ Set RUN_JOB_FACTOR to 0
◆ Set COMMITTED_RUN_TIME_FACTOR to 0
