LSF Version 7.3 - Platform LSF Configuration Reference

•
A single user (specify user_name). To specify a Windows user account, include the
domain name in uppercase letters (DOMAIN_NAME\user_name).
•
Users in a group, individually (specify group_name@) or collectively (specify
group_name). To specify a Windows user group, include the domain name in uppercase
letters (DOMAIN_NAME\group_name).
•
Users not included in any other share assignment, individually (specify the keyword
default) or collectively (specify the keyword others)
•
By default, when resources are assigned collectively to a group, the group members
compete for the resources on a first-come, first-served (FCFS) basis. You can use
hierarchical fairshare to further divide the shares among the group members.
•
When resources are assigned to members of a group individually, the share
assignment is recursive. Members of the group and of all subgroups always compete
for the resources according to FCFS scheduling, regardless of hierarchical fairshare
policies.
•
number_shares
•
Specify a positive integer representing the number of shares of the cluster resources
assigned to the user.
•
The number of shares assigned to each user is only meaningful when you compare it
to the shares assigned to other users or to the total number of shares. The total number
of shares is just the sum of all the shares assigned in each share assignment.
Description
Enables queue-level user-based fairshare and specifies share assignments. Only users with
share assignments can submit jobs to the queue.
Compatibility
Do not configure hosts in a cluster to use fairshare at both queue and host levels. However,
you can configure user-based fairshare and queue-based fairshare together.
Default
Not defined. No fairshare.
FAIRSHARE_QUEUES
Syntax
FAIRSHARE_QUEUES=queue_name[queue_name ...]
Description
Defines cross-queue fairshare. When this parameter is defined:
•
The queue in which this parameter is defined becomes the “master queue”.
•
Queues listed with this parameter are “slave queues” and inherit the fairshare policy of the
master queue.
•
A user has the same priority across the master and slave queues. If the same user submits
several jobs to these queues, user priority is calculated by taking into account all the jobs
the user has submitted across the master-slave set.
