User group names can be LSF user groups defined previously in this section, or
UNIX and Windows user groups.
◆ all
The reserved name all specifies all users in the cluster.
◆ !
The exclamation mark ! specifies that the group membership should be retrieved
via
egroup.
USER_SHARES
Optional. Enables hierarchical fairshare and defines a share tree for users and user
groups.
By default, when resources are assigned collectively to a group, the group members
compete for the resources according to FCFS scheduling. You can use hierarchical
fairshare to further divide the shares among the group members.
Syntax
([
user, number_shares])
Specify the arguments as follows:
◆ Enclose the list in parentheses, even if you do not specify any user share
assignments.
◆ Enclose each user share assignment in square brackets, as shown.
◆ Separate the list of share assignments with a space.
◆ user
Specify users or user groups. You can assign the shares to:
❖ A single user (specify user_name)
❖ Users in a group, individually (specify group_name@) or collectively (specify
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.
