Example
The following example shows how you can use the various commands for resource quotas. The rule set shown in Example 6–4 defines the following limit:
-
All users together should never take more than 20 slots.
-
All users should take at most 5 slots on all Linux hosts.
-
Every user is restricted to one slot per Linux host except user MyUser who is restricted to two slots, and all other slots on hosts are restricted to 0.
-
The host group @linux includes host1 and host2.
To configure the rule set, use one of the following forms of the qconf command:
-
qconf -arqs <rule-set-name> for each rule set
-
qconf -arqs to run all rule sets at once
After jobs are submitted for different users, the qstat command shows output similar to the example shown in Example 6–5.
Example 6–4 Rule Set
{
name maxujobs
limit users * to slots=20
}
{
name max_linux
limit users * hosts @linux to slots=5
}
{
name max_per_host
limit users MyUser hosts {@linux} to slots=2
limit users {*} hosts {@linux} to slots=1
limit users * hosts * to slots=0
}
Example 6–5 qstat Output
$ qstat
job-ID prior name user state submit/start at queue slots ja-task-ID
