I don't know how you change your RQS, but it can also be done on the command
line while it's not explained in detail in the man page:
$ qconf -srqs
{
name foo
description Demo
enabled FALSE
limit name special users {reuti} to slots=20
limit name common users {*} to slots=10
}
$ qconf -mattr resource_quota limit slots=10 foo/special
$ qconf -mattr resource_quota limit slots=5 foo/2
$ qconf -mattr resource_quota enabled true foo
$ qconf -srqs
{
name foo
description Demo
enabled TRUE
limit name special users {reuti} to slots=10
limit name common users {*} to slots=5
}
Also several values can be changed at once:
$ qconf -mattr resource_quota limit h_vmem=1G,slots=25 foo/special
Maybe this way you can write a wrapper which increases the values for the user
in question temporarily and set it back once the job started.
