The pithy ruminations from Oren Mustaki on
<[gridengine users] preventing mix between 2 hosts group> were:
=>
=> Hi everybody
=>
=> i have 2 groups of 36 nodes each. each group is connected via Infiniband
=> switch.
=> the 2 Infiniband switches are *not* connected.
=>
=> the groups are:
=> par.q@@group1 , par.q@@group2
=>
=> the -q line:
=> #$ -q par.q@@group1,par.q@@group2
=>
=> once in a while a job is trying to run on nodes from both groups which
=> result in failure.
=>
=> is there a way to allow running on par.q@@group1 or par.q@@group2 but never
=> on both ?
You could:
put both groups into the same queue
assign a boolean attribute to each group (for example,
each server in "group1" has the attribute "group1")
The submission would look like:
qsub -q combined_groups -l group1 myjob
or
qsub -q combined_groups -l group2 myjob
Without specifying the resource requirement, the job would be free to run in
either group, a benefit for things like single-slot jobs, as in:
