[slurm-users] Running an MPI job across two partitions

[CB]

Hi Andy,

Yes, they are on teh same network fabric.

Sure, creating another partition that encompass all of the nodes of the two
or more partitions would solve the problem.
I am wondering if there are any other ways instead of creating a new
partition?

Thanks,
Chansup
