Shadd, This should be doable with some work. If I were doing this the first thing I’d do do is reconcile all the differences in the slurm.conf of each cluster. Once all the clusters are running with the same settings, or you’ve decided on which cluster’s settings you want to use for the new combined cluster then just append the nodes and partitions from the other clusters into the one slurm.conf to rule them all. Push that file out to all the nodes and restart. As far as multi-OS within a single cluster goes I don’t think that Slurm really cares what OS is running. How you set it up is probably more a matter of what kind of applications you’re running. In a typical HPC cluster running MPI jobs you’re probably going to want to create a separate Slurm partition for each OS. Each job will then be confined to one partition. If you want jobs to be able to run on and communicate between nodes with different OS’s that could be possible, but I’d think that it’ll be a bigger headache than it is worth.
