Hello, I hope this is a quick question.
The way I read the man page (srun/sbatch), I should be allowed a request like --constraint="broadwell|haswell" to get either a broadwell or a haswell node, or not? (I mean yes, assuming nodes with that feature exists). I can't get that to work; when I try, I get this: srun -C "broadwell|haswell" --pty /bin/bash srun: error: Unable to allocate resources: Invalid KNL configuration (MCDRAM or NUMA option) Both 'srun -C "broadwell" .... and 'srun -C "haswell" ...' work, i.e. I can request either a broadwell or a haswell node. I can get the '&' operator to work just fine - e.g. srun -C "broadwell&E5-2640v4" --pty /bin/bash works as expected. So what am I doing wrong with the 'or'? This is slurm 17.11.8, btw. (And yes, I have the 'knl_generic' plugin enabled; there were some KNL nodes, although they are no longer there. Still, I'm not even requesting 'knl' here?) Google didn't really yield anything, so I thought asking might be quicker. Thanks!
