f you don’t specify anything. We deal with this by using job_submit.lua to require users to request at least one type. From: slurm-users on behalf of Kevin Van Workum Reply-To: Slurm User Community List Date: Wednesday, June 20, 2018 at 1:15 PM To: Slurm User Community List Subject: Re: [slurm-

Yes, Boolean constraints do work with minimal configuration. We run mostly MPI jobs on our cluster and want our jobs to run on a single processor type. We assign the processor types as a feature and then the sbatch requests —constraint=[wes|san|has|bro] to run on whatever processor type is free.
