The actual job step, in your case the 'sleep' can then run on any node satisfying the condition given via the option '--constraint', so in your case either your Broadwell or you Haswell node. However, I would have thought that, all things being equal, the batch step and the job step would run on the same node. However, I'm not sure how a constrain with 'or' is resolved if multiple solutions are available. What happens if you write the constraint as --constraint="broadwell|haswell" ?
