[slurm-users] Lua Job Submit - Setting Features/Constraints

[Kevin Manalo]

Hi Bill and Douglas,

Thanks for your tips -  I narrowed down the issue to the fact that only one partition (a default partition) string is available, in all other cases it is not there, so the condition I'm targeting (job_desc[‘partition’] == "parallel") does not happen, and I don't know the reason for that - I will need to try to reproduce this elsewhere to confirm if it's a bug.

Thanks,
Kevin

    Yes.  We use something like this
    
    
                  if job_desc.features == nil then
                      job_desc.features = "special"
                  else
                      job_desc.features = job_desc.features .. ",special"
                  end
