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

[Bill Wichser]

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
