When defining the nodes in slurm.conf .
For example, we have:
NodeName=DEFAULT Sockets=2 ThreadsPerCore=2 State=UNKNOWN
NodeName=str957-bl0-0[1-2] CoresPerSocket=6 Feature=ib,blade,intel
NodeName=str957-bl0-0[3-5] CoresPerSocket=8 Feature=ib,blade,intel
NodeName=str957-bl0-[15-16] CoresPerSocket=4 Feature=ib,nonblade,intel
NodeName=str957-bl0-[17-18] CoresPerSocket=6 ThreadsPerCore=1
NodeName=str957-bl0-[19-20] Sockets=4 CoresPerSocket=8 ThreadsPerCore=1
NodeName=str957-mtx-[00-15] CoresPerSocket=14 Feature=ib,nonblade,intel

Here, the "Features" are what can be requested by --constraint= line.
