Yes, HW identification and task affinity are working as expected. We 
have smt=4, and slurm is able to get it without problems. See output 
from "slurmd -C":

[root at node01 ~]# slurmd -C
NodeName=node01 CPUs=160 Boards=1 SocketsPerBoard=2 CoresPerSocket=20 
ThreadsPerCore=4 RealMemory=583992

Thank you,
