Basic maths.

1 socket per node * 16 cores per socket = 16 CPUs per node

As Ade said, see what Slurmd says it sees.

Also validate it against "nproc" (for total number of cores) and "lscpu"  
output (for more general node config info).

Is this a quad socket box?  Or are you confusing multiple threads per core 
with CPUs?

Best of luck,
Chris
