I have seen this happen in other cray systems when the node-level parallelization is done with openMP instead of MPI. (Or any other thread instead of process level parallelization).

Just wanted to point out that at least one software package is not
being reported correctly.  The NAMD package is being reported as a
running on a single core, which is most likely a batch queuing
error on my application script.  The code does run one process on the
node but that process is multi-cored and heavily utilizes all of the
nodes CPU resources.

The performance clearly indicates full utilization, so I haven't been
quick to spend time working out the clerical error in the batch
system.   Perhaps there are reasons why fixing this should have a higher
priority.

Just adding a data point, not really trying to defend my laziness.  :)
