Comment (by Roland Haas):

This has been confirmed. @Erik Schnetter and @Roland Haas have access to Cori. My own guess is that this is a fallout of NERSC switching to SLURM (https://www.nersc.gov/assets/Uploads/SLURM-NUG-Nov2015.pdf) which counts each hyperthread as a cpu so the --procs 64 being translated into --mppwidth 64 is translated into the wrong number nodes by the PBS -> SLURM translation at NERSC. See https://docs.nersc.gov/jobs/examples/#hybrid-mpiopenmp-jobs .
