The core counter spans the entire node, not just one socket. So one socket will
have 0,2,4,6 and the other will have 1,3,5,7

I'm trying to run a multi-node job but I want to map all of the
processes to cores on socket #0 only.
I'm having a hard time figuring out how to do this, the obvious combinations
mpirun -n 8 -npernode 4 -report-bindings ...
mpirun -n 8 -npernode 4 --map-by core -report-bindings ...
