Couldn't it be that the slot list should be 0,1,2,3?
It depends on the setup.
You can get some more information about _what it does_ by using
--report-bindings (when/if it succeeds).

I'm trying to run a multi-node job but I want to map all of the

I'm having a hard time figuring out how to do this, the obvious
combinations
mpirun -n 8 -npernode 4 -report-bindings ...
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
