Hello All,
Would anyone know why the default mapping scheme is socket for jobs with
more than 2 ranks? Would they be able to please take some time and
explain the reasoning? Please note I am not railing against the
decision, but rather trying to gather as much information about it as I
can so as to be able to better work with my users who are just now
starting to ask questions about it. The FAQ pretty much pushes folks to
the man pages, and the mpirun man page doesn't go in to the reasoning.
Thank you for your time,
David
