Note the following still indicates that "--bind-to none" is the default:
-bash-4.2$ mpirun --help | grep -A2 'bind-to '
--bind-to <arg0> Policy for binding processes [none (default) |
hwthread | core | socket | numa | board] (supported
qualifiers: overload-allowed,if-supported)
However, Jeff has clearly stated (
http://www.open-mpi.org/community/lists/devel/2013/12/13456.php) that
bind-to-core is to be the default in 1.7.4.
The --map-by and --rank-by outputs are similarly out-dated:
-bash-4.2$ mpirun --help | grep -A1 'map-by '
--map-by <arg0> Mapping Policy [slot (default) | hwthread | core |
socket | numa | board | node]
-bash-4.2$ mpirun --help | grep -A1 'rank-by '
--rank-by <arg0> Ranking Policy [slot (default) | hwthread | core |
socket | numa | board | node]
