Subject: [OMPI devel] 1.7.4rc2r30148 - out-of-date mpirun usage output
From: Paul Hargrove (phhargrove_at_[hidden])
Date: 2014-01-08 18:48:31


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]
