Adds several new mpirun options: * -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding. * -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned. * -bind-to-core - currently the default behavior (maintained from prior default) * -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile Similar features/options are provided at the board level for multi-board nodes. Documentation to follow... This commit was SVN r21791.
