mpich - Force MPI to not use network adapter -
i running multi-process calculations using mpich2
argonne national laboratory. run on single machine, -localonly
alternative of mpiexec
used. works.
if network adapter enabled when run starts, , if disable during run, run fails error stating:
op_read error on left context: error = -1 op_read error on parent context: error = -1 unable read cmd header on left context, error = -1 . unable read cmd header on parent context, error = -1 . error posting readv, existing connection forcibly closed remote host.(10054) connection parent broken, aborting. state machine failed.
however, if network adapter disabled when run started, can enable/disable adapter many times want, , run still proceeds end.
is there way run mpiexec
or modify smpd
configuration such mpich2
not using network adapter inter-process communication local runs if adapter available when run starts?
update
the platform windows 7 professional.
the version of mpich2 1.4.1 (32-bit) latest version of mpich2 can find.
as posted on mailing list, you're using old version of mpich. should update newer version of automatically.
update: has been pointed out, on windows, it's not possible update mpich past 1.4.1. beyond that, should utilize either ms-mpi or intel mpi.
