[mpich-discuss] Recovering from a Bcast Timeout

[Pavan Balaji]

Calling an init after a finalize in the same program is incorrect as per
the MPI standard. If it worked in some cases, you were lucky :-).

See pg. 291 line 1 of the MPI-2.2 standard.

My question is, will an MPI:: Finalize() followed by and MPI:: Initi() work from the same process.  This error is being caused by our deficient network, we've never lost a blade, and I'm confident both the app and MPI are functioning properly though considerable investigation.
