[mpich-discuss] Volatile nodes

[Hiatt, Dave M]

No, I was thinking more of a case where a node does MPI::Init, communicates information, does an MPI::Finalize, then returns later with another MPI::Init and MPI::Finalize pair on and off.  The node would be part of a communicator that isn't part of the primary calculation but more on the idea of a monitor.

Do you mean what happens if one of the nodes crashes? The current version of
MPICH2 will abort in that case, but within the next year we plan to have a
version that is more resilient to such failure; i.e., it won't abort, but
any attempt to communicate with that node will return an error.
