[mpich-discuss] MPI process killed and SIGUSR1

Hi Wesley,



Suppose my server-client connection is setup using MPI_Comm_accept/MPI_Comm_connect.

Now one of the clients dies.

If the server sends a non-blocking message to the dead client by MPI_Isend, will MPI_Wait guaranteed to return Error code?



Thanks,

Hirak
