[mpich2-dev] Parent terminates when the spawned child terminates

[Suraj Prabhakaran]

Hello,

By default, when a spawned child terminates (through exit() or 
mpi_abort() and *NOT* throught MPI_finalize() ), the parent also 
terminates with a message

APPLICATION TERMINATED WITH THE EXIT STRING: Hangup (signal 1)

I am not sure what exactly the standard specifies for such a situation 
but it kind of defeats the purpose of parent-child relationship. I would 
be glad to know if there is any specific reason why it is implemented 
this way and why it should stay this way. If there is no specific 
reason, may I request that a work around for this is implemented?

Thanks,
Suraj Prabhakaran
