Hi,<br><br>Is there any way to exclude a dead process from communicator? I was trying to use MPI_Comm_split hoping to construct a new Comm with alive process leaving the dead process alone. But it looks like it is collective operation and it halted saying process in local group is dead. Is it really possible to exclude dead process &amp; create a new Comm with healty processes. Any suggestion/help appreciated.
<br><br>Thanks in advance<br>
