It's somewhat hard to say without more information. What is your app doing when it calls abort?

Most stuff is working fine but one app is aborting with: MPI_ABORT was invoked on rank 7 in communicator MPI_COMM_WORLD with errorcode 1734831948. The other 23 MPI ranks also abort. I'm a bit confused by the high error code. Does it mean anything specific or should I focus on something else? Thanks. -- Jeff Squyres jsquy...@cisco.com<mailto:jsquy...@cisco.com>
