Hi Rolf, This may be related to change set 32659. If you back this change out, do the tests pass? Howard From: devel [mailto:devel-boun...@open-mpi.org] On Behalf Of Rolf vandeVaart Sent: Monday, September 15, 2014 8:55 AM To: de...@open-mpi.org<mailto:de...@open-mpi.org> Subject: [OMPI devel] coll ml error with some nonblocking collectives I wonder if anyone else is seeing this failure. Not sure when this started but it is only on the trunk. Here is a link to my failures as well as an example below that.
