On the trunk, I am seeing failures of the ibm tests iallgather and iallgather_in_place. Is this a known issue?
$ mpirun --mca btl self,sm,tcp --mca coll ml,basic,libnbc --host drossetti-ivy0,drossetti-ivy0,drossetti-ivy1,drossetti-ivy1 -np 4 iallgather [**ERROR**]: MPI_COMM_WORLD rank 0, file iallgather.c:77: bad answer (0) at index 1 of 4 (should be 1) [**ERROR**]: MPI_COMM_WORLD rank 1, file iallgather.c:77: bad answer (0) at index 1 of 4 (should be 1) Interestingly, there is an MCA param to disable it in coll ml which allows the test to pass. $ mpirun --mca coll_ml_disable_allgather 1 --mca btl self,sm,tcp --mca coll ml,basic,libnbc --host drossetti-ivy0,drossetti-ivy0,drossetti-ivy1,drossetti-ivy1 -np 4 iallgather $ echo $? 0 ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
