Hi Ralph, That solves the several mtt failures involving collective and intercommunicators (allgather_inter and friends), that occured when running with --mca mpi_procs_cutoff 0. I could reproduce the issue with 8 tasks or more and two nodes (Not sure two nodes matter here...) In this case

Hi Ralph, That solves the multiple mtt failures that occurred with inter communicators and mpi_procs_cutoff. You can reproduce this with allgather_inter from ibm/collective, --mca mpi_procs_cutoff 0, 8 tasks and two nodes. Basically, a proc_list[i] can be a sentinel, so it is not always correct

Hi Gilles Could you please explain this one - I honestly don’t understand the change, and haven’t encountered a problem. Thanks Ralph > On Jan 5, 2016, at 11:22 PM, git...@crest.iu.edu wrote: > > This is an automated email from the git hooks/post-receive script. It was > generated because a
