Thanks for the first 2 patches, Tom -- I applied them to the SVN trunk and scheduled them to go into the v1.7 series. I don't know if they'll make 1.7.4 or be pushed to 1.7.5, but they'll get there. I'll defer to Ralph for the rest of the discussion about info keys. On Dec 13, 2013, at 9:16 A

Won't OMPI still automatically pick up env variables that are named beginning with "OMPI_"? On Dec 12, 2013, at 9:47 AM, Ralph Castain wrote: > It would have to be done via MPI_Info arguments, and we never had a request > to do so (and hence, don't define such an argument). It would be easy e

It would have to be done via MPI_Info arguments, and we never had a request to do so (and hence, don't define such an argument). It would be easy enough to do so (look in the ompi/mca/dpm/orte/dpm_orte.c code). MPI implementations generally don't forcibly propagate envars because it is so hard to

Hi all, I'm developing on Open MPI 1.4.5-ubuntu2 on Ubuntu 13.10 (so, Ubuntu's packaged Open MPI) at the moment. I'd like to pass environment variables to processes started via MPI_Comm_spawn. Unfortunately, the MPI 3.0 standard (at least) does not seem to specify a way to do this; thus I have b
