Hello Jeff, Ralph, all!
Meaning that per my output from above, what Paul was trying should have worked, no? I.e., setenv'ing OMPI_<whatever>, and those env vars should magically show up in the launched process.In the -launched process- yes. However, his problem was that they do not show up for the -orteds-, and thus the orteds don't wireup correctly.
Sorry for latency, too many issues on too many area needing improvement :-/ Well, just to clarify the long story about what I have seen:1. got a strange start-up problem (based on bogus configuration of eth0 + known (for you, experts :o) bug in /1.5.x
2. got a workaround for (1.) by setting '-mca oob_tcp_if_include ib0 -mca btl_tcp_if_include ib0' on the command line of mpiexec => WORKS! Many thanks guys!
3. remembered that any MCA Parameters can also be defined over OMP_MCA_... envvars, tried out to set => works NOT, the hang-ups were again here. Checking how the MCA parameters are set by ompi_info - all clear, but doesn't work. My blind guess was, mpiexec does not understood there envvars in this case.
See also http://www.open-mpi.org/community/lists/users/2011/11/17823.phpThus this issue is not about forwarding some or any OMPI_* envvars to the _processes_, but on someone step _before_ (the processes were not started correctly at all in my problem case), as Ralph wrote.
The difference in behaviour if setting parameters on command line or over OMPI_*envvars matters!
