Hi Jeff,
FWIW, environment variables prefixed with "OMPI_" will automatically be distributed out to processes.
Of course, but saddingly the variable(s) we want to ditribute aren't "OMPI_" variable.
Depending on your environment and launcher, your entire environment may be copied out to all the processes, anyway (rsh does not, but environments like SLURM do), making the OMPI_* and -x mechanisms somewhat redundant.Does this help?
By now I specified the $MPIEXEC variable to "mpiexec -x BLABLABLA" and advice the users to use this. This is a bit ugly, but working workaround. What i wanted to achieve with my mail, was a less ugly solution :o)
Thanks for your help, Paul Kapinos
Not at the moment - though I imagine we could create one. It is a tad tricky in that we allow multiple -x options on the cmd line, but we obviously can't do that with an envar. The most likely solution would be to specify multiple "-x" equivalents by separating them with a comma in the envar. It would take some parsing to make it all work, but not impossible. I can add it to the "to-do" list for a rainy day :-) On Nov 6, 2009, at 7:59 AM, Paul Kapinos wrote: > Dear OpenMPI developer, > > with the -x option of mpiexec there is a way to distribute > environmnet variables: > > -x <env> Export the specified environment variables to the > remote > nodes before executing the program. > > > Is there an environment variable ( OMPI_....) with the same meaning? > The writing of environmnet variables on the command line is ugly and > tedious... > > I've searched for this info on OpenMPI web pages for about an hour > and didn't find the ansver :-/ > > > Thanking you in anticipation, > > Paul > > > > > -- > Dipl.-Inform.
