Hi Ralph,



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.

why not?

export OMPI_Magic_Variavle="-x LD_LIBRARY_PATH -x PATH"
cold be possible, or not?

That is basically what I had in mind, but it now requires that we parse it. My point was that you can't do

export OMPI_dash_x="foo"
export OMPI_dash_x="bar"

like you would do on the cmd line itself, so now there has to be a special parser for handling the envar separate from the cmd line entry.

Not a big deal - just takes some code...which is why it isn't an immediate response.




I can add it to the "to-do" list for a rainy day :-)
That would be great :-)

Thanks for your help!

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
