Hi Ralph,
OK, that's pretty much what I thought but wanted to get a sanity check. :-)
I'll see if I can reproduce the issue in a more precise manner and open an
issue if I find something off in the mapping.
Thanks,

Please re-read my prior email (MCA parameters are not always set as environment
variables):
https://www.mail-archive.com/devel@lists.open-mpi.org/msg19958.html
If you want to read the value of MCA parameters in MPI applications, you should
be using the MPI_T API. That will work regardless o
Hi,
We're trying to track down some curious behavior and decided to take a step
back and check a base assumption.
When running within a managed environment (job allocation):
Q: Should you be able to use `--hostfile` or `--host` options to
operate on a subset of the resources in the a
Basically, I like to set apath in the param conf file, and let OMPI broadcast
it to each MPI rank.
In the following example, it prints the value as NULL, if I just set it in the
conf file. So My question is how to update some ompi base code to make it right?
If I set it in mpirun -mca apath=s
It's still not clear what you're trying to do.
Are you setting an MCA parameter, or are you trying to forward arbitrary
environment variables? Are you working in MPI processes (or executables
launched by MPI processes), or in the Open MPI code base itself?
Also, Ralph and I chatted: what he sa
I need this parameter used in my other codes related to ompi,
do I need to register "OMPI_MCA_apath" in some codes in OMPI? if so, usually in
which codes?

I think Jeff got lost in the weeds here. If you define a new MCA param in the
default param file, we will automatically pick it up and it will be in the
environment of your application. You don’t need to do anything. However, you
checked for the wrong envar. Anything you provide is going to have

I mean getenv("OMPI_MCA_apath") in setup_fork.

oops, I should use the word "MCA parameters". If I define a MCA parameter
(apath, for example) in etc/openmpi-mca-params.conf, how can function
setup_fork in ompi/orte/mca/schizo/ompi/schizo_ompi.c get its value? I tried
to call getenv("apath") there, which return null.
However, If I defined i

I'm not quite sure what you're asking. The openmpi-mca-params.conf does no
That's pretty cool!
One minor request: our project's name is "Open MPI", not "OpenMPI". Could you
update your listings to reflect the correct name?
Thank you!
