Fixes for orterun in handling different MCA params for different
processes (reviewed by Brian):
- By design, if you run the following:
mpirun --mca foo aaa --mca foo bbb a.out
a.out will get a single MCA param for foo with value "aaa,bbb".
- However, if you specify multiple apps with different values for the
same MCA param, you should expect to get the different values for
each app. For example:
mpirun --mca foo aaa a.out : --mca foo bbb b.out
Should yield a.out with a "foo" param with value "aaa" and b.out
with a "foo" param with a value "bbb".
- This did not work -- both a.out and b.out would get a "foo" with
"aaa,bbb".
- This commit fixes this behavior -- now a.out will get aaa and b.out
will get bbb.
- Additionally, if you mix --mca and and app file, you can have
"global" params and per-line-in-the-appfile params. For example:
mpirun --mca foo zzzz --app appfile
where "appfile" contains:
-np 1 --mca bar aaa a.out
-np 1 --mca bar bbb b.out
In this case, a.out will get foo=zzzz and bar=aaa, and b.out will
get foo=zzzz and bar=bbb.
Spiffy.
Ok, fortran build is done... back to Fortran... sigh...
