Hi folks,
I. looked for ways to tell to "mpiexec" to forward some environment
variables, I saw a mismatch:
-------------------------------------------------------------------
http://www.open-mpi.org/faq/?category=running#mpirun-options
...
--x <env-variable-names>: A comma-delimited list of environment
variables to export to the parallel application.
-------------------------------------------------------------------
(Open MPI/1.5.3)
$ man mpirun
-x <env>
Export the specified environment variables to the
remote nodes before executing the program. Only one environment
variable can
^^^^^^^^^^^
be specified per -x option.
-------------------------------------------------------------------
So, either the info is outdated somewhre, or -x and --x have different
meaning - but then there is a lack of info, too :o)
Maybe you could update the Wiki and/or the man page?
II. Now the question. Defaultly no non-OpenMPI environmet variables are
exported to the parallel application, AFAIK.
With -x option of mpiexec it is possible to export one (or a list of,
see below) environment variable. But, it's a bit tedious to type a
[long] list of variables.
Is there someone envvar, by setting which to a list of names of other
envvars the same effect could be achieved as by setting -x on command
line of mpirun?
Best wishes
