Hmmmm....okay, I can see that. Are you looking for an mca param that
specifies a file that might contain config info we should read when
starting up the orted? What would this local configuration file look
like (e.g., what kind of config directives would you need/want), would
you provide it on the node where mpirun is or would it be on every
remote node, etc?
All things are doable - the devil is in defining the details. :-)

Hi !
thanks for the reply.
On a homeless workers cluster when the workers programs are spawned
via MPI_Comm_spaw{,multiple},
it would be nice to set up a default alternative assumed current
which is local (rather than global
as $HOME) via a local configuration file: you can play with the wdir
in MPI_Info only
if the cluster is homogeneous enough.
hth,

Not currently - could be done if there is a strong enough reason to
do so. Generally, though, the -wdir option seems to do the same
thing. Is there a problem with it, or some need it doesn't satisfy?

Hello List,
in FAQ Running MPI jobs, point 12, we read:
-wdir <directory>: Set the working directory of the started
applications.
If not supplied, the current working directory is assumed
(or $HOME, if the current working directory does not exist on all
nodes).
Is there a way to configure the default alternative assumed
current directory (here $HOME) ?
Thanks in advance,
Jerome
