I am trying to switch to OpenMPI, and I ran into a problem : my home
directory must exist on all the nodes, or orted will crash.
I have a "master" machine where I initiate the mpirun command.
Then I have a bunch of slave machines, which will also execute the
MPI job.
My user exists on all the machines, but the home directory is not
mounted on the slaves, so it's only visible on the master node. I can
log on a slave node, but don't have a home there. Of course the
binary I'm running exists on all the machines (not in my home !). And
the problem can be reproduced by running a shell command too, to make
things simpler.
We have thousands of slave nodes and we don't want to mount the
user's homedirs on all the slaves, so a fix would be really really nice.
Example :
I have 3 hosts, master, slave1, slave2. My home directory exists only
on master.
If I log on master and run "mpirun -host master,slave1uname -a" I get
a segfault.
If I log on slave1 and run "mpirun -host slave1,slave2 uname -a", it
runs fine. My home directory does not exist on either slave1 or slave2.
If I log on master and run "mpirun -host master uname -a" it runs
fine. I can run across several master nodes, it's fine too.
So it runs fine if my home directory exists everywhere, or if it does
not exist at all. If it exists only on some nodes and not others,
orted crashes.
I thought it could be related to my environment but I created a new
user with an empty home and it does the same thing. As soon as I
create the homedir on slave1 and slave2 it works fine.
I'm using OpenMPI 1.2.2, here is the error message and the result of
ompi_info.
Short version (rnd04 is the master, r137n001 is a slave node).

I tried to use ssh instead of rsh, it crashes too.
If anyone knows a way to run OpenMPI jobs in this configuration where
the home directory does not exist on all the nodes, it woud really
help !
Or is there a way to fix orted so that it won't crash ?
Here is the crash with -d option :
