Hi Ralph,
Thanks for taking time to look into my problem. As you can see , it
happens when i dont have both exe available on both nodes.
When it's the case (test3) , it works. I dont know if my particular
libdir causes the problem or not but I 'll try on Monday with a more
classical setup.
I ll keep you inform.

HI Geoffrey
Hmmm....well, I redid my tests to mirror yours, and still cannot
replicate this problem. I tried it with both slurm and ssh
environments - no difference in the results.
% make hello
% cp hello hello2
% ls
hello hello2
% mpirun -n 1 -host odin038 ./hello : -n 1 -host odin039 ./hello2
Hello World, I am 0 of 2
Hello World, I am 1 of 2
I have tried a variety of combinations, including giving a fake
executable as one of the apps, and have not been able to replicate
your observed behavior. In all cases, it works correctly.
It looks like you are using rsh/ssh as you launch environment. All I
can advise at this stage is to again check to ensure that
the .login/.cshrc (or whatever) on your remote nodes isn't setting
your path to point at another OMPI installation. The fact that you can
run at all would seem to indicate that things are okay, but I honestly
have no ideas at this stage as to why you are seeing this behavior.
Sorry I can't be of more help...
