Subject: Re: [OMPI users] problems with mpexec/mpirun

I'm afraid you're right... I was testing it with Open MPI on my laptop, but
later on the cluster I had some problems... Probably a colleague has

But I thought the behavior I see might be "implementation-independant".
Probably sounds stupid... :)
Thanks anyway :)
