Just out of curiosity... how will OpenMPI start processes under different
accounts ? Through SSH while specifying different user names ?
I am assuming that no resource manager or scheduler will allow this.
I’m assuming he just plans to run the entire job as the other user.
Essentially, it would be the same as if his friend ran the job for him.
From this comment :
My problem is that my account is limited to use 4 machines (I need more
machines to process data). I can borrow my friend's account and thus have
access to another 4 machines but I am not sure whether it works.
I assumed that he wants to run the job under _both_ accounts at the same
time.
My recommendation would be to contact your sysadmin and ask for an exception
instead of going through with this insanity (forgive the judgement here).
Agreed!

Let’s hope you sys admin doesn’t find out about it - they tend to take a dim
view of sharing accounts!
So long as the path and library path are set correctly, we won’t care.

Hi all,
I am wondering if it is possible that MPI programs can be run on machines with
different account?
I am doing experiments with some MPI programs on a cluster. My problem is that
my account is limited to use 4 machines (I need more machines to process data).
I can borrow my friend's account and thus have access to another 4 machines but
I am not sure whether it works.
