I honestly don’t know if that would work. We do provide a way in the hostfile for someone to specify the username for a remote host, but you’d have to get the ssh system to accept it. Assuming the other username also has your host in its authorized keys, then I suppose it might work - I’ve never tried it myself. > > >>> 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! >> >>> Maxime >>> >>> Le 2015-04-13 09:47, Ralph Castain a écrit : >>>> 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. >>>> >>>> >>>>> On Apr 12, 2015, at 10:33 PM, XingFENG <xingf...@cse.unsw.edu.au> wrote: >>>>> >>>>> 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.
