LIke before: can you compile and run mpihello.c this time – all as ordinary user in case you installed the Open MPI into something like $HOME/local/openmpi-2.1.1 and set paths accordingly. There is no need to be root to install a personal Open MPI version in your home directory. -- Reuti > > Thanks and kind regards. > Tim > > On 22 May 2017 at 19:39, Reuti <re...@staff.uni-marburg.de> wrote: > Hi, > > > Am 22.05.2017 um 07:22 schrieb Tim Jim <timothy.m....@gmail.com>: > > > > Hello, > > > > Thanks for your message.
