Hi all,
I`m completely new here so I apologize for my naive question. I have installed openmpi 1.6.4 on my Red Hat Enterprise Linux 6.1 with 8 cores as i`d like to make a 8-core parallel machine for running Gromacs Molecular Dynamics jobs faster. When I run the mpirun -np 8 mdrun command It complains and I face this error: "mpiexec failed: gethostbyname_ex", I searched web and found a post in this forum
exactly in this case by the name Mpd. As I use Red Hat, I could not found exactly the mentioned menu and tabs. Could you please guide me in which menu,tab or file, I can edit the localhost name.
Any help or suggestion would be highly appreciated.
Thanks in advance
