Compiling the OMPI 1.2.5 tarball should be fine. Can you send the information listed on this page: http://www.open-mpi.org/community/help/ Thanks! On Apr 2, 2008, at 3:05 PM, Danesh Daroui wrote: No I compiled it myself. I don't know what you mean but I have built it from the file open

Danesh, The filesystem physically on the master, specifically including the directory where you are running the open-mpi program, should be NFS mounted by the slave machines. The absolute path name should be the same on all machines. I don't know if that will fix your problem but we had t

You mean I should mount NFS filesystems of slave machine on master so their disks can be accessed from a mount point on master? In that cases, what moint point on master shoud it be? Should I configure open-MPI about this mount point? Can't it work without mounting? I think it should work since

Danesh, Do they all have access to the sam file system/physical hard drive. You will probably need to NFS mount the filesystem on master on the other two systems. Doug Reeder On Apr 1, 2008, at 1:46 PM, Danesh Daroui wrote: Hi all, I have installed Open-MPI on three machine which runs Op

Hi all, I have installed Open-MPI on three machine which runs OpenSUSE and it has been installed successfully. I can submit jobs locally on each machine using "mpirun" and it works fine. I have defined a host file on one of them (master) where I have defined IP address of each machine and numb
