Hi Ehsan You didn't tell the details of how you configured and installed Open MPI. However, you must point the configuration --prefix to the installation directory, say:
./configure --prefix=/opt/openmpi-1.8.8 In addition, the installation directory must be *different* from the directory where you build Open MPI (say, where you downloaded and decompressed the Open MPI source code tarball). Also, make sure you have writing permissions to both the build and installation directories. If you don't have writing permissions to the installation directory, you may need to use "sudo" or "su" when you do "make install". I hope this helps, Gus Correa On Aug 13, 2015, at 1:29 AM, Ehsan Moradi wrote: > hi, > my dear friends > i tried to upgrade my openmpi version from 1.2.8 to 1.8.8 > but after installing it on different directory "/opt/openmpi-1.8.8/" when i > enter mpirun its version is 1.2.8 > and after installing the directory "/opt/openmpi-1.8.8/" is empty!! > so what should i do for installing and using new version > ???? > my current version was preinstalled on the system and its have a problem with > big jobs i got errno110 (time out), i changed the mac argument to but steel > not working > so if anyone help me to install last version would be a great help. > os: open suse, 4 nodes , > > thanks alot > _______________________________________________ > users mailing list > us...@open-mpi.org > Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/users > Link to this post: > http://www.open-mpi.org/community/lists/users/2015/08/27451.php
