I know that we are sometimes a little slow to answer user emails, but you need to give us more than a few hours to answer before re-posting your mails. :-) If you want to see if there are easy fixes to why 1.4.x and/or 1.6.x fail to compile, see this page: http://www.open-mpi.org/community/help/ Send all the info listed on that page. > how I can check if the installation works, prior to configure the cluster See: http://www.open-mpi.org/community/lists/users/2012/03/18846.php We say something quite similar in the (1.6.x) README file: When verifying a new Open MPI installation, we recommend running three tests: ----- 1. Use "mpirun" to launch a non-MPI program (e.g., hostname or uptime) across multiple nodes. 2. Use "mpirun" to launch a trivial MPI program that does no MPI communication (e.g., the hello_c program in the examples/ directory in the Open MPI distribution). 3. Use "mpirun" to launch a trivial MPI program that sends and receives a few MPI messages (e.g., the ring_c program in the examples/ directory in the Open MPI distribution). If you can run all three of these tests successfully, that is a good indication that Open MPI built and installed properly. ----- > Also, it will be ok if I copy the openmpi-1.2.9 directory to the other > nodes? The installation took like almost 3 hours. Wow; configuration / compilation of Open MPI took *3 hours*? I'm guessing you have very old / low-power processors, or very slow network filesystem access...?
