Hi all I am getting an error (details follow) in the simplest of the possible test scenarios: Two identical regular Dell PCs connected back-to-back via an ethernet switch on the 10/100 ethernet. Both run Fedora Core 4. Identical version ( 1.1) of Open MPI is compiled and installed on both of them *without* a --prefix option ( i.e. installed on the default location of /usr/local). The hostfile on both the machine is the same: cat ~/hostfile 192.168.22.29 192.168.22.103 I can run openMPI on either of these two machines by forking two processes: mpirun -np2 osu_acc_latency <------ This runs fine on either of the two machines. However, when I try to luch the same program across the two machines, I get an error: mpirun --hostfile ~/hostfile -np2 /home/durga/openmpi-1.1 /osu_benchmarks/osu_acc_latency durga@192.168.22.29's <durga@192.168.22.29%27s> password: foobar /home/durga/openmpi-1.1/osu_benchmarks/osu_acc_latency: error while loading shared libraries: libmpi.so.0: cannot open shared object file: No such file or directory. However, the file *does exist* in /usr/local/lib: ls -l /usr/local/lib/libmpi.so.0 libmpi.so.0 -> libmpi.so.0.0.0 I have also tried adding /usr/local/lib to my LD_LIBRARY_PATH on *both* machines, to no avail.
first of: I'm not from the openMPI team. Where did you add your LD_LIBRARY_PATH ? make shure it is in one of the profile files for your shell.. such has: .bash_profile and _not_ .bashrc that's a tipical error in these kind of configurations.. best regards Any help is greatly appreciated.
