Hi, I've installed mpich-v3.2.1 into my cluster but I am having problems. My MPICH installation is configured with the gfortran compiler. Although I can compile my parallel program with no errors, I can not run it. Below is the error message I get. Would you please help me with this problem. I also added the following lines to my /etc/environment and .bashrc file export PATH=/clusterfiles/mpich2/bin:$PATH and LD_LIBRARY_PATH=/clusterfiles/mpich2/lib:$LD_LIBRARY_PATH $ mpiexec -f machines -launcher rsh -n 2 ./a.out ./a.out: error while loading shared libraries: libgfortran.so.3: cannot open shared object file: No such file or directory libgfortran.so.3 does reside on my computer just not in my nfs'ed "/clusterfiles/mpich2/lib" Please find attached my c.txt, m.txt and mi.txt files I appreciate any clues you might have. Thanks and cheers, Bill _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
