Hi Howard, > Could you double check that on the linux box you are using an ompi install > which has java support?
Yes, I have a script file that I call with the Open MPI version that I want to build so that I can't forget to use an empty directory, to remove the last installation before installing the new one, and so on. The strange thing is that I cannot reproduce the error today. I've no idea why it didn't work two days ago. Nevertheless I'm happy that it works now. Thank you very much for your help which forced me to try again. linpc1 java 110 ls -l /usr/local/openmpi-1.9.0_64_gcc/bin/mpijavac lrwxrwxrwx 1 root root 11 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/bin/mpijavac -> mpijavac.pl linpc1 java 111 ls -l /usr/local/openmpi-1.9.0_64_gcc/lib64/*java* -rwxr-xr-x 1 root root 1170 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/libmpi_java.la lrwxrwxrwx 1 root root 20 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/libmpi_java.so -> libmpi_java.so.0.0.0 lrwxrwxrwx 1 root root 20 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/libmpi_java.so.0 -> libmpi_java.so.0.0.0 -rwxr-xr-x 1 root root 538243 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/libmpi_java.so.0.0.0 -rwxr-xr-x 1 root root 1239 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/liboshmem_java.la lrwxrwxrwx 1 root root 23 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/liboshmem_java.so -> liboshmem_java.so.0.0.0 lrwxrwxrwx 1 root root 23 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/liboshmem_java.so.0 -> liboshmem_java.so.0.0.0 -rwxr-xr-x 1 root root 169198 Apr 21 07:52 /usr/local/openmpi-1.9.0_64_gcc/lib64/liboshmem_java.so.0.0.0 linpc1 java 112 tyr fd1026 104 mpiexec -np 6 -host tyr,linpc1,sunpc1 java MatMultWithAnyProc2DarrayIn1DarrayMain You have started 6 processes but I need at most 4 processes.
