Hi, I am still struggling with the installation problems! I get very strange errors. everything is fine when I run OpenMPI for C codes, but when I try to run a simple java code I get very strange error. The code is as simple as the following and I can not get it running:
import mpi.*; class JavaMPI { public static void main(String[] args) throws MPIException { MPI.Init(args); System.out.println("Hello world from rank " + MPI.COMM_WORLD.Rank() + " of " + MPI.COMM_WORLD.Size() ); MPI.Finalize(); } } everything is ok with mpijavac, my java code, etc. when I try to run the code with the following command: /usr/local/bin/mpijavac -d classes JavaMPI.java --> FINE /usr/local/bin/mpirun -np 2 java -cp ./classes JavaMPI --> *ERROR* I'll the following error. Could you please help me about this (As I mentioned the I can run C MPI codes without any problem ).
