Java is not magically able to span nodes, you need to ensure your program can handle that and has the necessary supporting infrastructure. *If* your Java app is using MPI via some means then you need to start it with srun, not just run it directly. If you are using Open-MPI for your MPI stack then there is info here: https://www.open-mpi.org/faq/?category=java Good luck, Chris -- Christopher Samuel Senior Systems Administrator Melbourne Bioinformatics - The University of Melbourne Email: [email protected] Phone: +61 (0)3 903 55545
