[X10-users] X10 java backend across different nodes

Hello, Can someone tell me how to run an X10 2.0 program on places that reside on different nodes of a cluster? If I use the C++ backend, I should be using a launcher like mpirunx10 -x X10_NTHREADS= -np --hostfile What should I be doing if I am using the JAVA backend? Thanks, Kshitij ---
