Hallo, When I run my code for a big number of data with Java OpenMPI, I get the error "java.lang.OutOfMemoryError", even if I run that on a server with 64GB RAM. Also I need to maximize the size of the memory allocation. With java I can do that by adding -Xmxn (write man java), but when I run my code I write mpirun -np ... and not java ... . therefore when I use the same command (-Xmxn) with mpirun, I get the error "unknown option -Xmx512m".
So how can I maximize that with OpenMPI? Or is there any other way to do that? Thanks in advance Ibrahim
