I am trying to run a FORTRAN program on stampede (xsede machine). The error message I am getting is 'heap maxed out'. I think it has something to do with virtual memory allocation. So I use the following command to allocate more threads to my process export OMP_NUM_THREADS=100But still I am getting the same error message. Can anyone help me to solve this?Thanks!
