Hollo, I asked Ralph to re-enable cpus-per-proc of openmpi-1.7.x one year ago.
According to Ticket #3350, it shows "(closed defect: fixed)". So I tried latest openmpi-1.7.3, but I find that -cpus-per-proc is still not accepted like bellow. mpirun -np 4 -x OMP_NUM_THREADS=2 -cpus-per-proc 2 -report-bindings MyProg mpirun: Error: unknown option "-p" Type 'mpirun --help' for usage. Do you really fix it? Regards, Tetsuya Mishima
