Dear Rajeev, Thanks for your reply. The time that listed is from runing a forecast of test with WRF(Weather Research and Forecasting ) model. I wonder the FAIL of test_primitives may cause the performance is very poor. Thanks! Yi

If you run "make testing" in the top-level mpich directory, it will run the entire test suite in test/mpi. But those tests don't use as many processes as the number of cores you have listed below. (The number of processes for each test is in the testlist file in each directory under test/mpi.) So what is it that you are running with the different number of cores below?

Dear sir, I installed the mpich-3.1.2 on a machine of IBM X3850 X5 which with 4 Xeon E7-4820 (8 cores, 16 threads) CPU and 64G memory. It has problem of test_primitives in make check.

It uses the mininum amount of time with 8 cores. The following is the time with differernt cores: 60 cores no resuls are out although the executable program is running 56 cores EXIT CODE: 11 Segmentation fault (signal 11) 48 cores 1hour18min 40 cores 1h11m 32 cores 1h9m 24 cores 1h9m 16 cores 1h10m 8 cores 55m 4 cors 1h20m

The log files of inatlling are attached. I'm looking forward to your reply at your earliest convenience.

Sincerely, Yi
