[mpich-discuss] [SPAM] Re: Fw: FAIL of test_primitives in installing of mpich-3.1.2

Run "make testing". If all (or almost all) those tests pass, the MPICH installation is ok. The non-scalability could be for other reasons such as the application code not being suitable for a shared-memory machine.

(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?
