https://bugzilla.redhat.com/show_bug.cgi?id=2238263 --- Comment #19 from Cristian Le <fedora@xxxxxxxxx> --- > I'm not sure about the processors - but in the koji build I see: > Tests will run with 3 MPI ranks and 2 OpenMP threads each I have just ran locally `ctest -j 2 -N -V` and it is reporting ``` 19: Test command: /opt/intel/oneapi/mpi/2021.10.0/bin/mpiexec "-n" "8" "./dbcsr_tensor_test" 19: Working Directory: /dbcsr/cmake-build-debug-intel/tests 19: Environment variables: 19: OMP_NUM_THREADS=2 Test #19: dbcsr_tensor_test ``` My `nproc` is 16, and with `ctest -j 2`, it means that it runs 2 mpi jobs at maximum nproc. This is not good because the OS scheduler with have to constantly be switching. Looking at the `%ctest` macro [1], it seems that it does not explicitly adds `-j 2`, so maybe you can specify it for MPI jobs to be `%ctest -j 1`. Alternatively you can manually set `TEST_MPI_RANKS` to `$(nproc)/$TEST_OMP_THREADS/$ctest_jobs`.
