Apparently we can run our tests in parallel just fine. On my local machine this cuts down the runtime from 3 minutes to around 50 seconds with a parallelism of 4: ```sh % for jobs in `seq 1 17`; do printf "--parallel %2d => " "$jobs" && time (ctest --parallel $jobs > /dev/null 2>&1); done --parallel 1 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 41.42s user 9.14s system 27% cpu 3:05.53 total --parallel 2 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 42.55s user 9.16s system 55% cpu 1:33.34 total --parallel 3 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 41.40s user 9.20s system 81% cpu 1:01.79 total --parallel 4 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 42.29s user 9.15s system 102% cpu 49.995 total --parallel 5 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 42.08s user 8.94s system 102% cpu 49.895 total --parallel 6 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 42.51s user 9.33s system 102% cpu 50.590 total --parallel 7 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 43.77s user 9.33s system 105% cpu 50.537 total --parallel 8 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 42.89s user 9.10s system 104% cpu 49.761 total --parallel 9 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 42.77s user 9.19s system 104% cpu 49.810 total --parallel 10 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 44.97s user 9.68s system 107% cpu 50.834 total --parallel 11 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 45.87s user 9.93s system 109% cpu 50.889 total --parallel 12 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 45.37s user 9.33s system 107% cpu 50.908 total --parallel 13 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 45.75s user 9.75s system 108% cpu 50.919 total --parallel 14 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 46.53s user 9.82s system 110% cpu 51.099 total --parallel 15 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 46.76s user 9.81s system 110% cpu 51.379 total --parallel 16 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 47.63s user 9.72s system 114% cpu 50.086 total --parallel 17 => ( ctest --parallel $jobs > /dev/null 2>&1; ) 46.05s user 9.23s system 110% cpu 49.938 total ``` Let's see if this applies to the test runs in CI too.
