test_multiplication_hermitian fails on hohgant

Thanks @rasolca for checking. The only thing that stands out is that the stacktrace is relatively long, but not impossibly so. It _may_ be that it's running out of stack...

test_multiplication_hermitian fails on hohgant

I haven't tried again after the nvidia nodes were returned to hohgant but I'll try to do so this week. @RMeli or @albestro has either of you run tests on...

test_multiplication_hermitian fails on hohgant

This is still a problem but I don't know what's causing it.

Make choice of managed or unmanaged communicators explicit

I think I didn't do anything about this at all yet. The default is still unmanaged.

Replace `threadmanager::wait` by moving blocking MPI communication to separate `std::thread`

Before doing this I would like to have something like https://github.com/pika-org/pika/issues/167 in pika. This would allow doing it relatively cleanly with ``` pika::this_thread::sync_wait( execution::schedule( execution::std_thread_scheduler{}) | execution::then(blocking_mpi_functions_go_here)); ```

Some unit tests are too slow

I agree with the tests taking very long to finish. There may be multiple reasons for it, but I wonder if one of them is simply oversubscription. I think most...

Some unit tests are too slow

Do we have a way to restrict a unit test to only use e.g. 4 ranks (for your case of 8 cores), or similar?
