Ability to run inverse operations multithreaded #44

Closed paddyroddy closed 3 years ago

paddyroddy commented 3 years ago

See this question https://stackoverflow.com/q/65044164/7359333 basically I'm able to run my tasks using multiprocessing but ideally would like to use a multithreaded solution.

The problem is related to FFTW www.fftw.org/fftw2_doc/fftw_3.html#SEC46. Is there a way we can force some calls to act single threaded?

This should now work with version 1.4 and the ducc0 backend. Just pass the desired number of threads using the nthreads parameter!

Thanks @mreineck (closing issue).

P.S. Have been a little busy last few days but will get back to your comments on other issues/PRs soon...
