Hi @egio , thank you for raising this important point!

Yes, as far as I can see. There is no global variable / module variable. (BTW, how to test / verify thread safety systematically?)

I have been keeping thread safety in my mind when developing PRIMA. In fact, I asked a [question here about thread safety](https://fortran-lang.discourse.group/t/thread-safety-of-modern-fortran-libraries-what-and-how/2641) some time ago — almost all my posts on this forum arise from PRIMA.
