Hi there, I'm an external user of a target library written in C++/OpenMP. The library has its own API and it claims to be thread-safe. Internally, its operations are parallelised with the usual #pragma omp parallel for. I'm deploying it on a server with 40 physical threads and invoking the library from 40 (active) logical threads. This creates 40*40=3600 logical threads in the machine. My question is whether there is a way, as external user of this target library, to limit this insanity so that the OpenMP threads use the resources available in a more composed manner (e.g. worker pool) or should I limit myself to interact with this library from a single logical thread? Thanks in advance, Yours, quaquaraqua -- Quaquaraquà <nuquaquaraqua@xxxxxxxxx>
