Multithreaded operations #42

Open xmusphlkg opened 2 years ago

xmusphlkg commented 2 years ago

Hi, I installed SimInf on my server (2 CPUs, 64 Cores, and 128 threads), but only half the threads worked when running the model. And parallel::detectCores() detected 128 cores. Here is my information: `R version 4.1.2 (2021-11-01) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 19044)

What output do you get from running (SimInf::set_num_threads(NULL))?

Thank you, set_num_threads is helpful in the Intel CPU server, however, the AMD CPU server seems not to help? The model still running on half of the threads (64/128).
