I am trying to build R4.1.1 with MKL multithreading.We already have in place R3.6.3 using MKL multithreading without any issue .However trying to build new Package using R4.1.1 all went ok hoiwever the Multithreading is not working its like we have only one processor working.
In my case i have R 3.6.3 that was build outside the box using docker and brought to the server because of root restrictions .The mkl is configured on this version and multithreading is working fine see below.
