Hi everyone,
I tried LAPACKE_dgels and change NO thread-nubmer settings at all. I guess the default thread number (the same as phycical core number) is used. As I wathch the CPU usage during the code running, it reach a peak at 50 %. I guess that means using 50% of CPU made the calculation run as fast as it could, and using more than 50% of CPU by hyper-threading only slow it down? Do I understand it right here?
