about efficiency variation of MKL Pardiso from XE cluster 2020 to intel oneapi in fortran compiler

[xqbc]

I once download a free version of  Intel® Parallel Studio XE Cluster Edition 2020, it showed very good computation ability when I used pardiso with my PC with 2*Intel(R) Xeon(R) CPU E5-2630 v4. The CPU utilization can reached 100%. However, it was expired now. I now used intel oneapi HPC on VS, however, I can only reach 50% cpu utilization when I used Pardiso for solver.  And the computation time is about two times in oneapi than that in cluster 2020. The Fortran project setting is same in both cases, I do not know the problem.

Hi Qibin,

Thanks for posting in Intel communities.

Could you please get back to us with the one API version, the Intel MKL version, a sample reproducer, and steps to reproduce so that it helps us in looking your issue further and assist you accordingly?
