I have a problem in PARDISO solver in MKL. I want exchange my solver with PARDISO to make the code faster, but sadly the factorization takes a long time. the old multigrid solver is not parallel, so i guess that PARDISO should be faster,but it is not. Do youhave any idea why it is not fast?
I would really appreciate your help.
We would like to help you but we need to have some details about size and type of your matrix, linkline, and processor and so on. Or could you provide testcase with PARDISO to reproduce low performance of this solver on our side to investigate problem deeper?
With best regards,
