About threading performance of PARDISO on Xeon CPU

[DreamlikeCastle]

Hi, I am curious about the threading performance of PARDISO on the platform of a lot of CPU cores.

For instance, the PARDISO solver finishes in about 20 seconds to finish on my Xeon 8480 CPU with more than 20 MKL threads, no matter 20, 40, or 50 threads.

Is it limited by RAM bandwidth or other aspects? Could you give any advice on how to continue to improve threading performance? Does the MPI version of the solver behave better?

To use the attached VISUAL STUDIO example, please unzip all 4 files and put the files in one folder.

Thanks in advance.

Hi,

Thanks for posting in Intel Communities.

Could you please let us know the OS, hardware, CPU details, and Intel MKL and Fortran compiler you are using?

Could you please provide us with the complete output you getting while running the code?
