Intel Phi PARDISO

Dionisis_P_ — Wed, 27 Jan 2016 14:18:10 GMT

Hi,

I am going to run a CFD simulation that the memory usage will be over 100 GB.
I use mkl PARDISO in order to solve the linear system that arises.

Very recently I informed about Intel Phi coprocessor and their capabilities that has.
In order to accelerate the solving, I was wondering if PARDISO incorporates Intel Phi technology internally in order
not to modify my code.

Thank you in advance.

Dionisys, Yes, in MKL version

Dionisys, Yes, in MKL version 11.3 we greatly optimized Pardiso Solver for SMP systems and particaly for Xeon Phi Processor. You may have a look at this KB Article: https://software.intel.com/en-us/articles/significant-scalability-and-performance-improvement-for-intel-mkl-pardiso-on-smp-systems

and try to use Pardiso by himself and let us know the results of your experiments.

you may also have a look at this article ( http://www.scirp.org/journal/PaperInformation.aspx?PaperID=58156 ) where you may see speed up results on Xeon Phi for different stages of Pardiso's computations... all these optimizations are applicable for SMP computations. I hope that helps you to start evaluate this solver on your side.
