Hi,<DIV>In MKL 10.3 gold solving step of PARDISO could be run in parallel mode, so you now you could decrease working time on solving step phase.</DIV><DIV>With best regards,</DIV><DIV>Alexander Kalinkin</DIV>Wed, 10 Nov 2010 03:13:14 GMTAlexander_K_Intel22010-11-10T03:13:14ZPARDISO solve part speed-up problem

Dear.<BR /><BR /><BR />I've implemented the PARDISO solver into our application.<BR />The process of our application is two parts.<BR />One is reorder, factorization,<BR />and the other one is iterative solve.<BR />The problem is that the solve speed is not fast<BR />than I expected. It is almost same as our old solver.<BR /><BR />If you knowany tips of speed-up for solve part,<BR />please let me know.<BR /><BR />And I wonder whether the solve speed of DSS interface is<BR />faster thanthat of PARDISO interface?<BR /><BR /><BR />B.

Hi,<DIV></DIV><DIV>Could you attach testcase of your problem to find out way to speed-up solve part?</DIV><DIV></DIV><DIV>with best regards,</DIV><DIV>Alexander Kalinkin</DIV>Wed, 11 Aug 2010 05:27:51 GMThttps://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/PARDISO-solve-part-speed-up-problem/m-p/765662#M217Alexander_K_Intel22010-08-11T05:27:51ZPARDISO solve part speed-up problem

DearKalinkin<BR /><BR />There are no data issues, <BR />I mean I just want to know the tips for speed-up.<BR />For example, you may can say "Use the paramA option".<BR />So do you know any tips like that?<BR /><BR />B.

Hi,<DIV></DIV><DIV>Each situation is different from another and there are not common advice. If you use solve step several time I could recommendyou to combine several rhs in one vector and run solve step with many rhs. But as I wrote before maybe such advice doesn'tsuitable in your situation.</DIV><DIV></DIV><DIV>With best regards,</DIV><DIV>Alexander Kalinkin</DIV>Wed, 11 Aug 2010 06:29:57 GMThttps://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/PARDISO-solve-part-speed-up-problem/m-p/765664#M219Alexander_K_Intel22010-08-11T06:29:57ZPARDISO solve part speed-up problem
