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

Hi,
Could you attach testcase of your problem to find out way to speed-up solve part?
with best regards,

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

Hi,
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.
With best regards,

Hi,
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.
With best regards,
