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?
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.
