[petsc-dev] Extend Petsc to uses Pardiso

[Jose David Bermeol]

Hi again, one more question, what should be the difference between MatLUFactorSymbolic and MatLUFactorNumeric?

Thanks

Subject: Extend Petsc to uses Pardiso

Hi, right now I'm trying to extend Petsc to be able to solve linear system of equations(Ax = b) using Pardiso for LU decomposition. So I have a couple of questions:

1. What is the difference between the methods MatSolve and KSPSolve. And in which context should I use each?

2. Should I extend the KSP interface or the Mat interface, or what factors I have to take into account to make my decision?.

For now that would be all.

Thanks
