[petsc-users] code hangs inside SUPERLU DIST

[Wen Jiang]

Hello Everyone,

I am using KSPPRECONLY type ksp with SUPERLU DIST. However, I found my code
hangs inside superlu_dist solver and never finishes.

The problem I am solving is a time-dependent nonlinear pde and I use fully
Newton-Raphson for each time step. So my code will look like,

For Time STEP = start to end

    For Newton-Raphson Iterations = 1 to max iterations

        Calculate Matrix A;



    END Newton-Raphson Iterations

End Time STEP


Could you give me any hints what the problem might be? I am using Petsc 3.1
p8 and superlu dist v2.4.
