[petsc-dev] KSP Viewer problem in petsc3.1

[Gabriele Jost]

Hello!

I am running into a problem when using  petsc  3.1 and SuperLU.

KSP Object:
  type: preonly
  maximum iterations=5000, initial guess is zero
  tolerances:  relative=1e-06, absolute=1e-50, divergence=10000
  left preconditioning
  using PRECONDITIONED norm type for convergence test
PC Object:
  type: lu
    LU: out-of-place factorization
    tolerance for zero pivot 1e-12
    matrix ordering: natural
    factor fill ratio given 0, needed 0
      Factored matrix follows:
        Matrix Object:
          type=mpiaij, rows=13608, cols=13608
          package used to perform factorization: superlu_dist
          total: nonzeros=0, allocated nonzeros=27216
            SuperLU_DIST run parameters:
              Process grid nprow 8 x npcol 8
              Equilibrate matrix TRUE
              Matrix input mode 1
              Replace tiny pivots TRUE
              Use iterative refinement FALSE
              Processors in row 8 col partition 8
              Row permutation LargeDiag

I googled around and found that a similar problem had been reported to the Petsc folks before. The answer was as follows:

Is the patch above included in the SLU that is part of the petsc 3.1 distribution? If not, could we get it?

Thanks so much in advance and best regards,
