[petsc-dev] CHOLESKY with MUMPS doesn't work properly

[Alexander Grayver]

Hong,

I configured PETSc from scratch and now it works, thanks.

BTW, in MUMPS after factorization I can get scaling vector  (MUMPS 
scales matrix before factorization) easily mumid%ROWSCA.
This scaling vector was useful for me because of some kind of analysis. 
Would it be possible to get it through PETSc somehow?

Regards,
Alexander
