I got the matrix and start testing it:

- sequential mumps fails during numerical factorization
[0]PETSC ERROR: [0] MatFactorNumeric_MUMPS line 314 src/mat/impls/aij/ 
[0]PETSC ERROR: [0] MatLUFactorNumeric line 2378 src/mat/interface/ 

- sequential superlu seems hang ...

Something is wrong with your matrix. I'll further check it and let you  
what I get.

How did you get mumps work? Sequential or parallel (num of processors?)?
