Parallel Cholesky solve

Hello everyone.
I have created a matrix of type MATMPIAIJ and I want to perform Cholesky factorization on it in order to solve a linear system.
I have downloaded the Pastix package and I use MAT_SOLVER_PASTIX as an argument to MatGetFactor() but I get the following error message:

"No support for this operation for this object type!
Cannot use PETSc AIJ matrices with PaStiX Cholesky, use SBAIJ matrix!"

Is there a way to use parralel Cholesky factorization with MATMPIAIJ type instead of SBAIJ?
