any examples to demonstrate how to Spooles package?

[Yujie]

Dear Sanjay:

Thank you for your reply. I don't understand what you said. Now, I want to
use spooles package to inverse a sparse SPD matrix. I have further checked
the inferface about spooles in PETSc. I find although spooles can deal with
AX=B (B may be a dense matrix) with parallel LU factorization.
However, PETSc only provide the following:
51: PetscErrorCode MatSolve_MPISpooles(Mat A,Vec b,Vec x)
I don't set b to a matrix even if I use
178: PetscErrorCode MatFactorNumeric_MPISpooles(Mat A,MatFactorInfo
*info,Mat *F) for LU factorization.

Could you have any suggestions about this? thanks a lot.

Regards,
Yujie
