[petsc-users] MatPtAP for involving MPIDENSE and MPIAIJ matrices

I'm trying to evaluate B = P^T * A * P, where P is an MPIDENSE matrix and A
is an MPIAIJ matrix. Neither MatTransposeMatMult nor MatPtAP support such
an operation for the given type of matrices. I tried to look into
MATELEMENTAL class and didn't find any MatTransposeMatMult function for a
pair of Elemental matrices.

What would be a possible and efficient way to perform such the above
