Thank you.
In our code we have our own linear system solver, optimized for a 
distributed 3 block diagonal matrix.
We are testing its performance against MUMPS and SUPERLU_dist.
We interfaced this solver with PETSc matrix and vector for the left and 
right hand sides of a linear system.
My question: what can I do to make the memory allocated inside the 
solver to be reported by  PetscMemoryGetCurrentUsage?

Thank you,
Michael.
