[petsc-dev] How does this compare...

"An Optimized Sparse Approximate Matrix Multiply"
computes  Approximate matrix product for matrices with decay
                   ^^^^^^^^^^^^
  ^^^^^^^^^^
It is for special application in chemistry(?),
not applicable for general sparse matrix product.
No comparison can be drawn to petsc's C=A*B.
