The fully-vectorial MR-FEM-CSI algorithm has been implemented in C/C++ for distributed memory systems using MPI under the PETSc framework [13].
A major benefit of PETSc is that parallel storage and operations can be transparent to the implementation: once vectors such as [[chi].
Unlike PETSc and Aztec approaches, object-oriented design methodologies are at the basis of the Diffpack project [Bruaset and Langtangen 1997].
7: Iteratively solve the system using either the KSP AGMRES (Algorithm 1) or the PETSc built-in KSP GMRES [41, Algorithm 4].

It is worth noting here that, despite all the different optimization strategies, sparse matrix products are still not standard in sparse libraries such as PETSc [2].
