  2. Languages used MPI, OpenMP, Cilk++, Charm++, Cahpel, X10

  3. Images Generated by running the MPI VErsion 9 size, 3 rows, 3 cols, 5000 threshold 14 size, 2 rows, 2 cols, 0.001 threshold

  4. The Codes Used The MPI code The OpenMP code The Cilk code The Charm++ 2D SOR Module The Charm++ 2D SOR Header File The Charm++ 2D SOR Source File An example of using the Jacobi computation

  5. Timing Numbers used 4 processors, 14 size, 2 rows, 2 cols, 0.001 threshold For MPI Time taken was: 1303255876 seconds and 638772 microseconds For OpenMP Time taken was: 1303256179 seconds and 182009 microseconds (this is currently without executing whole code)
