  == Why sparse matrices? ==
  
- ScaLAPACK handles only dense and banded matrices for using optimization strategies for High-Performance,
But, Hama will be handles sparse matrices.
-  
   * Sparse matrix operations cannot be optimized, However, Optimization has no value in the
large-scale
   * Also, Optimization algorithms are too complexity
   * Many classes of problems result in matrices with a large number of zeros
