- ScaLAPACK handles only dense and banded matrices for using optimization strategies for High-Performance,
But, Hama will be handles both dense/banded and sparse matrices.
+ '''NOTE''' that Sparse matrix operations cannot be optimized.
  
  == Why 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
   * A sparse matrix is a special class of matrix that allows only the non-zero terms to be
stored
   * Reduction in the storage requirements for sparse matrices
