[Body]
== Description ==
Matrix multiplication is a binary operation that takes a pair of matrices and produces another matrix.

If A is an n×m matrix and B is an m×p matrix, the result AB of their multiplication is an n×p matrix
defined only if the number of columns m in A is equal to the number of rows m in B. When multiplying
A and B, the elements of the rows in A are multiplied with corresponding columns in B.

In this implementation, A and B are square matrices (same number of rows and columns), and so it is the
result matrix C. Each matrix is divided in N blocks of M doubles. The multiplication of two blocks is
done by a multiply task method with a simple three-nested-loop implementation. When executed with COMPSs,
the main program generates N^3^ tasks arranged as N^2^ chains of N tasks in the dependency graph.


== Execution instructions ==
Usage:
runcompss --lang=python src/matmul_objects.py <numberOfBlocks> <blockSize>

where:
        * - numberOfBlocks: Number of blocks inside each matrix
        * - blockSize: Size of each block


== Execution Examples ==
runcompss --lang=python src/matmul_objects.py 16 4
runcompss src/matmul_objects.py 16 4
python -m pycompss src/matmul_objects.py 16 4


== Build ==
No build is required
