After we defined size and value of first two matrices we used Environment.ProcessorCount to determine number of processors in system. Each processor computes almost equal amount of elements in result matrix.We used method _computeMatrix3() to compute result matrix. -After we defined size and value of first two matrices we used Environment.ProcessorCount to determine number of processors in system.
