Problem
Suppose that you have multiple processors, so you can speed up the matrix multiplication. Implement the following method in parallel:
public static double[][] parallelMultiplyMatrix(
double[][] a, double[][] b)
Compose a test program that measures the execution time for multiplying two 2,000 * 2,000 matrices using the parallel and sequential methods, respectively. Make sure to provide a unit of execution time. Explain the code in detail.
