Shared Memory Matrix Multiplication

Write a parallel program Implement Matrix Multiplication in using pthreads.

• The Sequential Algorithm is discussed in Section 10.2 of your text.
• You should implement the shared memory with up to 8 processes. This number is to be given as a command line argument

The problem should open a data file proj6.dat which has as one number per line.

• The first number n tells you the size of the matrices. For example a 3 would tell you that this is a 3 by 3 matrix
• The next N*N numbers are the values for the first matrix, A.
• The next N*N numbers are the values for the second matrix, B.

Once these have been read in, you are to compute C=A*B

Email report, code, and results to Instructor.

Note: The report should discuss speedup, efficiency, and problems encountered.
