Windows multithreaded utility that performs matrix multiply

Implement a Windows multithreaded utility that performs matrix multiplication - C code.

- Utility name = Project name = MatrixMult

- Execution will be as follows: MatrixMult C:\[url removed, login to view] C:\[url removed, login to view] C:\[url removed, login to view]

- 2 first arguments – files containing the input matrices A & B in the specified format

- You may assume you have required permissions to access the files

- 3-rd argument – output file to hold the multiplication result in the same format as the input.

- You should override the output file in case it exists.

- In case of an I/O error or content error (such as badly formatted number or != ) you should output an error message and exit with error code 1.

- You may use c-library functions to deal with output, files, memory allocation etc, but the thread creation and manipulation as well as the synchronization must be performed through system calls.

- No external threading libraries (such as TBB, OMP etc.) are allowed.

- Double precision variables (double) should be sufficient for your computations.

- No more than 20 simultaneous threads are allowed

- To show the user that some progress is made, each 100 result cells (in the destination matrix) you should print “.” on the screen

- No new line etc is required just use printf(“.”);

- No more than 50 rows of the destination matrix are to be held in the process memory

- Flush output to the file once you have results (not necessarily 50 rows, you can do earlier but no more than 50)

- The tool should exit immediately upon completion with exit code 0.
