ECE 498 AL Machine Problem 2
Tiled Matrix Multiplication

1)  Unzip /home/ac/stratton/498_admin/mps/mp2-tiled-matrixmul.tgz into <sdk>/projects

2)  Edit the source files matrixmul.cu and matrixmul_kernel.cu to complete 
    the functionality of the matrix multiplication on the device.  The two 
    matrices could be any size, but the resulting matrix is guaranteed 
    to have a number of elements such that one CUDA grid will be sufficient 
    to cover the entire output matrix, and input and output matrices will 
    fit in the device memory simultaneously.  

3)  There are several modes of operation for the application.  Note that 
	the file interface has been updated to allow the size of the input 
	matrices to be read.  

    No arguments:  The application will create two randomly sized and initialized 
    matrices such that the matrix operation M * N is valid, and P is 
    properly sized to hold the result.  After the device multiplication is 
    invoked, it will compute the correct solution matrix using the CPU, 
    and compare that solution with the device-computed solution.  If it 
    matches (within a certain tolerance), if will print out "Test PASSED" 
    to the screen before exiting.  

    One argument:  The application will use the random initialization to 
    create the input matrices, and write the device-computed output to the file 
    specified by the argument.  

    Three arguments:  The application will read input matrices from provided files.  
    The first argument should be a file containing three integers.  The first, second 
    and third integers will be used as M.height, M.width, and N.height.  The second 
    and third function arguments will be expected to be files which have exactly 
    enough entries to fill matrices M and N respectively.  No output is 
    written to file.

    Four arguments:  The application will read its inputs from the files provided 
    by the first three arguments as described above, and write its output to the 
    file provided in the fourth.  

    Note that if you wish to use the output of one run of the application as an input, 
    you must delete the first line in the output file, which displays the accuracy of the 
    values within the file.  The value is not relevant for this application.  


4)  To submit your solution, execute the mp2submit.sh script with your netid
and a .tgz file containing your entire submission, including the file
containing the answers to the questions.  

    The .tgz file should contain the mp2-matrixmul folder provided, with all the changes 
    and additions you have made to the source code.  In addition, provide a text file, Word 
    Document, or PDF file with your answers to the following questions.  

    
    Assuming that your kernel code uses 13 32-bit registers per thread when compiled, 
    how many threads can be simultaneously executing on a GeForce8800 GTX GPU, 
    which contains 16 Streaming Multiprocessors.  


Grading:  

Your submission will be graded on the following parameters.  

Demo/knowledge: 25%
    - Produces correct result output files for provided inputs

Functionality:  40%
    - Runs correctly when executed on a G80 device.
    - Shared memory is used in the kernel to
        amplify global memory bandwidth  

Report: 35%
    - Answer to provided question.
