matrix_multiplication

Overview

Helper files to show the benefits of threading when performing matrix multiplication.

How to run

run make to execute the makefile. This will compile the binaries listed below

Helper functions

make-matrix

• generates an mxn matrix and populates it with rand numbers
• execute with ./make-matrix -m ## -n ## -l ## -u ## -o outputFile with the following flags -m: rows -n: columns -l: lower bound for rand number generator -u: upper bound -o outputfile (typically in the form of #.dat)

print-matrix

• prints a matrix created with make-matrix
• execute with print-matrix -i infile.dat

pth_mat_vect_rand_split.c

• multiplies two matrices together and outputs the resultant matrix and time stats. This is done in the form of Ax=y
• execute with ./pth_mat_vect_rand_split -t <thread_count> -A <A.dat> -x <x.dat> -y <y.dat> -t: number of threads to process with -A: input matrix -x: input matrix -y: output matrix
