#ECE420Lab1 Code for ECE 420 Lab 1

The purpose of the lab is to create a variable thread (determined via command line arguments) parrallel matrix multiplier. It takes a .txt file as input generated by matrixgen in data_input.txt, and outputs the resultant matrix to data_output.txt. The only student written code is in main.c (the actual parallel algorithm and thread handline) and Makefile (compilation via shell gcc commands).

##Simple Run Instructions:

• Run "make" to compile, or "make run" to compile and run the check

##Make Command List:

• type make followed by one of the commands to execute it

###compile (default command):

• runs clean, main, matrixgen, and serialchecker
• can be called by just running "make"

###clean:

• removes tmp/, main.exe, main.o, matrixgen.exe, matrixgen.o, serialtester.exe, serialtester.o, data_input.txt, data_output.txt,

###fix:

• changes the permissions for check.sh to include u+x

###main:

• compiles main.c and lab1_IO.c main.o or main.exe (cygwin)

###serialchecker:

• compiles serialchecker and lab1_IO.c serialchecker.o or serialchecker.exe (cygwin)

###matrixgen:

• compiles matrixgen.c with output matrixgen.o or matrixgen.exe (cygwin)

###check:

• runs "./check.sh"

###run:

• runs compile, fix, and check
