TIC4005 project 2 – MPI, Measurement

This code was originally from https://github.com/fabien-dournac/parallel-heat3d-c, but I have made some small modifications. Note the following…

1. The directory includes a Makefile, and the command make will compile the program, with score profiling.

2. The directory includes a run script ./run_performance_heat3d which will automatically run and record various tests on different sized 3D worlds. Cumulative results are put in the file performance.txt.

You may want to modify this and the machinefile to explore more deeply.

3. The directory includes a MATLAB script ./plot_performance_heat3d.m which will automatically graph (some) results from performance.txt. You will have to do this on your own machine using MATLAB. You can of course also use gnuplot, or excel, or grapher, or…

Take some time to look at the source code of the program, and observe how it is supposed to work.

Step1: Compile and run the program (initially) with the unchanged script.

Step2: (Later) modify the script to record as well any other readings you wish to make.

From these recordings, you should be able to graph what is happening for your sets of runs.
