This week was quite hectic for me with course assignments and their merciless deadlines. One such assignment in Advanced Computer Architecture was simulation of various benchmarks in alpha architecture in simplescalar , a well-known computer architecture simulator. I was supposed to run a total of 4 benchmarks with different configurations of cache memory, instruction issue widths, commit widths, in-order execution modes, etc and I had to plot the required performance parameters for every benchmark. A conservative estimate would be around 40 plots! Since the simulation platform was Linux, I could breathe a sigh of relief since most things can be automated using a powerful tool called shell. Scripting made my life easier here since I can automate a bunch of simulations without having to keep an eye on each and every simulation which would take anywhere from 20 minutes to 20 hours. The problem arose when it came to plotting the performance results. Because, each simulation
