A lot has been written about how to design, execute, and report the results of computational experiments. This has obvious connections with open source software and the broader "open science" movement. Another important issue is the difference between "my code is faster than yours" research and research that helps us to better understand the properties of algorithms.
Some references on computational experiments and testing that you might want to look at include:
