||After discussing this with the stakeholders of the contest we are considering switching to a more powerful architecture, unless contestants object to this move, claiming that they have already invested too much effort in optimizing to the original setup. So if you have an opinion in this question, please let us know by answering this post whether you are for or against changing to stronger test machines.
One more question, in case you agree to the change, what architectures you prefer and why? The options we are considering are g3.8xlarge, g3.16xlarge and p2.8xlarge. Of course price is an important factor in the decision, but you can also weigh in with your opinions.
