  1. Amazon's Elastic Compute Cloud (EC2) can be accessed via a number of differet instance types. For the purposes of our comparative genomics problem, we elected to utilize the extra-large high-CPU instance. Note that the total cost for a small instance is equal to the total of the extra large, despite the large difference in computing time.
