Summary: From 1987 to the present, I have been a member of the systems staff at the Caltech computer graphics lab. This lab had a very heterogeneous cluster, and a number of unusual configurations, so I have a lot of experience with cross-platform interactions and making customized tools to handle unusual systems requirements.
