My name is John O'Donnell and live in Lake Oswego, Oregon. I work for the Bonneville Power Administration in the Information Technology field. I enjoy both the science and sense of community with BOINC distributed computing. I enjoy finding Titan's using PrimeGrid, especially with PPS. Although I do not game, I use my 3.2 billion transistors on my EVGA GTX 470 to help my team SETI.USA stay competitive in the PPS Sieve, and the BOINC statistics. My primary computer, which runs Windows 7 Pro, and is completing a PPS sieve every 7 min 38 sec @ 2,311.00 credit per unit with the most recent Proth Prime Search (Sieve) v1.37 (cuda23). Here are my primary computer's specifications - Intel(R) Core(TM) i7 CPU K 875 at 2.93GHz [Family 6 Model 30 Stepping 5], Memory 4094.05 MB, Coprocessors NVIDIA GeForce GTX 470 (1248MB) driver: 26099. Operating System Microsoft Windows 7 x64 Edition, (06.01.7600.00), BOINC version 6.10.58.
