	Does the current application checkpoint? If so, how frequently? Any issues if I reboot the PS3 when a result has not yet completed crunching? ____________ Reno, NV Team: SETI.USA

	I\'ve had no problems, I during testing have interrupted many tasks, some of them multiple times, no ill effects. The only test I did not try yet was actually pulling the plug out of the unit, to simulate a power failure (since my is on my UPS). I was planning on trying this, but I need to catch a task when its not very far along, just in case it trashes it. I don\'t mind wasting say an hour of work, but I would hate to kill 21 hours. Note to GDF: Your applications have been the best of any project yet to test, with the least number of problems. You do a good job at this. :)
