I work on a PII233 with 322mb of RAM. RAS is a smaller, easier protien, so it finishes slightly quicker. I'm on a Win95 also, so I can't get a 40 or 50 hour unit working without a reboot. All my SOD protiens go more than 60 hours and can camp down on a particular molecule for over 20 hours sometimes.
Yes it is about fighting cancer, but UD sends out hundreds of copies of the same W/U, so me CTRL+ALT+DELing will not ruin the final results of the project. And yes, I also did join with UD for the possibility of winning one of the prizes. I need the money.
If you have a faster computer that can do several W/Us a day, then do not 'throw out' units. I encourage all to keep them if you can. I can't. If I keep one, it will crash and might not make one % before it does again.
