Is it running Microsoft Vista Ultimate? THAT'S a killer project.

Nobody knows what new projects will require, but they have been all over the place. The requirements can't be too high, or the scientists might as will run them themselves without the grid computers.

(You can't mix BOINC and UD at the same time.)
If one of these doesn't quite do it, it is always possible to run a compatible non-BOINC and non-UD version project like DIMES to give your computer something else to do. It does not interfere with either BOINC or UD. DIMES only does something when connected to the internet though, since it does a lot of pinging... I'm guessing that it takes something like 5%-10% of computer power at intermittent moments. It will slow WCG down by about that much. If not connected, it just sits there in inactive mode.

I am connected to 39 BOINC projects myself, and I really don't know of any others with any higher requirements than these at WCG.

The largest variable I've found is time. Some project workunits can run in as little as 2 seconds. The climate simulation workunits can run for many months each, but they assign interim points something like daily.

HPF2 is fairly intense. There will be a few more projects start up this year, we think. Tune in now and then to recheck the mix.
