I set up my laptop to fold while I'm at work. Stupid dual core is slow! :mad:

Going to ask my boss if he'll let us fold on our lab computers :)

Although, they are only measly P4's >.>

...but they are on all the time :D
 
No way it's worth it on a p4 any more. A p4 e 640 @ 3.8 GHz will make about 160 ppd running 24/7 on uniprocessor WUs and use a lot of power doing it. P4Cs make about 39 ppd/GHz, the Prescots (P4Es) make about 42 ppd/GHz. THere are a few bonus WUs out that will double that production.
 
With an expontntial bonus for quick return on the SMP WUs, you will drop your ppd dramatically by running multiple clients on the same machine (until you go past 24 core machines). Running two SMP clients on one machine, each WU runs at 1/2 speed and the bonus you lose means you'll make about 2/3 the ppd.

Example:
i7 @ 3.8 GHz
single instance p6050
TPF: 3:00
ppd: 17,955

i7 @ 3.8 GHz
two instances p6050
TPF: 6:00
ppd: 6348 x 2 = 12,696

You suffer a 30% loss in ppd running two instances. Stanford really wants each WU back as fast as possible and rewards you for doing so.
