Default SMP Gromacs WUs supposed to take so long?

First time I've run into something like this.
Can someone explain what's going on?
Should the SMP Gromacs Core WUs take that much longer than CVS?
What is the difference?





[19:16:35] Folding@Home Gromacs SMP Core

I haven't noticed any of the other WUs "writing local files" between each step.

That project uses the older, A1 core and not the faster and more efficient A2 core.

Your PPD doesn't seem to be right for the A2 core WUs.

I'm folding 3 VMware clients at 3.486GHz right now...
I usually get around 2500ppd per client.
If I run 4 clients I get around 2200ppd per client.
So long as they are the A2 WUs, that is.

I'm curious, Arinoth, why you're running stock speed?
These things are pretty easy to overclock.

Do you have hyperthreading enabled? I think I've seen more PPD from a Core i7 running the Notfred client.

If you fold 24/7, you can try running the 25k point WU. If you complete them in under 4 days, you get a bonus. However, the frame time for each percent is like 40+ minutes in order to be eligible for the bonus.
