double gromacs

[coolpup32]

I cant seem to find much info on double gromacs. Is there another switch that you have to add or does the computer automatically pull a double gromacs WU? Just a lil confused. Thanks

its like a 100pts

Hey are you guys using the -advmethods -forcesse Flags on your clients?

The -advmethods automatically downloads the latest and greatest cores from Stanford.

actually wer're using -advmethods -forceasm

I have a 936 double on one of my machines now. Happy folding everyone.

you know those double gromacs seem kinda slower

Any word on how to get a double?

really its luck of the draw.... you can look at the server list and look for adv in the options... you can re download wus if you want untill you get one... but

Does it have any thing to do with SSE2 code in processors?

from what i know its a new core that uses more accurate calculations (ie uses doubles instead of floats) .... hence the name double gromacs and yes SSE2 procs will be better at it:

Pentium 4
Xeon
Athlon 64
Athlon 64 FX

Actually, for the point value I think that they are faster on my rig and don't heat the CPU near as much as regular Gromacs which I really like on a HOT day like today!

Too bad I don't have one right now.

hum maybe something wierd was going on with me then... ie some prog stealing cpu time ... i'll check again if i get another

G'day folks. I may not be all that welcome since I fold for OCAU, but here's my 2 cents direct from the horse's mouth (Bollocks @ OCAU, the folding guru.)

On an athlon xp, both gromacs and double gromacs will lower your folding points production, by 10-50%.

-advanced methods tries to get Gromacs before Tinkers. Do not use on an athlon xp system, but definitely use on a p4 or athlon 64 system.

On the otherhand P4's love Gromacs, they adore Double Gromacs.

If I could get Doubles all the time, I would be able to produce 3000 points + per week. Tinkers suck on a P4.

For folding athlon 64's are the most versatile, but like P4's somewhat better at Gromacs and Doubles.

Recommended settings for 64's are both advanced methods and forcesse.

P4' s - adv methods only

xp's -forceasm only.

Hope this helps.

Advance the cause!
