Who says PTrpCage is only good on P4s?

[Fever]

I'm getting 8:22 per frame. Sounds decent for 6.2 points. :D

(I get about 7 minutes on a P182, which is worth 5.6)

[OSUmaxx]

I get 8:20 on the ptrpcage, and around 7:20 on the p182 @ the same speed as you. Do the math, and I think you'll see that its better to do the p182s.

[Gnerma]

I just did the math on those two proteins based on OSUmaxx's times, here is what I got.

P182 @ 7min 20sec a frame = 10.9731 Points Per Day
PTrpCage @ 8min 20sec a frame = 10.7136 Points Per Day

As you can see the P182 using the Tinker core is slightly faster. Nobody said that PTrpCage WU's are only good on P4s. The XP still owns the PTrpCages. PTrpCage WUs offer a very large increase in production on P4s, so much so it's worth taking special measures to ensure P4s get them on every WU. :beer:

[OSUmaxx]

One benefit to using the advmethods switch on an XP is so you don't get all of the little 0.7 pointers that slow up production. If you're seeing a lot of those (like I have been lately), you might want to turn on the switch.

[Fever]

Yeah, I've been getting a lot of .6 and .7s. :( There's no switch to get a lot of P182s, is there?

[Gnerma]

Just for a comparison I figured the numbers on my P4.

1.8 Northwood P4 @ 123 FSB x 18 = 2214 MHz
PC800 Rambus @123 x 4 = 492 x 2 = PC984 RDRAM

P182 @ 12min 50sec = 6.2830 Points Per Day
PTrpCage @ 8min 40sec = 10.3013 Points Per Day

No there is no switch to run just P180/P182's. As soon as Stanford is confident of the stability of the Gromacs core & they get the WUs sent out to everyone they've talked about having the assignment servers discern between CPU's and use that information to decide what WU to send them. Of course you could go straight to the official forum and talk to the guys who run the project..

For Tualatin (Celeron) @ 1.47Ghz, both PTrpCage and P182 take around 12mins with my 2 years old motherboard :p

Looks like they've improved P4-performance even with normal WUs... so it's getting even with P3. I remember P4 was former much slower than P3, but now it looks P4 is faster in Gromac-WUs than P3.

Man its gotta be the memory. I read the other thread from gnerma about those gromacs wu's. My non-overclocked XP2000 with PC2100 takes about 23mins a frame for that protein. Ouch. Definitely have to keep this mind for the next full blown rig.

[Gnerma]

belorsch, that sounds wrong. Read the part about the client turning off your assembly optimizations and see if they've been turned off. That's probably your problem.

Well, I did read that gromacs love memory bandwidth, but I think that's not your problem. I'm gussing that your SSE is turned off. Use the -forceasm command to see if it improves your times.

[belorsch]

OK guys I'm testing my pc just to bo on the safe side. Prime95 ran all night without problems and I will let it run till this afternoon. That system isn't oc'd because it needs better cooling but I have questions about the memory. Hopefully it will be resolved soon as this is my #1 system.

[Arkaine23]

Its not your system, except that maybe its overclocked just a little too much for Gromacs to be stable. So the folding client may have disabled SSE for its own use and nothing else. There's a way to turn SSE back on in the client as mentioned above.

[Gnerma]

belorsch, remember too that if your system is just unstable, weather it has to do with the folding or not the client may turn off your assembly optimizations. Like if you crash your box by doing other things and your folding client gets shut down improperly a few times.

Also, if you haven't already, check this link for some good help on Gromacs stability.

Ah yes, I get BSD's on a regular basis when playing NWN. I need to rebuild this pc but right now is a bad time. I should have thought of this. Thanks guys.

[Arkaine23]

I had trouble with NWN too. New Ati drivers helped.

[belorsch]

I tried this. I went to the boards website and dol'd latest driver. I forget the name of the company but its Xtasy GF2 GTS. I want to upgrade to an 8500 but I have been pressed for time lately. Man getting a home ready for sale is a pain.
