i get like 3-4 WUs done in 24hrz but some times i give my cpu a little rest for an hour and start again! ;)
(i have it on 24hrz)

that's actaully bad for your CPU, if you let it cool down regularly after being at a constant heat then it damages the chip more than keeping it going at full tilt.

The reason is because the CPU expands and contracts as it heats up and cools respectively - if this happens too much the CPU is in danger of cracking. There is no reason not to run your CPU at full usage 100% of the time, it might actually extend its life.
 
You've only got one processor, but some parts of it are duplicated. These are the simpler components which don't produce much heat, such as the main instruction path, the arithmetic unit etc.

It has to report that it has 2 processors so that windows can schedule it to execute 2 tasks simultaneously. That effectively means that with two tasks which for the most part only use the duplicated parts you can get more performance out of the chip.

Unfortunately F@H mainly uses parts which aren't duplicated - the MME stuff and the FPU. These are complex units and produce large amounts of heat, which is why they aren't duplicated. So although you could have 2 copies of the program scheduled to run, in practice they would be waiting for the shared resources to be free.

There's even a down side to HT when you want to run another program, even with only one copy running. Windows sees that it has a spare "processor" which can run your prog, it doesn't know about the shared resources. So windows schedules your prog and doesn't bother interrupting the other FPU/MME intensive prog. If your prog uses the duplicated parts there's no problem, but if it uses the shared parts then it runs like a dog.

Nice one Intel - how to slow down our systems by not thinking out the problem. Nothing new there then. :dry:
 
Here are two signatures I made...

stopped using it srry, it was causing to much 'errors' and 'lags' on my custom GUI. even on the lowest CPU

Seti is better in my eyes, nothing against it - both are useful...

I used long time Seti@home, but finally prefer Kazaa running ;) But, no Seti is nice...

Just got me this morning a "Protein: p858_p53dimer858"
It's 160 points worth, and takes 25 minutes to complete a frame
----------> almost 42 hours to complete this WU
----------> 160/42 = 3.84 points per hour!

I want more of these ! :rolleyes:

I've got that one on my main pc, and P859 on my XP1700. That one is going to take about 56 hours, so there won't be any changes to my stats for a couple of days. :(

On the up side, a friend is going to GIVE me a dual Athlon mobo and processors (1 Ghz I think), then I will really be able to raise some dust.

Btw, anyone got any info on ocing dual processor systems? :lol:
 
LOL, thanks again. I guess I will leave well enough alone.

I believe I will have my other comp up and running again within the hour so I will just run it as well.

Thanks.

if anyone has probslems using the -forceSSE command with amd processors, there is a beta gromacs core which fixes the problem. it will be automatically distributed soon if you dont want to use a beta core.

http://www.stanford.edu/group/pandegroup/folding/beta-core/

to install, download the new core. close folding@home, and put the new core in the f@h folder, then run f@h again and it will use the new core for gromacs WU's

Thanks for that, I'll try it when I've reinstalled XP (AGAIN, damn NIS crap).

And I'll try it on linux tonight. :lol:

Edit: it's a total lemon, locked up my linux system almost immediately.
