F@H unit, 2500000 takes 15 hours to go 10%

[Markfw]

Ath this rate it will take 150 hours to finish, or 6 days ? I have never seen this big a unit. Anybody else, or is possilbly something wrong with this box ? CPU-Z says it really is running at 2078, 189x11. 512 meg memory, 80 gig HD.

What's the info in the unitinfo.txt file? I've been getting monsters that are allowed a month and a half or more to finish lately.

Do you use the -forceasm flag?

If not, and you restarted after a crash or improper shutdown, the client will not use optimized code. It will take MUCH longer to finish.

You can get it to use optimized code by correctly closing FAH and then restarting FAH.

You will see a line like this:

[22:05:56] Assembly optimizations on if available.

when the client starts folding if optimized code is being used.

Due time: February 9 10:29:17
Progress: 30% [|||_______]


Project: 1405 (Run 65, Clone 15, Gen 0)

Entering M.D.
(Starting from checkpoint)
Protein: p1405_polyQ44 in water

Edit: And yes I restated: I just fixed the shortcut though. It didn;t have the standard flags:-advmethods -forceSSE -forceasm

Yep, those "in water" units are absolutely huge. They take almost a day and a half on my 3.6GHz P4 running two instances of F@H. There's a reason you get two months to finish those suckers 🙂.

 

[Markfw]

So how much difference do those flags make ?

 

[MDE]

Not having SSE enabled can cause a huge hit in production.

 

[Markfw]

Can you quantify that ? Like from 18 hours down to 12 ?

It's possible, but I can't give any hard numbers.

 

[Markfw]

Well, my first tick was 30 minutes instead of 1hr 30 minues. Incredible !!!!!! That would be 50 hr, instead of 150 hr.

on an off topic anyone know how to check the flags on a service install since they arn't in the normal parameters sections in services ?

in "regedit"
I believe I can find the instructions

from here

1) Shut down that instance through the Services manager snap-in
2) Run regedit and go to key HKLM\SYSTEM\CurrentControlSet\Services\ and edit the entry ImagePath, adding whatever flags you wish to the end. Exit regedit.
3) Re-open the Services manager snap-in, and verify that your changes appear there, and then restart the service.

The usual "mess with your registry and mess up, it's your fault" disclaimer applies.

^ Thanks

Wolf, I was thinking about where I saw that last. I should remember my own work a little better (I wrote the guide that blub came from but IIRC it was ProviaFan or GLeeM that found the link to changing the flags for a service install).

I think in one thread both of us found the link and posted at the same time... or something like that. 😉

I'm pretty sure the -ForceSSE flag no longer has a function. (The -forceasm flag turns on SSE/3DNow if available.)
