F@H 160pt Gromac - Taking Forever

Anyone else crunching one of these p858_p53dimer858 units. This thing is taking its time. On my P4 2.4 HT the WU time is estimated at around 65 hours, with each frame at about 38mins!

Good points though.
 
i'm getting bout 35-42 mins on my 1700+(thats only when i close all other apps and leave it alone) 🙂
 
grimlock2003, are you running two instances of F@H?

If you aren't, make sure you have SSE enabled. It should be somewhat faster than the times you have listed, although I don't have a specific benchmark for a 2.4 P4.
 
Yeah, I have a GUI and CLI version. The 160pt gromac is running in the GUI version 🙁. I have the following enabled on both instances: -forceasm -advmethods.

Is there something I need to do to speed this up? On other forums I've seen the times for this unit more in the mid-20 range. Those were AMD's though. After I'm done with this WU in the GUI I'm going to move to two instances of the CLI version. That should help a bit I think.
 
If you're running two instances, you're times are about right. The 160 point units are pretty generous compared to some of the other units. It just seems like they aren't because they take so long.

The hyperthreading advantage is somewhat less with F@H than SETI.
 
My P4 2.2Ghz 533Mhz FSB folders with no HT average about 25-26 minutes per frame. My PIII 1Ghz machine averages about 1 hour 6 minutes a frame for the same unit.
 
I'm not too happy. :disgust:

The 160pt WU finally finished today about 4pm. My machine accidentally rebooted at about 7pm. After it booted back up the WU started again, from the beginning. The machine has been off and on several times when it was working, but always picked back up from the last checkpoint.

I would figure that if it finished 3 hours before the reboot, I wouldn't lose about 3 days worth or work!
 
Unfortunately, you may have a case of the two clients interfering with each other. When running two instances, I think they both need to be started with the -local argument (set it in the Shortcut Properties). I've never heard of using a GUI and CLI at the same time. Two CLIs in separate folders seems to be the norm for SMP or SMT setups, and causes a lot less grief than trying to run a GUI and CLI.
 
It may be that it was finished and the client downloaded another wu of the same kind. Find the FAHlog.txt file and look at it.
Hopefully you see something like this near the end of it:

I think this is your stats page, does it seem that 160 points was added today?? I sure hope so.......
 
No, my log file doesn't have the "Results succesfully sent." I checked thinking that I had downloaded another of the same WU, but no luck. As far as points I would have about 370 after the 160 addition.

Oh well, no biggie.

SSE is an instruction set Intel developed to help speed up certain calculations.

Enable it in Folding@Home or enable it through hardware?
Through hardware you need a Pentium 3 or higher (or Celeron derivative) or an Athlon XP (or Duron 1.4 or higher).

Through software, you need to add the -forceasm (for Intel) or -forceSSE (for AMD) flag to the shortcut for F@H.
