The Windows SMP core has has so many problems that I think F@H has backburnered the updates until they get help from M$. The GPU is really smokin’ now, tho.

Clean off everything from the old F@H directories. Use F@H to uninstall them to get rid of old registry commands, or use a registry cleaner.

Make four folders, F@H 1, F@H 2, F@H 3 and F@H GPU. Download the latest Windows clients 6.23 from here:

http://folding.stanford.edu/English/Download

And get the console version. Copy the program into the 3 F@H directories. Go into each directory and run the program within.

You must:

1. Include your same user name and team number (36120)
2. Choose Advanced Options = Y
3. Sat Yes to “Launch automatically, install as a service in this directory (yes/no) [no]?” Y
4. Under Advanced Options, you can set the Checkpoint Interval and the -advanced options (I say yes).
5. Most important, set each Machine ID to a unique number. I always set folder 1 to Machine ID 1, Folder 2 to Machine ID 2 and F@H 3 to Machine ID 3.

If you want to keep one system tray GUI running that is OK but I don't when I am running the GPU client.

Now, you will have three DOS boxes all merrily crunching along. I let them download a work unit and start crunching away. To close these DOS boxes, click inside the DOS box with the mouse, hit Ctrl-C to close the program properly, once for each box.

Reboot the computer and you will have three F@H cores running when you login. That leaves one core free for the GPU.

About the GPU - which video card do you use?

Which vid card were you running? Few hundred ppd sounds like some ain’t right. I installed a EVGA GT9400 on my kids’ computer and can expect 800ppd from it. I rally like this card since it can run on pretty low wattage (300-350).....C

I bought an ASUS EAH4350 Silent video card, but I was disappointed, the video on the motherboard worked almost as well for Folding or video. Running the GPU version also caused video problems. I was thinking I might dedicate one of the GPU’s to folding and the other to video, but I didn’t have much luck setting that up and when I saw the GPU version wasn’t getting very many points, I quit trying.

As I mentioned the GPU was getting maybe 300 points per day, where the SMP was getting about 1000 per day with 4 cores. Trying anything other than the SMP version didn’t seem worthwhile.

Is there an advantage to having separate folders for each of the SMP cores? You can tell the setup program how many cores to use, and it will run separate instances of Folding on each of the cores, all from a single directory. That is how I have it running now.

OK, I see now, you are proposing to use the standard cores, not the SMP version, hence the separate folders. That should be easy enough, I do wonder about point production, though. I’ll have to experiment a bit more on the GPU situation, I suppose.

Is the ASUS you current card?

If you have SMP working then let it fold with all 4 cores. I have never had a good install with the SMP core.

My thought was to run consoles and then dedicate a core to the GPU.

If you still have the ASUS card then you should be good for over 1,000 ppd. The card has 80 streaming processors, not terrific, but more than fast enough to run F@H GPU.

:’) Yeah, the good old days. I think he actually uses the game port to network ‘em, so it’s binary.

I have an ASUS EAH4350 Silent video card that I was hoping to use. I took it out of the machine and was Folding on the ATI Radeon HD3200 on the motherboard until I gave up on GPU Folding.

The ASUS is ATI based, but apparently not 100% compatible with the built-in video.

The system is running pretty warm right now, another reason I am using the motherboard video (but I don’t actually know how either video affects the heat situation). The fan keeps the temperature around 50°C, but if gets a bit noisy for my taste sometimes.

Like I should scoff, having started out before S-100, using 16 switches or cassette tape.

When she wants to hit below the belt, my wife still reminds me when I drug her out in a blizzard (for Texas) to a clearance sale at Best Buy to get a single sided, single density (90K) floppy for $200.

I quit using it before summer hit. Ouch.

No, the ASUS is resting in its box.

I never got the SMP version to run as a service. I just run the console version in a cmd box. It might be worthwhile to switch to the standard version so they can run as services. If I have a power outage (happens fairly often here) I have to log in before it will start folding.

I will give the GPU version another shot, if it will do 1000ppd that would be sweet.

...Cray XT Jaguar . . . boasting a massive array of 45,000 AMD Opteron processors...

Is that a typo?

Forty-five thousand?

The restart issue is the main reason that O install console F@H. Not as fast, but I never miss a deadline.

The 4350 is not a great folder but it has a very sweet spot based on its low cost.

As long as ASUS didn't do something strange to the drivers you should be fine.

I am using the ATI driver 185 instead of the manufacturer's drivers here.

Well, about 181,000 cores, so about 45,250 actual four-core Opteron chips.

I wonder if they’ll take advantage of the OpenCL support in OS X Snow Leopard to squeeze more out of Macs. Sadly, my iMac just misses the cut for OpenCL support.

But the equations going through the supercomputers still need to be correct: and THAT is where the all the power and speed in the world running false AGW assumptions

One of the earlier computer acronyms was GIGO: Garbage In, Garbage Out. It's in an old 60s computer dictionary I have.

"It's been a while since we have had a Folding@home thread, and figured that a discussion of supercomputers is a good place to restart."


And you picked a nice article to do so with, too! (Except, perhaps, for its little global warming plug... All those Man Caused Global Warming proponents aren't putting nearly the amount of computing power (or smarts) into their "science" that we're devoting to protein folding with Folding@Home. They need a decent distributed computing project and a goal that isn't driven by redistribution politics, before they can claim any knowledge.)
Thanks for the ping!

It's not a supercomputer, but I've bought all the parts for my new PC... an Intel i7 920 processor that I hope to overclock with a Cooler Master Hyper N520 CPU cooler on an EVGA X58 3X SLI motherboard. I have a pair of GTX285 1GB video boards (with room for a third...), 12 Gigs of 1600Mhz triple channel DDR3 Ram, a pair of WD Caviar Black 1 TB hard drives, a BluRay Rom, and a BluRay/DVD/CD burner. It's all going into an Antec P193 case with a Corsair 1000W power supply, and it will drive a 30" Dell 3008WFP Widescreen and two vertical 24" monitors, one on either side.

I'm still not decided on the OS, but I picked up Vista Ultimate 64 to play with first. I'm in the middle of moving, so don't expect my folding points to madly accelerate just yet... ;-)
