GPU WUs say WAIT

Hi y’all,

I started folding in February on a fairly fast PC that is also doing GPU WUs. I played with the folding Speed setting, and found that I could let folding run at Full Speed, w/o any overheating, so I’ve been doing it that way, 24/7. I am running fah-installer_7.3.2_x86 on Windows 7 64-bit with 4GB RAM.

It’s a Dual Core CPU, and I am able to do one (1) CPU WU, and one (1) GPU WU at a time. Multi-Day Jobs are being done in 3 and 4 hours. I was impressed. Didn’t think the PC was really that fast.

At first, it ran undisturbed, 24/7. I started having Performance problems with my main PC that I use for Everything. That PC is older and much slower, so I started using the folding PC at night to play and chat in a Lounge on ECF, about a week ago. Everything had been going well. folding would let me stop it, I could play for a while, and then turn it back On.

I have been folding WUs 10501, 10502, 10503, and 10504 ever since I started folding. They are GPU WUs, and they keep running, somewhat in succession.

Last night, when I turned folding back On, WU 10503 said Wait 3 hours and 8 minutes. I worked on the other PC for a while, came back to check on folding, and it said Wait again. The Wait period will time out, but another Wait period will start, and the WU never starts running. A CPU WU is running OK.

So I have two questions . . .

What is causing WU 10503 to keep saying Wait, over and over? . . . and How can I get it running again?

How can I get 3 WUs running? . . . 2 CPU and one GPU?

Thank you!!!

There were some network problems at Stanford that effected the F@H servers starting yesterday. Most servers are back, including the two with work for your older nVidia GPU. The client should eventually download a new WU to process, but the connection load is just starting to come down after clients all started checking in for uploads and downloads. If it doesn't clear up in few hours for you, please post your log and we can take a look at it to see if there is another issue.

As for getting 2 CPU WU's running, if you mean on the PC that already has a CPU and GPU folding slot, that is not recommended usually. You can install the folding client on the second PC, just use the same username, team and passkey.

Thanks Joe,

I'll leave well enough alone for the CPU WUs on this PC, and just wait a little longer for Stanford.

Much appreciated!!!

You may also want to upgrade to the latest release version (v7.3.6). Simply setting the Folding Power Slider to Idle would probably be ideal for you. If you want to fold with both CPU cores, go to Advanced Control -> Configure -> Slots -> cpu and set CPUs to 2. That will get you CPU:2 Work Units which will use both of your CPU cores.

However, make sure that your setup is fast enough to complete CPU:2 WUs within Timeout - formerly known as Preferred Deadline. If daily use and/or GPU folding takes too much of your CPU time to consistently achieve that, please revert to CPU:1.

The idea of the power slider is to try to pick options that work for everyone. If FAH takes too many resources on a slow machine, it SHOULD be set so that it only folds sort of like a screensaver only comes on when nothing else is happening. That should take care of the only-fold-at-night option and maybe pick up an extra hour or two during the day while you're not at the computer.

For most computers, the OS scheduler does a good job of running FAH at a lower CPU priority than anything else on the computer so that part of FAH can probably run continuously without impacting the performance of whatever else you're using the computer for. If FAH is using the GPU, the chances of an unacceptable performance degradation is much higher so most of the slider settings suspend GPU processing when the computer is not idle.

The only way to find the best setting for your computer is to adjust the slider to whatever performance level let's you use your computer for whatever you choose to and let FAH have the rest of the unused resources.
