Looks like my second WU is going to miss the deadline. :( Got hit with a huge WU this time and I just don't have the power to get it done. Hopefully my next WU will be a bit more reasonable and more in line with my crappy PC from several years back

That's surprising. Is the Wu "folding" on a PC that is being turned off or going to sleep?!

No. My PC is up and running 24/7. When I got the WU it had a lead time of 12 days. I have been running it nonstop since I got it and I still have 2 days left to finish it. However, the deadline is tomorrow. I have cut back my CPU usage to 80% in the F@H control panel because anything higher kills my PC performance and runs the cores too close to max temp. Like I said, my PC could really use an upgrade.

I did not cut it back but someone (read that as my wife) did. It was cut back to 10% so I just fixed it.

On another note, what is the difference between the timeout and expiration dates?


My understanding is that the "timeout" value is in place in the event that your PC is not folding at all, it will probably reassign that WU to somebody else. The "expiration" will kill the job, and reassign you another WU.

Did you cut the CPU usage back after you got the WU assigned? I'm curious because it's supposed to calculate times/processing power when assigning the deadlines, I think..

Deadlines are calculated by the F@H systems and has no bearing on what your system was when it was assigned. They use a dedicated machine, and type of machine, to benchmark them and if by chance you get a WU that they benchmark'ed better than what your system can perform and you cut back or pause the CPU at anytime it's just that close sometimes. It's not supposed to assign you a WU your architecture can't complete running full out but sometimes their benchmarks are so close that if you do happen to pause, even for a few hours or scale back cpu usage max, you miss them. Sometimes they are just wrong on their estimations and you'll see a new core going through various changes in the deadline times as they get it more scaled to the max % of users who could get the core.

Of course things may have changed totally over the course of the last few years I was not folding but seems likely based on what I've seen on my own WU and deadlines.

yea your pretty close, its still the same. but i have noticed if you change the power its using it will try to recalculate what your hardware is capable of and then adjust the units its sending to fit better, if your constantly playing with the slider or suddenly turning off the pc for two days at a time after its been on a week it will mess with the units you are currently working on.

I must say this new version is a definite improvement over older versions, cant wait to get a real pc after the new year and get off this weak laptop.

Cool.. yeah I've seen mine fluctuate a few time on results and deadlines on this client but it seems pretty good.

In the past if you didn't mean the deadline you got nothing and I believe now you do get some partial credit. I'm just shocked at the raw power of the cuda engine these days as I've got nearly 1/2 of my entire points over the course of several years fold. Some thousands of WU's to get to 1 million points and I'm nearly there now under 100 WU's :shock:

Installed and running and boy is it a resource hog.
yup but you can adjust the amount of resources it is using so you can have room to use the pc for other things. only on default settings will it try to use everything.


About the cuda. I know guys on hardocp who have multi card rigs just for folding. it is well known the architecture of the nvidia cores are more dense then even the new intel chips, something like almost 2X the transistor count now.

And when you think about it the video card has more crunching to do with respect to games anyways, where a cpu just executes the code of the OS the GPU has to calculate millions of triangles, dimensional perspective, shading, coloring, angles, effects like fire, smoke and hair. millions of colors, and textures like bumps and water ripples, and its doing it at 50 frames per second.
that is some serious math going on, so using it for something like folding is almost a no brainer.

I have a question. We will be going away for a few days next weekend. We don't like anything running and hubby turns all machines off, even the wireless. I don't want a work order sitting in limbo for four days. How do I tell the program to stop sending them for a while? When I get back, how to resume getting them?

Ok that's two questions. ;)
