TPF Calculation Error

Post by MightyMayfield »

This machine has been running for almost 2 years at this point and this is the first time this has happened. Honestly did a spit-take when I saw the 477M PPD number :lol:

System is a 3990X with three 2080ti's. Any tips on how to avoid this from happening in the future?

This can happen shortly after resuming a WU, especially if its last checkpoint was close to a full percent. It takes a very short time to complete, and the TPF calculation is over less than a full frame. About the only thing you can do is ignore any TPF or PPD estimates shown after running for a short time.

I recently had an error that caused a temporary points glitch. It was a clock skew error, and increased my estimated points by around 33% while that frame was processing. I was folding only on a single GPU at the time, and as of the next frame the estimated points were back in line.

This was the first time I've ever encountered this error code, and I really have no idea what caused it. The system remained stable and kept folding just fine when it took place. It might be worth looking at your logs to see if you get a similar code.

Code: Select all

23:04:41:WU00:FS01:0x22:Completed 12500 out of 1250000 steps (1%)
23:29:17:WU00:FS01:0x22:Completed 25000 out of 1250000 steps (2%)
23:29:19:WU00:FS01:0x22:Checkpoint completed at step 25000
23:51:36:WARNING:WU00:FS01:Detected clock skew (4 mins 04 secs), I/O delay, laptop hibernation or other slowdown noted, adjusting time estimates
23:51:36:ERROR:Receive error: 10053: An established connection was aborted by the software in your host machine.
23:53:36:WU00:FS01:0x22:Completed 37500 out of 1250000 steps (3%)
00:18:08:WU00:FS01:0x22:Completed 50000 out of 1250000 steps (4%)

But then again it's also very possible that with three top producing cards you are breaking a server or something. The easiest way to fix this would be to send me one of the cards. :lol:

Your accurate estimate is about a year's worth of folding on my little integrated graphics Ryzen system. It's great to see users like yourself and dedicate so much in resources.


Edited to add the error code info.
Fold them if you get them!

FYI, your cpu is overextended and will result in lower PPD overall. You have a 64 core processor running 3 GPUs which will use at least 3 cores but even if they don't use all 3 cores, you've allocated 69 cores for cpu folding. Your total cpu cores for cpu folding should be 61 or less.

You might want to consider using just one slot for cpu folding using 54 cores which I've used on a 64 core system ... it works well and is more efficient than using 6 slots the way you're using them. You may even get more PPD. :ewink:
