Feature Request: Pause at next checkpoint

Postby Crawdaddy79 » Sat Apr 11, 2020 3:24 am

Hello Folding Team,

I use the pause feature a lot. Sometimes because I want to do something else on my PC that requires cycles, sometimes because I just want this corner in my basement to cool down. Either way, I would like a better way to pause progress so that X amount of work isn't lost and has to be redone. Currently I have the CPs set to five minutes, but even 4:59 worth of waste seems unnecessary to me.

I would like for another button to be added, "Pause at next checkpoint". This would encompass the checkpoints of every folding slot.

This way I could click the button and futz around until everything is paused, and then do my thing.

Also there's a whole "my PC crashes when it runs at 100% for too long and it comes back reporting BAD WORK_UNIT" story that I'm not going to go into too much detail about.

Agreed, I would like this too.

I think it checkpoints when you pause it. The UI will go back to the last whole percentage point, but when you unpause it the "Completed steps" will show that you've kept your progress since then.

I wish that were the case, Frogging101, but check out meh logfile of when I arbitrarily paused, waited a minute, then unpaused.

0x22 went from 68% to 65% after unpausing.

Code: Select all

Interesting. Your CPU slot did save, though:
Code: Select all
03:16:22:WU00:FS00:0xa7:Completed 16250 out of 125000 steps (13%)
03:17:03:FS00:Paused
[...]
03:17:21:FS00:Unpaused
03:17:22:WU00:FS00:Starting
03:17:22:WU00:FS00:0xa7:Steps: first=7375000 total=125000
03:17:24:WU00:FS00:0xa7:Completed 17072 out of 125000 steps (13%)


Also, I've not seen a WU lose more than 1% before. I thought it at least checkpointed at every %. How odd.

GPU WUs pause at set percentages that are set by the researcher when the project is set up. Depending on the project, typical values are every 2-5%.

CPU WUs running on the A7 core write out a checkpoint at the time interval set in the client through FAHControl. Depending on how it is paused, the A7 core will attempt to write a checkpoint then as well.

That figures, actually, since GPU computing generally processes data in large chunks for efficiency.

Generally speaking, if you're using the CPU, folding would hardly impact whatever tasks you're running on your CPU as folding priority is very low while most other tasks are set at a higher priority. I understand if wanted to pause the GPU slot since you may encounter screen lag. You can reduce/eliminate the screen lag by disabling the hardware acceleration on the application (if it's supported) and/or disable Windows animation.

That's an indication of something else. I have folded on my CPU at 100% for months without issues. The only time I would restart was due to the monthly Windows updates and apart from that, it would fold day and night without crashing. If you would like us to investigate, please do share your log and as much details as possible about your system setup and usage.

The other day I needed to pause the GPU slot for a minute because I needed to move the electrical plug for the laptop (old battery not strong enough to sustain a full load), and I lost around 45 minutes of work

Hence my! general recommendation: never ever pause a GPU slot.

That's an indication of something else. I have folded on my CPU at 100% for months without issues. The only time I would restart was due to the monthly Windows updates and apart from that, it would fold day and night without crashing. If you would like us to investigate, please do share your log and as much details as possible about your system setup and usage.

Agree about the CPU impact being minimal and 100% reliable when pegged at 100%. It's the GPU that I have issues with. It seems to become unstable if it runs at 100% for too long (60 - 90 minutes OK, 120+ minutes, not OK) - but that's digressing.

CPU WUs running on the A7 core write out a checkpoint at the time interval set in the client through FAHControl. Depending on how it is paused, the A7 core will attempt to write a checkpoint then as well.

This is good info. Thank you.

Yeah no that's not realistic

A log notification about hitting a savepoint would be cool. :)

That would be (I would guess) the easiest update that can solve this problem

I haven't looked at any of the new covid projects but before that when I checked 2.5% was pretty much normal, a safe bet would be to stop after multiples of 5%.
