How do I do it? I'd LOVE to know when the checkpoints are done, it would make pausing much more efficient instead of now waiting to about .40% to pause as I used to do ~.11 then now .25% and now that will move back a few whole percent some times, so I'd like to pause right on a checkpoint.

Better yet, a "Pause at next checkpoint" would be a wonderful addition to the GUI!

Core updates are automatic. If you're assigned a project that uses FAHCore_21, the latest version will download (unless you already have it) and the project will sta

"Pause at next checkpoint" has been suggested before, and it's on the list of suggested enhancements, but active development of FAHClient has been suspended so you probably won't see any enhancements soon.

Checkpoints intervals differ by project. I've seen 2%, 2.5%, and 4%. This is what I do to pause shortly after a checkpoint:
1. Get the number in the ID column of the Work Queue that the slot is currently working on
2. Go to Start > FAHClient > Data Directory
3. Navigate to the work folder and open the slot with the # from step 1
4. Go to the numbered subfolder and open log.txt
5. Look for this section and note the "Checkpoint write frequency": 6. Go to the end of log.txt and where you see the following, a checkpoint was written: 7. Close log.txt and monitor progress in FAHControl until it reaches the next percent that will trigger a checkpoint
8. Pause the slot

Code: Select all

[ Entering Main ]
  Reading core settings...
  Total number of steps: 2500000
  XTC write frequency: 50000
  Checkpoint write frequency: 50000 (2%)
  Number of frames per WU: 50

6. Go to the end of log.txt and where you see the following, a checkpoint was written:

Code: Select all

Performance since last checkpoint: 3.341067285 ns/day

7. Close log.txt and monitor progress in FAHControl until it reaches the next percent that will trigger a checkpoint
8. Pause the slot

That is some serious dedication to pausing without going backwards again, thank you, I'll give this a go!

Here's an alternate method (GPUs only):

If the WU is just starting, don't worry about it.
If it has been running for a while, use steps 1,2,3, and the first half of 4 above.
5. Look for files viewerFrameX.json where X is: Top, 1, 2, 3, 4, ... (here "Top" means zero)
6. Subtract the times of two adjacent files and add that difference to the time of the last one in the series.

You likely have the new core already. Another nice feature the dev team added a few versions back is the core version number is diplayed in the log as the core starts running.

Right.

Look at the log when a new WU starts for a project that uses FahCore_21
