Code:
copy results_exported_130*.txt merged.txt
works in my circumstances. The "130*" might be different on other systems. Those happen to be the first 3 digits following "results_exported_". For me, at least, files which have letters instead of numbers in that position are "per instance" results, while numbers correspond to combined results. The numbers are needed to exclude files beginning with "backup_", which again, are for individual GPUs.

I was wrong. It's type in DOS.

 2015-06-21, 01:32 #16 TheMawn     May 2013 East. Always East. 11×157 Posts I have added my GTX 980 Ti to the TF effort. It's actually a very impressive card, and I look forward to un-crippling it by putting a proper cooler on it... For now I have a GTX 980 Ti and a GTX 660 Ti on the same system and there is a very gross throughput difference between them so I think I need to adjust something in MISFIT as a result. I came back to my computer to see that GTX 980 Ti had stalled at some point and the first thing I think of is that worktodo.txt ran out. I used the MISFIT calculator and just added both of my GPUs' throughputs (250 + 750 = 1000 GHz Days per day) and applied all the values. I think what happened is MISFIT has no way to know that one of the instances is cranking through so much more work than the other, because my GTX 660 Ti has 23 assignments queued (it usually has a half dozen or so). I set MISFIT to balance worktodo files when the row difference is 5 or more. Does this make sense as an adjustment?

Hi, Work Balance is designed to handle the differences in card throughput just as you described.

The default setting of 5 is fine in most cases. I've never needed to change it, but it was implemented back when the project was doing factoring to 72, not 75. That right there will change the physical count of assignments typically stored on your PC. To compensate adjust the re-balance value or increase the number of assignments stored on your PC to ensure there is time to get the work moved around before a run-out occurs.

Another issue is the defaults for how MFAKTC implemented workToDo.Add

(from my release notes of MISFIT VERSION 2.10.0)
Quote:

So MISFIT cannot re-balance work in a timely manner if you allow MFAKTC to sit on the .ADD file for such a long time.

Let me know how it goes.

Thx

Scott

 2015-06-21, 20:21 #18 TheMawn     May 2013 East. Always East. 11·157 Posts Okay, thanks. 5 seems to work just fine. I've increased my fetch threshold from the calculated 1250 to 1875 GHz-Days which is what the value would be if both of my cards were GTX 980 Ti's. That is still far, far less than a week's worth of buffer so there are no issues there. I'm actually still on 2.9.5. I'll have to dig back through the mfaktc and misfit notes to understand why people wanted misfit to use worktodo.add, since MISFIT kind of does the same thing already.
