BU WUs seem to fall of the GPU at the end

[Maxwell]

I just want to see if I'm nuts or something...

I'm running Bitcoin Utopia on a couple crappy ATI cards I have at work. It had been working fine for a while, but lately, it seems like the WUs are falling off the GPU. They'll crunch up to 90-95% really quickly, then the last 5-10% goes at the pace of a snail wading through molasses in January.

Is this normal? Should I be doing something differently? My credit output on this has dropped by around 80%...

It may be a coincidence, but a daily restart on my Win7 7790 and 6870 machines practically eliminates hangs.

One of the machines, I restarted late yesterday and have the same issue...

Mine just plod along right to the end ... no fast and then slow up. I've had no errors except on Cuda cards.

I looked at a laptop today, and it had a WU hanging out at 100% after running for 19+ hours, and still had yet to finish. I shook my fist at it, then did a project reset. We'll see how that goes.

Did you see the recent thread about disabling Benchmarks? I wonder if that might help at all...

Thanks for that - didn't see it, but it certainly couldn't hurt. I added it to both machines.

I have BOINC benchmarks disabled in my cc_config file and BU still hangs occasionally, though less with daily computer reboots

Oy. Stupid Work Units.

After an afternoon of futzing, I've figured out that the portion of the CPU that's being reserved for the Bitcoin work unit is not being obeyed by some of the other projects I'm running. The other projects (Rioja, Beal, CAS) taking up all the CPU, and leaving nothing in reserve to feed the GPU.

So: is there an app_info file out there that will let me reserve an entire core to feed the GPU? I don't want to have to give up CPU crunching on this laptop if I can at all help it...

You need app_config.xml, not app_info.xml. Much easier.
