I tried running OPNG for the first time in a long time on an Intel GPU. As it approached 90% the increments got slower and slower, It has finally reached 100% after nearly 2 days but is still running. I suspect that is because it has only reached somewhere in excess of 99.9995% (rounded to 100.000%).
I have checked properties and CPU time is only 55 seconds (16 seconds since checkpoint). Any suggestions, please? Mike |

I do not have A Intel GPU however you could try suspending the unit and resuming it and see what happens. Theoretically you should only lose 16 seconds of processing time

Had the same issue with one of my AMD APUs, where the job would would take a long time, and never finish. I ended up moving that machine into a profile that won't allow GPU work.

I tried Speedy51's idea and that reverted and started doing it again. I already had deleted the next WU which hadn't started and swopped profiles to ignore the GPU.
I will delete the current WU. Mike |

Before you completely take your device out of GPU work, try another work unit; or try a few weeks later to re-activate GPU work. I had trouble with single work units a few weeks ago on my Intel GPU, but the ones I got later worked flawlessly.

I had ATI GPU and occasionally run into the same issue. At first I blame it on overclocking but later realized CC_Config and APP_config played roles... Suspending and resuming also helped.
When the GPU work performs flawlessly, one OPNG will take just 3 minutes. If it doesn't work, it will be stuck at 100% for hours and days just like what you described. I'd be curious if you also overclock? What are your hardware specs? |
