Some tasks that use the MacBookPro's ATI GPU have been abnormally
terminated for several days, then I investigated it.

This computer is also equipped with the Intel GPU, so it seems that
things that are delivered for this Intel GPU and normal CPUs are
handled without problems.

Examining the logs etc seems to be exceeded elapsed time limit. The
following is an excerpt of the information examined.

So I was cancel this ATI GPU type tasks.

You might stop processing the intel gpu tasks. They slow the whole system down significantly. I agree that 14 hours is way to long for any gpu task to run. It might have been "looping"? I get that kind error "every once in a while" and I am running Intel/Linux and Windows. So it maybe "the luck of the draw" rather than hardware issues.

One thing that stands out to me is this line:
Device peak FLOPS 79.88 GFLOPS
Now, this value looks to be very low for a GPU, but others with more AMD/ATI GPU knowledge may be able to comment on that....

At least one "signal" was found, so there was some processing going on, but "not as we know it".

Questions
- were you trying to run multiple tasks on the GPU?
- have you just updated the drivers?
- has this computer "worked well" until the last few days?
- are you running any video-intensive tasks?
- have you got sleep/hibernation activated?

You might stop processing the intel gpu tasks.

It's means BOTH GPU stop? I don't know how to stop for only Intel GPU.

It might have been "looping"?

May be looping. The task start, soon remain estimate time increase by increase.

I get that kind error "every once in a while" and I am running Intel/Linux and Windows. So it maybe "the luck of the draw" rather than hardware issues.

Before several day, all task process were worked. So I have no idea about other OS nor hardware issues.
But I have a plan that is OS update. I will try this after OS update.

Questions
- were you trying to run multiple tasks on the GPU?

try to run with a single Intel GPU task and a single AMD GPU task.

- have you just updated the drivers?

No, I think. But I will try to OS update. Used OS version is MacOS Mojave (10.14.4 Beta), so I will soon retry after OS update.

- has this computer "worked well" until the last few days?

Yes

- are you running any video-intensive tasks?

No

- have you got sleep/hibernation activated?

Sleep set up is only display.

I think this issue is close , beecause :

No, I think. But I will try to OS update. Used OS version is MacOS Mojave (10.14.4 Beta), so I will soon retry after OS update.

After update macOS Mojave from Beta 5 (18E215a) to Beta 6(18E220a), ATI GPU type tasks process are work without any error messages.
Already about 20 tasks were finished.

It's means BOTH GPU stop? I don't know how to stop for only Intel GPU.

On the Seti website under your profile you will find "Seti@home preferences". If you look under there you will find a "Intel gpu" checkbox. Make sure it is un-checked and Seti will stop sending Intel gpu tasks. Don't forget to save the change.

It may take days for your system to finish the processing of the intel tasks but once it does, it won't process anymore intel gpu tasks.

I could not find out any "Intel gpu" checkbox. But I want use all available computer resources for BOINX, I DON'T want to un-check.

Anyway, I already did update from macOS mojave Beta 5 to Beta 6, then ATI GPU type tasks process works fine. So I does not want or could not back to Beta5.

You need to turn the "Use Intel GPU" option off from your web preferences:
https://setiathome.berkeley.edu/prefs.php?subset=project
Save the changes then wait a few hours for the changes to work through the system to your computer.
(There is a quicker way, but this is the simplest to explain)
