I recently updated BOINC to 7.2.28 (x86). This evening I was working on my PC, doing some maintenance, when the system significantly slowed down. I therefore manually suspended the GPU (snoozed). However AstroPulse continued to work (per review of Task Manager) even while I was using the PC, despite having it set to only work when not using the PC. I finally had to close down BOINC in order to finish my work.

I then restarted BOINC and AstroPulse did not restart (I assume because I was using the PC--and GPU set not to start or continue to work while computer in use). No delays in computer's function as of yet, but AstroPulse not yet an active process per Task Manager. Apparently it stays as an active process, once started, even if suspended.

Just concerned and wondering why AstroPulse GPU continues to work when snoozed, while S@H v7 GPU does not.

That is a known issue for 8400 GS GPUs, they are practically the slowest Cuda GPUs out there, it is thought the app is always in a Critical section on those slow GPUs, and so can't be suspended,
there are later Nvidia OpenCL Astropulse apps in testing with a newer api that may fix this, in the meantime you may wish to deselect Astropulse v6 in your setiathome preferences.

Thank you very much for the background information. Relieves my mind that this is a known issue. Will keep your advise in mind.

I started a thread on this in February 2013.
http://boinc.berkeley.edu/dev/forum_thread.php?id=8215
My thread was prematurely closed, so I can't post updates there.

The "astropulse non-stopping bug was STILL occurring today in Boinc 7.2.28.

I just updated to 7.2.33 and will test it for the bug.

Boinc version 7.2.33 still has the non-stop bug.

I let the pc sit idle for a couple of hours and Boinc started SETI@home. When I returned and tried to use the pc, the machine was slow and chunky, as it has been when astropulse kept running, after it should have stopped.

When I opened up the Boinc manager, I could see one of the SETI@home tasks STILL counting up progress percentage.


I looked in the Process list in Windows Task Manager and saw 3 SETI@home programs running. This time they were not identifying themselves as astropulse. The offending setiathome program had cuda32 in the name. I recall that name from the astropulse entries in the Boinc log. So, it appears that astropulse has been renamed to setiathome...cuda32.exe.


When I manually stopped the setiathome...cuda32.exe process, the machine ran at normal speed again and the Boinc manager showed that the non-stopping process now showed an error message.


Here's the log from this afternoon.

Does anyone know if this has a chance of being fixed?
If not, the solution is to disable astropulse.

Thanks,
Eric

S@H v7 7.00 Cuda 32 is NOT the same as AstroPulse. An entirely different app. run on your GPU rather than CPU. I suspect earlier in your log you'd see this wu exiting repeatedly, with no results, thus causing your system to overwork. (I've got an old Pentium 4 running XP that has problems with cuda 20s, doing as I mention above. I have to abort these apps.)

I also have the AstroPulse issue where it continues to run after supposedly being suspended. A GPU issue with my old NVIDIA card, explained by Claggy after my original post.

Good luck!

OK. It sounds like we have 2 issues now - cuda32 and astropulse?

No more problems with slow chunking since I disabled Astropulse and the use of my nvidia 8600GT GPU!

Use CPU
Enforced by version 6.10+ yes
Use ATI GPU
Enforced by version 6.10+ no
Use NVIDIA GPU
Enforced by version 6.10+ no

Run only the selected applications
SETI@home Enhanced: yes
SETI@home v7: yes
AstroPulse v6: no
