Supporting BOINC, a great concept !

Don’t worry about the memory leaks message. It’s harmless, the Windows app always shows this.

The source of your failure is further down:

07:55:53 (6200): wrapper (7.9.26016): starting
07:55:53 (6200): wrapper: running acemd3.exe (--boinc input --device 0)
ACEMD failed:
Error invoking kernel: CUDA_ERROR_ILLEGAL_ADDRESS (700)
09:42:41 (6200): acemd3.exe exited; CPU time 6346.656250
09:42:41 (6200): app exit status: 0x1
09:42:41 (6200): called boinc_finish(195)

I’d suspect either somethig wrong with the card, or a problem with the drivers.

In your case, the actual error number is

app exit status: 0xc0000135

which officially means 'status_dll_not_found'.

See the thread New version tasks failing on Windows hosts (in the GPU area), and specifically message 57353, where user jjch gives instructions for installing a missing Microsoft Visual C++ Redistributable.

I do have the same error reported on the first task that I got in months. However the app exit status says 0x1.

The corresponding task stderr file reports that

ACEMD failed: Particle coordinate is nan
06:44:59 (8516): bin/acemd3.exe exited; CPU time 27435.906250
06:44:59 (8516): app exit status: 0x1

What might have caused this?

This is my Host and that is said Task.

Bad data in the task files. Unless your GPU is so superheated that it can't do maths any more, there's nothing you can do.

All right! Thanks Richard for the blazing fast response. Card is running at a mild 53-55 degree Celsius so that is unlikely the culprit. Already feared that there's nothing I can do...

If I consider the contents of your post in the hardware enthusiast corner, I would say that the reason for the NAN (Not A Number) error in your case is undervolting your GPU.

I think that you might have been right Zoltan! Haven't been running any GPU Grid tasks for several months now and just ran with the same OC settings that proved to be working with other projects in the past... And I forgot that those tasks here are extremely demanding and power hungry, so much though that the power limit on my card (100W out of 125W) didn't cut it. Core clock boost behaviour was erratic and due to the low power limit the voltage dropped quite severely as a result of that. When you wrote your comment here, I had already withdrawn the PL on my card to get better boost behaviour. But with your explanation I now know that voltages dropped so low (~ 910mV) that the computation became unstable. Now it is running at a 1,000-1,025mV range using up to 135W at times. Thanks for your valuable comment!
