Message 1565695 - Posted: 1 Sep 2014, 14:17:37 UTC

Sometime last year I had an issue whereby the mouse would "stick" or not move when commanded for a while, and it only happened whan the gpu was set to crunch. I turned off GPU crunching, but there was chatter on here about it at the time.
Since I upgraded the PC earlier this year (but kept the ATI 6950), I restarted GPU crunching, even to the point (after installing Lunatics) to doping 2 wu's on the gpu. To be fair, I get roughly the same amount of glitching with 2 wu's as I did with 1, but I'm getting fed up of it now. Replacing the gpu isn't an option.
Currently on Catalyst 13.12, later versions gave me issues so I swit6ch back.
Can anyone suggest anything i can try that might relieve the problem, or am I stuck between a rock and a hard place, ie crunch & glitch, or no crunch?

Are you monitoring the GPU temps? It sounds like the card was/is overheating. Also are you using any command line options in the commandline.txt file?

Temp wise, the card seems fine. and no command line options with anything.
Like I said, I'm sure there was a discussion last year about this, from what I remembered only ATI cards suffered, not NVidea. But I don't think there was ever a definitive reason/solution offered.
If it continues to bug me, I'll just switch to cpu only, otherwise I might do some damage to the pc <grin>

thanks anyway.

Do you have the same problem when running AstroPulse tasks? My series 6 cards have always suffered from the MultiBeam Screen Stutter. So, I don't run MultiBeams on them. Never had any trouble running APs.

To be honest, I couldn't tell the difference between AP & MB, it runs whatever Seti sends it ;-) But it happens a lot, usually every few minutes.

Number of tasks completed	0
Max tasks per day	32
Number of tasks today	0
Consecutive valid tasks	0
Average turnaround time	0.00 days

AstroPulse v6 6.04 windows_intelx86 (opencl_ati_100)
Number of tasks completed	8
Max tasks per day	295
Number of tasks today	0
Consecutive valid tasks	195
Average processing rate	678.80 GFLOPS
Average turnaround time	1.18 days

AstroPulse v6 6.04 windows_intelx86 (ati_opencl_100)
Number of tasks completed	1
Max tasks per day	298

Consecutive valid tasks	198
Average processing rate	401.79 GFLOPS
Average turnaround time	1.72 days

It appears you haven't run very many APs on your ATI Card.
None recently. Did you install the AstroPulse App when you ran the Lunatics Installer?
You seem to be missing the AstroPulse v6 (anonymous platform, ATI GPU) entry.
If you installed the AP App, set your preferences for AstroPulse v6 only and by tomorrow your cache should be low enough to grab a few APs.

Not sure, but |I can re-run Lunatics. Won't dsetting prefs for v6 also affect the cpu tasks as well, I thought Version 6 was now defunct, or am I getting a tad confused? (not difficult)

SETI@home, MB, is v7
Astropulse, AP, is v6

Disabling MB in your prefs will effect CPU & GPU. If you re-run the installer choosing only the AP app for the GPU then you can leave MB & AP set in your prefs. As the GPU will only have an AP app to use & will be download MB tasks.

If you want to run MultiBeam on the CPUs, just install the MB CPU App and the AP ATI App. Best to wait until you work through all those ATI MBs though. I run APs on both the CPUs & ATI cards, so, I don't have that problem. AstroPulse Version 6 will be around until it is replaced by AstroPulse Version 7.
Here's my ATI machine, http://setiathome.berkeley.edu/results.php?hostid=6796479
As you can see, it is happily crunching AP_v6. Even if it is down to the Horribly Blanked ones. It will be refreshed tomorrow :-)
