New AstroPulse applications for GPUs.

Is there any way to throttle the load put on the GPU?

Yes, this program (TThrottle) will let you choose the Max temperature you want:

I'm using a Toshiba which evidently has issues with drivers. The verification tool will not even load.

Is this your laptop? (Toshiba Tecra® R850-S8530):

If it is - look here (there is 'AMD Display Driver(06-29-2011; 131.17M)' - but probably it is with 'high CPU usage bug' for OpenCL):

Need more AP... need more AP... need more AP! :) I have two ATI 5850's set to Xfire in my i7 950 box. They mow through the AP units in short order. Sometimes the GPU's are fully loaded 80% or better. On some AP units they run at between 12% ~ 20% or so, kind of odd. 90% of the time they are waiting to get their silicone on more units. Still both GPU's get AP WU, the i7 950 never gets AP WU... well done team!

Isn't it possible to cut down on the AP splitters so they don't finish long before the MB's are done?

.... and can be underutilised (though less often, nowadays) between AP batches.

Hey~

I'm relatively new on BOINC (joined a few days ago), and I have a problem with OpenCL tasks.

I only got 1 OpenCL task (90 tasks in total for this computer) through BOINC. The server doesn't return any other OpenCL task for me, even if I force the refresh. The log event says "Scheduler request completed : got 0 new tasks".

It's frustrating, since my GPU computes 16 times faster than my CPU for MilkyWay@Home (05:47 for GPU versus 01:37:23 for CPU ). I own an AMD Radeon HD 7800 which support OpenCL 1.2, with Catalyst 12.8 (had nothing too for 12.6).

Any idea ?

Windows Version : 7 Professional x64
BOINC Manager version : 7.0.28

EDIT : nvm, just discovered the server status page. So no Astropulse task for the moment. Too bad :(

WTF o_o All the remaining time of my tasks are speeding up. I was at 3+ hours on a task (which is now computed with my GPU thanks to Lunatics), it ended in less than 3 minutes (fastest got computed in 02:10). It computes more than 60 times faster on my GPU, and at least 2 times faster on my CPU (one of the tasks is going at least 10 times faster). Tasks computed by the GPU are computed a lot faster than Astropulse tasks.

Something seems wrong. We are far away from the estimated 8x computing speed acceleration for the GPU. Even the CPU is computing at an insane rate. I guess I'll have to keep an eye on the "Invalid" page.

Anyway, thanks for the download link for this software. I'm impressed.

They are all valid. Impressive.

Temperatures are OK
- Max 77°C for CPU cores
- 62°C for GPU

I've seen worse :)

I've set the following rules :
- > 80°C for CPU, throttle
- > 75°C for GPU, throttle

For this type of analysis, you need to compare apples with apples. Not all tasks have the same runtimes. Runtimes vary according to the angle range of the telescope at the time of recording. In addition, some tasks might exit early if they're very noisy - usually as a result of terrestrial interference.

I have been having problems lately with GPU processing. AstroPulse v6 6.04 (ATI_opencl_100) has been causing error messages about my AMD video driver not responding and a restart being successful. It does this about every few minutes (all input locks up and the screen goes blank then slowly comes back. I am running 3 monitors but not displaying the SETI processing graph on any screen. Usually it only involves 2 monitors (connected to the graphics card - the other is connected via USB). Also the elapsed time resets to zero during these episodes. The other thing is that I do not have my local preferences set to use the GPU and Boinc is running one more task than my local preferences allow. It only does this when the above mentioned astropulse program is available. I will revisit my web specified options to see if I can turn off using the GPU. My video card is an AMD Radeon HD 6570. At first I thought I was having either video hardware or software problems but quickly narrowed it down to astropulse being the culprit.
