Astropulse on GPU's?

(1/5) > >>

Hey,

I was thinking to myself after seeing a few AP work units in my cache, wondering if it'd be possible to run astropulse on a GPU instead, increasing efficiency and getting them reported faster. If it's possible are there any down sides to it?

To my understanding, GPUs are not well suited to the type of math AP does. They might be useful simply as extra cores, but would probably be slower than a real CPU core.

If you have ATI GPU then yes, it's possible.
For NV GPU it's possible too, but if you own NV GPU better use it for MB crunching.

Do you know how long it takes an ATI GPU to process a AP WU?

Look at my own host on SETI beta/main for example :)
http://setiweb.ssl.berkeley.edu/beta/results.php?hostid=39394

Don't take too seriously high-time results - they from currently developing app and will be improved, lower values are more typical.

EDIT: Elapsed:17,347.96   CPU:2,018.83 is smth typical for my Quad9450 with HD4870 GPU.
