Why there isn't an application of Astropulse for GPU?

Because nVidia didn't write one.

What?! Do you mean that 6.08, 6.09 & 6.10 were written by Nvidia, not a SETI@home team?

Lets say it's collaborate work but yes - nVidia did the initial programing.

I don't know what SETI@home team provided - just math principles or nVidia looked at CPU code and ported it for nVidia GPUs

P.S.
And I don't know why nVidia became NVIDIA ;)
Maybe to be noticed against the all-caps ATI/AMD

SETI@Home gave nVidia the source code to their MultiBeam application and nVidia ported the code to their CUDA architecture.

Learning to program for a massively parallel processing unit like a GPU takes lot of studious care, especially since its a very new thing in the computing world.

Its not that the SETI@Home staff are incapable of learning such an architecture, rather they are quite busy writing grants, trying to find funding to keep the project going, and keeping up with their day jobs.

Most of the advancements in GPU programming has come from a third-party team of coders known as Lunatics, and most of their efforts have been eventually merged into the main project.

The SETI@Home staff has been focusing on getting ready for the new SETI@Home v7.0 application and an app that will process data from the new satellite dish.

So yes, SETI@Home v6.08 was modified by nVidia, and team only made minor changes in v6.09 and v6.10.



As for the spellings, I'm very old school. nVidia debuted as nVidia and ATi debuted as ATi, so that's the way I write them.

It's worth noting that Lunatics is indeed working on GPU applications for Astropulse, but they're of course volunteers, so be patient.

Raistmer (one of the Lunatics crew) is working on an OpenCL Astropulse application for nVIDIA GPUs.

If the application will be released, I guess it will be published in the NC subforum.


BTW. Astropulse (also S@h Enhanced/MultiBeam) is already possible on ATI/AMD GPUs.
