I kinda get the feeling seti is falling behind in taking advantage of the latest and greatest unlike other @home projects, considering the importance of the project that should not happen.

First off, with graphics card's now featuring general purpose steam processors units and other @home project's now taking advantage isnt it time someone works on making them work for seti to, my main pc for instance features a quad core Intel extreme edition processor overclocked to 3.2Ghz which racks up around 1200+ avg credit+ if ran for round 16-18 hours of the day, however the same machine also features 2 8800 GTX's with core overclocked to 620Mhz and GDDR3 overclocked to 999Mhz (actual) in SLI, meaning there are 256 Steam Processors running at 1.2Ghz each (im pretty sure its 1.2 but wiki says 1.35Ghz each)just sitting their idling which could be utlised whilst I run seti, like seti program folks ye even working on this?

Also err just bought a PS3 to go with my x360 and I notice a copy of Folding@home just waiting for me on it, no alt os installed on it required(something I wouldnt bother doing on a console, well ok i put linux on a dreamcast once but not again lol), now I did a bit of research and from what i can gather you were in contact with them but after you sorted out the legal issues the folks who were gonna do it for you moved on to other things, well... kick sony in the teeth until there's new folks to work on it, kick up a fuss, complaign be generally a pain in the butt until they do it, and also explain seti maniac's like me would have bought a ps3 much much earlier then now had I been able to run seti on it.

Like for the mo i'll just run Folding@home on it I guess until ye folks get seti loaded onto it.

But ye just seem to be wasting the opportunities that the latest technologies bring, unless of/c you have so many folks donating their time you just don't care any more?

Clearly ATI at least would be happy to help you configure their graphics card's spu to run seti based on their past conceptions and I doubt nvidia would say no if poked as lets face any excuse to flog more stuff and show how cool their card's are, so what are ye waiting for lol?

Also ever thought of poking microsoft and nintendo to get clients working on their consoles x360 has 3 cores that could be utilised at least, (though I don't think it uses steam processor's off-hand being to my understanding a kind of dx 9.5 equiv) so no luck graphics wise but still 3 cores is nothing to be sniffed at.

Err know next to nothing about the wii's design atm as I not bought one yet but well every little count's.

Well hope this gets read - cya

SETI is Open source, and people can adjust it as they wish. The people at SETI are overworked, underpaid, and work part time to keep the project going. There is just a handful of them. They rely on donations to keep SETI alive, as there is no government or school funding.

If you look on the 3rd party download pages (I do not use them, so I don't search for them), you may find something you are looking for.

As for Graphics cards, SETI's math is quite different than some other projects. The graphics cards have been shown to actually slow down processing, per some of the things I read. So it will not always be better to use the extras.

Read around, you may get a larger picture of what is happening with people programming the project.

I'm just don't that doesn't make all to much logical sense, obvious pre-steam processor's they weren't much use but steam processor's ought to if programmed correctly be quite capable of performing well anything and i can't see how running 256 steam processor's to go with my quad-core processor would if properly programmed slow down the process as they can run independently without taxing the CPU is my understanding, not to mention having their own memory.

And being well aware of the funding issues it is however rather irrelevant I doubt every progressive @home project are full of government funded fat cat's with a full-time dev teams ... ?

And open-source should not be used as a derogatory term when it comes to programming projects like jeez it means more folks can contribute to the work not less, and I can't see there not being a good bunch of programmers contributing to seti.

And I have looked and done my research and whilst thanks for bothering to reply I'd much rather have a reply from someone with a technical standpoint within the project... hell frankly I don't really need or require reply I just hope the message trickles through to the right folks as from my a long-term seti contributer who's electricity bill is never low thanks to seti processing in comparison with other @home project it beginning to seen as seti is falling behind, there is a ps3 port of seti, in a pre-release phase but it runs on a version of linux which to my understanding only runs as one instance and is not even slightly optimized meaning instead of full use of the ps3's power ... it treats it like an old pentium iv, and as the cell processor in ps3's are 8 way processor's designed for high-end servers with one failed core (so 7) but (btw despite what im saying don't get me wrong im not a sony fanboy i'm a hardcore gamer so i'm kinda have to buy all the consoles mainly a pc gamer and my preferred console is x360)

Like that project need's some help me thinks, and yes i'd like to see some serious attempts at using everything that could potentially maximize the use of the hardware I dedicate to the project, and others like me can't possibly disagree, whilst somewhat competent in a couple of programming languages i don't have the time to donate to seti, and frankly with power of the hardware I do run seti on most of the time I've done the best I can.

There are a couple of problems with using graphics cards. The first is that there is no standardization for a programming language (yet). The second and more serious for S@H is that getting data out of the card back into the computer is slow, and apparently, S@H needs to retrieve a fair amount of data from the card. Again, this later could change in the future.

It would also mean a bit of change to BOINC as the processing would no longer be symmetric - some tasks would run on the CPU and others would be slated for the graphich card.
