I read about some new F@H developments this morning on slashdot.


"...we will likely be able to attain performance on the 100 gigaflop scale per computer. With about 10,000 such machines, we would be able to achieve performance on the petaflop scale." screenshot video


"We are beta testing the ATI GPU client software internally at the moment and will likely announce an open beta in four to five weeks (end of September)."

"Which GPUs will be supported? We have not made any final decisions on this issue. However, our software will likely require the very latest GPUs from ATI (especially now that the newest ATI GPUs support 32 bit floating point operations). Previous work of ours used NVIDIA GPUs as well, but we have now concentrated on ATI GPU's as they allow for significant performance increases for FAH over NVIDIA's GPU's (at least at the current generation). Our GPU cluster has 25 1900XT's and 25 1900 XTX's. We find a considerable performance increase of 1900XT's even over 1800XT's, due to the architectural differences between the R580 and R520 GPU's. Our code will run on R520's, but considerably more slowly than R580. We're very much looking forward to trying out R600's."

Intel on Mac

"Coming soon.... 2-3 weeks...

(typed from the intel mac devel box)

p.s. the v6 client won't be as elaborate as planned, but it will be universal. v7 will have all the goodies."

Gone but not forgotten. said:
exciting but this is going to use A LOT of power, especially with new generations of GPUs possibly approaching 200watts
Watts the problem when you want to be first? ;)

People have been calling for the Cell processor to be used for folding. GPUs obviously have really great floating point capabilities and they can even speed up poor (s)Tinker code dramatically.

Of course, with Vista following Mac OS X in using the GPU for certain effects, that GPU is going to be busy.
