Re: Rice results updates

Wow sounds great.. if WCG isnt supporting GPU at that time are we going to use normal CPU processing... and any idea when we might see some more?

thanks for the updates

Re: Rice results updates

Hello lhhung - Nutritious Rice for the World Scientist

Reference: lhhung [Aug 22, 2010 3:17:15 AM] post

Greetings.

I feel like singing after reading your update.. as one line of a Deep Purple song goes, "It's not the kill, it's the thrill of the chase!" However, it's the promise of a kill that powers the chase.

I'm excited to see scientists chase that GPU-based implementation. I'm excited to see scientists chase the science and technology that is behind the eventual kill. My ATI card is always ready to fire up for the chase!

Another thing, I'm sure you have heard of the approach to grid computing via tapping into human intelligence through video games instead of the typical approach of algorithms/iterations executing in a computer. In a way, that is similar to why Kasparov beat the BigBlue supercomputer in the early goings of a chess match sometime 1990's until BigBlue caught on and learned how Kasparov 'does his algorithm' and BigBlue won. I say scientists everywhere do this approach and not just rely on 'dumb' computers -- and GPU-based crunching seems to be the ticket to go there smile.

Good day

Re: Rice results updates

Nasher:

Yes, it can work just with CPU processing though this means drastically lower numbers of candidate structures predicted per sequence. It still works but will be less accurate.

andzgrid:

You shouldn't be surprised that scientists get excited over stuff - most of us are just big kids.

For protein folding I've always thought that using human intervention was a good approach. We've do it ourselves all the time to sanity check the structures. It's a lot harder than you think and the human is wrong a lot of the time. Where I think it has value is in adaptive algorithms where the human sees patterns developing and wants to explore certain sub-structures with different sampling methods or energies. Even if it is just a more sophisticated algorithm, understanding how humans fold proteins should help develop better computer algorithms to do the same thing - just like the grandmasters programming Big Blue were able to incorporate and adapt to Kasparov's methods...

Re: Rice results updates

the big question is any idea when more work will be showing up.

Re: Rice results updates

Ihhung, thanks for all your efforts.
As an old faithful Nvidia enthusiast I am on the starting blocks to use the Fermi based boards whenever you are ready. smile
The Fermi chip is the first really designed for number crunching, I hope you will have your software compatible with it. biggrin

Re: Rice results updates

When one tells something (the source), then it being heard and told on (second source), and then it being told on ("hear say" twice divorced), it soon turns from "we're running this in house" to "it will launch on WCG in the near future". No, my reading is: There are no plans at all to bring GPU RICE crunching to WCG.

sorry.
