[OCC] Improved Protein Folding Algorithm being Developed - Page 2

post #11 of 20
Amazing!

EDIT: Hopefully this algorithm will be shared for the greater good.

I hope you realize the algorithm was developed at McGill, whereas F@H is from Stanford.

Researchers at McGill University have been working on a new algorithm for determining the folding pathways of a protein...Do not anticipated this coming to F@H anytime soon, as it is at a different university (F@H is out of Stanford University) and still under development.

That's really interesting. I don't really care much about protein folding from the F@H competitions standpoint, but I am interested in protein folding in general. I'm skeptical about this method though. It seems to rely on already knowing a general form of a protein correlated to its chemical structure/composition, and then correctly guessing--so they've made a good guessing algorithm as long as there's enough of a library to guess from, but if you don't have a good enough starting point for the guesses (i.e., you haven't arrived at enough properly folded proteins through classical means, or if you have a rogue structure), then it's worthless. F@H will continue as is. Shortcuts might work a lot of the time, but brute force will work all of the time.

Well maybe it wont come to F@H, but there are other distributed computation projects out there, like BOINC (from Berkley) which can run, among other things, Rosetta Stone - another protein folding simulation.

So maybe this will come out under a different client, or maybe they will attach it to something like BOINC in the same way as many other projects which use that client.

Or maybe they wont need to do distributed computation, if it is as good as they claim they might be able to get all the results they need using in house hardware. Doubtful though.

No, that dead hobo + bottle of butane = best heater ever.

The PS3 is already a mighty folding machine, it deserves way more points than 1K PPD.

IIRC stanford limited its ppd because of the limitations in types of WUs it can do

We balance the points based on both speed and the flexibility of the client. The GPU client is still the fastest, but it is the least flexible and can only run a very, very limited set of WUs. Thus, its points are not linearly proportional to the speed increase. The PS3 takes the middle ground between GPUs (extreme speed, but at limited types of WU's) and CPU's (less speed, but more flexibility in types of WUs). We have picked the PS3 as the natural benchmark machine for PS3 calculations and set its points per day to 900 to reflect this middle ground between speed (faster than CPU, but slower than GPU) and flexibility (more flexible than GPU, less than CPU).

Thing is, people know what abaci are. A better analogy would be the slide rule.
