I don't usually use a SS, but that will be fun to fart around with from time to time.
I hope they get it released before too long.

PS: I only wish I was a big hitter. I only have two computers.... I just tend to stick around like a stain on the rug once I get comfy with a project. This one (Rosetta) has got a lot to offer. (Boinc has been a nice surprise too! :shocked: )
Their forum is GREAT (of course, some of you know what I just went through in another place so this is a breath of fresh air to me.
I do have a question. I'm trying to do multiple projects (I want to pitch in with TAS a little bit) and anyway, I set it at 500 and 100 for the resource share and answered the preferences question to switch projects every 60 minutes. My question is, Does that 60 minute answer only apply if I had set equal resources (100) for each project?
TIA

I'll go for the simple one now, what is an SS ???????
Rest is too complicated ATM
The thread linked to above is refering to a Rosetta Screen Saver (SS) so you can watch stuff while the project runs.
It doesn't really "do" anything, but sounds cool anyway.
If you follow the link Spacehead put up, then click on the tiny little link at the top of the page that leads you to the post that is being replied to, you can see some screen shots of it.

Hi Sid, it (from what I read ) does do something ,which is unusual, for a screen saver
here!
I'm not usually a fan of screensavers but I read this in the thread
"Hi, I'm a researcher in David Baker's lab and one of the people working on the screen saver graphics. We're very excited to have BOINC users watch our simulations in action. We believe you may even be able to provide us with feedback about the behavior of our algorithms. To that end, we'd like to make the graphics show as clearly as possible what is happening during the simulation. And we'd like to make it possible for you do discuss with us, and each other, features that you observe.
Some aspects of protein folding are quite amenable to human intuition. On some of the other message boards there have been discussions of the important features of proteins. From a visual perspective we can think of proteins as molecular chains that fold into specific shapes. A very common way of viewing proteins is as a "backbone trace." This view strips away most of the atoms, and simply shows the path the chain takes through space.
This reduced view allows one to see the overall "fold" of a protein, without worrying about the details of where every atom is. We propose that this would be the first kind of representation we would use on the Rosetta screen saver. This view would be colored so that you could see and talk about specific regions of the fold.
What you would actually see on your screen would be the repeated search (using a different random seed) from an extended chain to a compact folded structure. This will take a few minutes on a typical computer. This structure may or may not be close to the right fold, and may or may not have a good energy. We are trying to understand what features of search allow us to sometimes get the right fold.
We are interested in details you notice during this search process. At first this might be things like "The red and yellow part always lock in first, while the blue part flops around." Or, "The structures with the lowest energies always have the green part fold last."
I anticipate that we can evolve the screen saver, particularly as people become more experienced looking at it, to provide more technical information. As David says, it will also be easier to discuss the nature of our search algorithm once you see it in action.
I will try to post a screen shot"
And this
"dgnuff,
Yes. In our trial runs we can have very fast frame rates with very little impact on the actual scientific computation. One neat thing about Rosetta is that (in some stages of the algorithm) the structure of the protein changes lot per second. It is fun to watch it jiggle around on the screen in real time.
Jack"
If they can manage graphics with very little performance hit then I'm all for it
