I would also consider posting a new news item, to attract more attention from the visitors on this website, as well as readers of BoincStats and other BOINC news broadcasters.

P.S. Of course, my sincere congratulations for the whole team!


I completely agree, the 21 Jun 2010 post should also be added to the News section of the home page. This is a particularly exciting post and deserves the benefits of the RSS feed.

Great job all. :-)

Can we use this \"challenge feeling\" to increase Rosetta@home support at least till the end of CASP9? Don\'t know how... a Rosetta\'s specific challenge? CASP badges?


Oh, CASP badges, I like that idea. I\'ve been crunching though a couple of CASPs now and that would be kind of a cool things to be able to display. Something like, a distinct badge for each CASP participation. Then, maybe those badges are color coded based on crunching time. Similar to what WCG does.

Yeah, I think that would be cool.

Basically a very large fraction of the jobs you\'ll see on your machines will be relaated to casp in one way or another - i\'d say at least 60-70%.

Thanks for the info, Mike.

Very excited about CASP9 this year.

And Mike, a double \"WOW\" goes out to you all for the \"For the community, by the community\" section of your post. That is very cool news!

Happy CASP9-ing.

I just bought a Core i7 and it will be here Monday!! I will likely have lots of questions for you by the end of next week.

This is my first Ci7 and it will have Win7 so I am sure to find lots of issues.

Does anyone have experience with BOINC on Win7? Results?


Hey Paul, enjoy the new machine.

I\'m curious though why you would think you\'ll have lots of issues. I\'ve been running a Core i7 with Win7 on it, since the Beta of Win7. I have not had any issues with Win7 & BOINC. So, unless your planning some really funky setup, things should work just great for you.

As far a results, here is a link to my machine\'s Rosetta stats, if you\'re interested.

You should get a nice boost to your already nice RAC.

Happy crunching. ~Joel

Opened my PC and discovered a dustbomb. Filthy boy :(


I bet you\'ve seen an improvement since cleaning it out, right? :-)

Them nasty dust bunnies just love it inside our systems. What\'s up with that? I guess the warm temperatures of our systems provide a nice warm snugly place for them to rest & multiply. ha-ha ;-)

There has been quite a lot of work done with zinc. This is a link to an old message in RALPH when these work units were first introduced to us.

message 4286


Additional information about zinc can also be found in the sticky post: Structure prediction of zinc-binding proteins.

I\'ve had my i7 920 working about a month and a half now. I kind of like it. :-)

Here are the benchmarks as of 5/21/2009:
Measured floating point speed 3059.77 million ops/sec
Measured integer speed 9857.84 million ops/sec

You can look at the machine here.

As an example of how much more computing power we have at our disposal today, here is a laptop I decide to retire, after bring the new i7 machine online. Notice the PC was added to Rosetta on 21 Oct 2005 1:16:56 UTC. It has been crunching basically 24/7 since then, yet has only earned 71,934 credits.

The new machine caught up to the old laptop at right about the 1 month mark. Once it did, I shut down the laptop. 1 month, crazy cool.

Anyway, that\'s my i7 story. Happy crunching!

Congrats on the new machine. Nice little power house of a machine. However, something to keep in mind is that because of the power you are bringing to bear you are going to be seeing your runtimes go all over the place if you keep your runtime at 1 day.

Awhile back, the Rosetta team limited work units so they will only run 99 to 100 models per WU. If you go look at your task details for your tasks, you’ll see you are hitting that limit on most of your work units.
Here is an example:
http://boinc.bakerlab.org/rosetta/result.php?resultid=249865051

So, even though you have a Target CPU run time of 1 day, if a WU hits that 99-100 model mark before the 24 hours are up, the WU will end.

Hope that helps some.

Hey Steven,

Totally agree with Michael, thanks a bunch for sharing your experience.

And, I must also say thanks to the Baker Lab folks as well for providing such a great experience and opportunity to Steven.

Keep up the great work, all around. :-)
