Plus *he* from the Intel side is trying to improve the Rosetta code and setup so that the project benefits a lot.
*he* may get that cookie of David Baker if it does all work out ;-)
Hopefully *he* has got *him*/*them* from the AMD side to join in and help out.

iirc, *he* is doing it out of his own time, desires and not for him empolyers.

If you have read through some Who? posts the tone of them are in fun and a little jesting. You have to give Intel people a little time to have some fun, they've been down in the dumps for a while ;)

Take a look to the computer in the first place.


Yeah, but that stat is not a good indicator of performance. It this the average of only two (likely) dedicated crunchers. The reason the other chips aren't as high, is because it averages their RAC together, including the part time crunchers, multi-project crunchers, as well as those who have left the project and approaching 0 RAC.

Also, 1489 for a quad core chip is not very impressive on SETI. The #1 machine is a dual quad Mac, with a RAC of 6800+. That works out to 3400 per quad chip. So the AMD is not even half as fast per the RAC today. Now maybe it is still growing. I'll keep an eye on it.

You can too here:

and here

http://setiathome.berkeley.edu/show_host_detail.php?hostid=2877462

BTW, this host was added back in October. Are we *sure* this is the new chip??


The processor in the first place is a dual core, not a quad core.

You're reading it wrong. There are two processors (one machine each). Each is quad core.

Edit: you can read more about them here:

For that Who? would definitely deserve a cookie from the good Dr. himself. It is Girl Scout cookie season after all. Box of thin mints aka crack cocaine perhaps?

You're right Zombie.

And yes!! Who? is making an excellent work helping rosetta@home project.

I think thin mints are more addictive than crack!!! Just about the time you lose the extra holiday pounds... the evil girl scout cookies show up!

Zombie,

"Also, 1489 for a quad core chip is not very impressive on SETI. The #1 machine is a dual quad Mac, with a RAC of 6800+. That works out to 3400 per quad chip. So the AMD is not even half as fast per the RAC today. Now maybe it is still growing. I'll keep an eye on it."

According to that chart, 1489 was the RAC per CORE. Your dual quad Mac would have a RAC per core of less than 1000.

Who?,

I think it's possible that 4x4 could produce seemingly non-linear performance if bandwidth/communication on the motherboard is greatly increased. It's also possible that native quad core on a chip could ALSO produce a non-linear jump in performance. Enjoy your lead, but don't get too cocky! I, too, greatly appreciate what you do for Rosetta@Home which I consider to be the best led protein prediction project.

No. You're reading it wrong. It's the average RAC per chip. There are two chips (one machine each). Each is quad core.

You can verify that yourself by looking at the machines themselves. Links are in one of my earlier posts in this thread.
