Does anyone know how long Rosetta@Home will be handing out CASP9 WUs? Will they be coming out until the end of July, mid-August, end of August?

Thanks.

The CASP8 summary stats links is hard to understand, can someone do a writeup that explains how Rosetta did in comparison to everyone else, anything exciting that happened, stuff like that?

The server also seems to be out of work, there are 0 queued tasks and none of my clients are getting any work.

Does anyone know what they will launch?


So it is the 25th and still the same message, did they launch anything today?

if i remember correctly...you can\'t compare amd and intel clock speeds because of the way they process data. so amd\'s 2 ghz is just as fast as intel\'s 3ghz, but rated slower due to the way it processes data.


You can\'t compare clock speeds directly which is why I said, \"might be faster\" but with such a high clock-speed difference (50% in the case I was talking about) it could push it ahead.

My point was though it\'s not he two separate or native quad that really matter, even to the enthusiast. It\'s how fast it does it.
If Intels is faster (for what they want) they would buy that no matter if it was 4 individual CPU stuck together for the price they wish to pay. so native, none native.. who cares as long as it does it job ;-)


Just take a look at us for example. If you had the choice of a 3GHz Intel non-native quad-core or a 2 GHz AMD native quad-core, what you really care about is if I have 4 BOINC threads running, which one will produce more results in the same time period.

The Intel might be able to finish WUs faster with its 1GHz clock advantage on a single-core system, but if the quad-core could only produce a 3x speed-up vs the AMD with a 3.8x speedup, you would have to see if the extra GHZ can make up for the \"loss\" of one effective core.

But the difference is not as big with a quad-core system, it is more the 4-socket systems where you get 16 cores on one machine that you would really start to see the scaling difference I would imagine.

Post:
Are you running this on XP or Vista?

For some reason my Vista 5.10.20 client always has WUs listed as high-priority and the strange thing is that it takes turn working on all of them. So it will work on one for a while, then switch to another for a while, then switch to the next, not finishing one of before going to the next.

Intel has been filling a need for efficient powerful CPUs for virtualization. Next month they will be releasing a true quad core @ 45 nano.


I don\'t think so. The 45nm CPUs to be released next month I believe are still 2 dual-cores sandwiched together. The true quad-cores don\'t come until the next iteration which is the end of 2008 I believe.

well, at 2Ghz, the compiler does not make any difference ...


It probably would on systems that have 4 and 8 cores running. Will the Barcelona processors even support SSE4 or does SSE4a mean something else like a SSE3+?

It will also be nice when new Intel after Penryn comes out with native quad-core design and on-die DDR3 memory controller. That will finally give us some scalability with hopefully clock speed as well.

One die or 2 dies , does it make any difference? does it? This NON NAIVE Quad core Core 2 design allowed the price of the Q6600 to go below 300$


If it doesn\'t make a difference why did Intel bother changing the design from 2 dies with the Pentium D to 1 die with the Core 2? With the Core 2, each core can share parts of the cache right? Wouldn\'t a 1 die quad-core benefit from the same thing between all 4 cores and have faster inter-processor communication?

I understand that Intel will eventually release a one die quad-core design so there must be some benefit to using that?!?!?

[This V8 with 2 Xeons 45nm Penryn is a Pretty fast beast, I count on you to read or come to IDF
Nothing Naive into this quad cores


Is the Penryn quad still just two dual-cores sandwiched together or is this a \"true\" quad-core? If not, what is the name for the real quad-core and when is that supposed to be available?

Thanks.

Yes one of them thanks. Looks like there is a patch to add to the client to fix it as well.

In general though there is nothing wrong with the client, most likely less wrong with it than the older versions now since it\'s is all just development upon the older client and nothing major has really changed.
The major changes are scheduled for the 6.x.x releases.


Did they fix the problem with 5.10.7 that broke all the proxy support?

I upgraded and now PROXY support seems dead. The HTTP or SOCKS proxy no longer works for me on more than one machine. Is proxy support working for anyone in this release?

Back to normal now


I thought so as well, it downloaded a few files but then stopped again. So I think there is still a problem, stuff is going out from the server in trickles.

Same problem here, hopefully they will wake up on the West Coast soon so they can kick the server or something.

I\'m getting a list of files to download and my uploads are working fine, it just doesn\'t actually download the files...


Next 20
