Is there a SSE3 gromac comming soon?

[matrixzen]

I was just wondering if we'll be seeing s SSE3 gromac anytime soon considering how the new P4 Prescotts have SSE3. On the other hand, SSE2 gromacs were just released and are still kinda in the testing phase. So it might be some time till we see a SSE3 gromac core. I wonder how much of a difference it would make. :eh?:

I think it really depends on how much better SSE3 is than SSE2 - the benefits will have to outweigh the time spent coding SSE3 into the core.

I would think we would see it some point though.

Yea that's what I was thinking. For now we'll just have to have fun with the SSE2 gromacs. ^_^

Perfect place for me to bring up the kick butt prescott at NewEgg (2.4A, 533fsb, 1mb L2, Prescott, No H/T, SSE3). People have been getting 3.2gig on air at stock voltage (1.4v). $122.00 shipped retail. Good upgrade processor for those thinking of SSE2 folding. BTW, 3.5+ gig with exotic cooling. Not trying to hijack your thread matrixzen.

we've had SSE2 for several years and have had gromacs for about a year. i think it will be a few years before we see SSE3 work units.

Seems like a good CPU that would do good in one of our AAR rigs. :)

I had no idea it was around that long. Sorry for stirring things up here. :-/

yeah i definitely agree... unless sse2 is such a big sucess and it isnt that hard to upgrade to sse3, i dont think that will be in the cards for anytime soon... i really dont think they would be in the mainstream till both intel and amd both had cheap cpu's with sse3. if they added it any sooner, it would be with a flag to enable it...

is SEE3 needed to make the insmells work like a AMD? Just trying to get your goats dudes, but from personal experience the AMDs churn up the Gromacs faster.

I'm sure this has been said before but tinkers are the most helpful to the scientific community, so probably SSE3 gromacs won't happen for a while. the last Dgromac i got was about 2 months ago too :(

Are you sure? I always thought it was the Intel chips that churn up the gromacs faster and the AMD that churn up the tinkers better? :eh?:

SSE/Gromacs & SSE2/DGromacs were a great success as more work was done in a much more efficient way than Tinker units. So those of us who had the hardware to support SSE/SSE2 were flying up the ranks in comparison because Stanford awarded the points based on work accomplished, not how long it took to fold the WU.

However when Stanford started force feeding large Tinkers to all, there was a revolt and some people started dumping the Tinkers in favor of Gromacs. So Stanford raised the Tinker points so they would get the same PPD for Tinkers as Gromacs. That was to stop the WU dumping. So since we're getting the same PPD for both more or less, I see no advantage for Stanford to bother with SSE3 in an effort to maximize the hardware performance for those of us with cutting edge machines.
