	I too will add my voice to the chorus of Thank You's Thank you guys for all your hard work. Now how do we get Alex to look at optimizing some of the other BOINC projects like Einstein? :-) ____________ BOINC blog

	Correct, they do. I have a couple P4 laptops, Toshiba 2435-s255, that I cant seem to find the information on. Also, both the Athlon and Phenom, are running Vista. Is Vista supported? I could only find mention of earlier Windows versions. Use something like CPU-Z to check the older CPU's where it's less certain. And there are x64 version of the V8 app and I'm running them on Vista x64 and Xp64. ____________

	A big " THANK YOU " to all the people involved in the porting !!! Kurt Just wait a few days, Your RAC will or maybe already is gonna surprise You, Mine sure enough has, It's going up and I'm not sure where It'll stop. :D I've shaved on average of about 32 minutes per WU from 2.4V, AK_V8 ROCKS! Now we're cookin, Pedal to the metal guys. ;) :D I, for one, have had nothing but mid AR units (between 0.4 and 0.5) since the new App was released. This band is where the new Apps have greatest impact (not accidentally as I understand it). As and when we get some VLAR or VHAR WU's, the improvement, while still very impressive, is not quite so mind-blowing. Don't expect the gravy train to keep going full tilt :) F. @ Joker @ Fred The new app works like a charm ! Unfortunately I`m only feeding my PENDING cache at the moment - Therefore my RAC is on the same level as usual, although I spend about 1/3 time less for each wu. But that`s no big deal, I`ll sit it out ! Happy crunchin` Kurt ____________

Right now I sit at 60k in pendings, and RAC has increased slightly. ____________ Clk2HlpSetiCty:::PayIt4ward

	THANK YOU. Just installed it last night. My cruch time were about 1:20 per wu. Now they are getting done in about 55 mins. Well done guys. ____________

	My crunch times for 74 point work units went from over 14k seconds, down to 6.6k seconds. Way to go with that app optimization!!!!!!!! ____________

	Fred W said: From the charts I published I was quite confident that the SSSE3x and SSE4.1 Apps were much faster than the SSE3. I have run through over 100 WU's using the SSE4.1 on my Q9450 since yesterday (all in the same AR band) and it looks like there are still a lot in the same AR band coming next, so I have just swapped to the SSSE3x App to do a direct comparison. I can provide additional support for your confidence from a small experiment on two Conroe-class systems. I tried downgrading my Q6600 and E6600 from the SSSE3x to the SSE3 ap versions overnight. By chance the Q6600 has caught a number of VLAR work units at exactly .008341 Angle Range (on the low end of VLAR). The advantage of the SSSE3x version is clear and substantial. SSE3 5 results, average 4798 CPU seconds SSSE3x 17 results, average 4094 CPU seconds The distribution of individuals is very clearly different, not even close to overlapping at this sample size. On the same host, I happen to have caught a single exact Angle Range in mid-AR also, .408612. Here the advantage of SSSE3x was much smaller: SSE3 5 results, average 3248 CPU seconds SSSE3x 11 results, average 3100 CPU seconds The distribution of individuals here is not nearly so impressive as at VLAR, with plenty of overlap, and room for doubt on the large-sample result. In case it matters, this Q6600 is running 25% SETI, with the rest being the current Beta Einstein Windows ap. My E6600 caught smaller comparisons of the same populations, with very similar results (large, unambiguous SSSE3x advantage at VLAR, much smaller, possibly questionable advantage a mid-AR, no results for SSE3 at VHAR on either host). As it also runs 25% SETI, all these ran with a current Windows Beta Einstein on the other core. I'm convinced enough of the SSSE3x advantage on these hosts to switch back, so won't be producing more data on this point. If I understood Jason's comment about stride reduction and memory conflict correctly (for the tweaks bearing the Xeon label), it is likely that were the Q6600 running four SETI's rather than one SETI and three Einsteins that the SSSE3x advantage would be yet larger. ____________

	I have installed it did I install the right one as it says Core 2 and I only have one cpu You have the right app........ And judging from the last result you returned, your crunch time has dropped almost in half......very nice. ____________ ****** "Ask not, what your kitty can do for you.

	I have installed it did I install the right one as it says Core 2 and I only have one cpu Yep, to explain that peculiarity with a piece of nonsensical technical gibberish: The AMD/INTEL SSE3 build, actually uses "generic" core2 optimisation compiler flags ( /QxO ) and whatever the code runs on, it was still hand optimised by Alex for Core2 type machines ... So there you go, you're running a core2 optimised app on a p4 as it says ;D (It's the "generic" bit that limits it to SSE3 & let's it run on AMDs too) Jason ____________ "It is not the strongest of the species that survives, nor the most intelligent that survives.
