Whee. Back to #140 on the world list with the G5 but still.
My RAC has slowly risen although I'm not quite sure why.
For me a Mac Pro purchase would likely be years off since
I just got this last summer. Oh well.

Interesting stuff, Karl.
Since SETI will be down for a good while, as it seems, it might be a good time to make our systems available for testing any new worker developments. Alex, anything new from your side? My quad feels lazy...

I had to do some rather extreme work on my old Athlon box to make it SSE comapatible.
I'm running the Chicken of Angnor's optimized SSE Windows client on it now,
my old motherboard had an old BIOS that didn't know about SSE since SSE
did not exist on Athlon chips at the time so I flashed it and updated it and now
run an SSE client on it. Oddness.
Anyway:
Results for computer
Here's my G5 again. Times are ranging from 1000-8000 seconds,
pretty good for a 2.5 dual. I've been briefly inside the top 100 again
which is great - I'm currently 111 but I'm sure this is short lived -
those Mac Pros are looking like monsters.

hey
Karl may already know, but some Mac news pages today healined with the CPU in the current Mac Pros to be replacable with Intels new Quad Core CPU. that means, we could possibly have a 8 Core Mac Pro sooner or later hehe

Long time no see, E.T! Welcome back! Did you do any benchmarking (ref-WU or so) before and after the Core 2 Duo install?

Nope just plug the new CPU and start crunching, maybe later..

As for what's been happening on my end, here's a prerelease version of v7 for Intel. This was as far as I could get for now, since halimedia temporarily needs his Mac mini back for other things. It's also (finally) compiled with ICC and IPP, which gives a little extra boost. In general, no miracles between v6.1 and v7, but a noticeable speed gain nonetheless.
Try it out and let me know what you think. I wasn't totally finished implementing new tweaks, but hopefully it should be stable and correct enough to be usable. The real version of v7 for PPC will be soon to follow, since none of my PPC dev tools are Intel-specific.
And please, please, if you have a Mac Pro, run v7 and post links to your results! (It doesn't seem like anyone has one yet, though...)

Hi Alex,
Looking forward to the ppc version 7. One question - can I use the intel version on my windoze XP Pro - intel P4 machine?
Thanks
K.

No, binaries are operating system-specific. As for Windows, there's always Simon Zadra's clients. I don't think I have the additional tools necessary to roll a fast binary on Windows, anyway.

Thanks Alex - needed to check there had been no change.
I found Simon Zadra's site Seti@Home optimized science apps and information and started useing that binary on my PC.
Cannot make a comparison as the Mac is crunching seti-enhanced 5.13 and the PC is crunching 5.15

Alex:
Changed to the V.7 yesterday at noon EDT. Average cpusec/credit was 142 using V.6 NG, and it's now 124 cpusec/credit. MBP 2.16 GHZ core duo. http://setiathome.berkeley.edu/resul...hostid=2546291
Now if you could just do something about the high RA WUs...
On V.6, I got this for performance 7396 cpusec 64.35 cred = 115 cpusec/cred
2056 cpusec 12.53 cred = 162 cpusec/cred
on V.7, I'm getting 7152 cpusec 64.25 cred = 111 cpusec/cred
2316 cpusec 12.52 cred = 185 cpusec/cred
From looking at some other results, this relative slowness of the high RA WUs doesn't happen on AMD machines, but does on Intel and PPC
Thanks for the great speedups for our Macs!

It looks like E.T has updated his C2D Mac mini to run v7. Take a look at the times he's turning in--that's the new Core architecture for you. Keep in mind that that chip is only running at 2.16 GHz on a 667 MHz FSB.
Now imagine a Mac Pro at 2.66 (or even 3.0) GHz on a 1333 MHz FSB.

Alex: can you give us a brief overview of what v7 does over the previous
version? What about PowerMacs?
I've got a really odd idea about running the current version in an unusual
configuration - stay tuned.

That's unbelievable! E.Ts mini is almost twice as fast as mine (w/ original 1.66 GHz CoreDuo). Wicked!!
