3 times AK V8 result for this WU and pending Credits?!

The 4th result will be from AK V8 also.. ;-D

wuid=267143201

An opteron vs p4 vs Core2 , All agree there's one spike, but I guess that one must be borderline somehow. As two are running identical code I can only suggest platform variation or other random effects there. I think you'll find this kind of situation extremely rare.

Or some validator bug. It would be very useful if some of SETI team at Berkeley check this WU with standart app.

The last (4th) AK V8 result is back and all got the Credits..


538.69 sec. = 8.98 min. difference between Q6xxx @ 2.4 and @ 3.14 GHz
AR=0.447513 - Credits=50.5973958333333
I like my OC.. :-D

EDIT:
Ops - the 2.4 have WinVista.. :-(

...
wuid=267143201

While it's still there, have a close look at that result's stderr.txt output, you will see it did not detect the spike the others did, yet they still agree. That's an example of a borderline signal again IMO ... must be a very sensitive area I guess.

Can someone tell me what the difference between SSSE3 and SSSE3x versions is? Also mine is reporting "Build 41" but I have seen others with "Build 42"... is that important?
I really appreciate these optimized versions but I find the naming confusing; I was using:
V5.15 'Noo? No - Ni!' Revision: R-2.4V

Now I use:
(v8-nographics) V5.13 by Alex Kan SSSE3x Win32 Build 41

Stock version:
setiathome_enhanced 5.27 DevC++/MinGW

Hi There,

1) The 'x' came from a directive placed in that particular build that was intended for 'Xeon' based Macs, and happened to show improvement on pretty much all 65nM Core 2 variants (When ported to Windows). So it no longer applies just to Xeons , and the name was shortened to 'x' to save confusion that would be generated if we called it 'Xeon'. It merely controls the stride size in some critical loops that particularly seems to help in machines with RAM/CACHE/FSB Pressure. That build is fastest on many pressured SSE4.1 45nM systems also.

2) Alex's code for the Macs was based on earlier Seti@home Sources version 5.13, Prior Lunatics code was based on 5.15. Not much difference between those two stock codes, and neither optimised variant necessarily has much of the original code in it other than basic framework stuff.... So that just becomes a number.

3) Stock is now newer, but small incremental changes such as variable credit multiplier and Multibeam capability were implemented in the optimised applications as they were introduced into stock, meaning there's no immediate necessity to worry about a major source 'merge', of course Version 6 is on it's way, so perhaps that'll be a different story .... Then there's AstroPulse ;D

Hope that Helps,

Jason

Hello all,
I'm using the AK V8 app with xp pro 64 bit. My question is will it work with 32 bit xp pro? This is a great app and knocks an hour or better off WU time.
Thanks, Jack

Hi there,
There are separate 32 & 64 bit downloads for the Windows AKV8 port.
- The 32 bit version will function on both 32 bit & 64 bit XP (& Vista)
- The 64 bit version is for 64 bit windows only.

Thank you Jason,
I messed up and installed the 64 bit on an amd machine with 32 bit xp. I wasted six WU's oops! I should have asked first, I figured thats what it was when they got done in two seconds and had client errors listed. I'm all straightened out now.

Sorry if there is an answer to this already, but I have been searching on this for the past couple of hours in vain...

I have noticed that this user, hansR, has a fleet of what appears to be Northwood-core Pentium 4s running a Linux SSE2 port of the AK application. Have a look at the stderr output of one of the recent results to see what I mean.

Is he using a custom-built application or has someone released a Linux SSE2 port while I wasn't looking? Because I would very much like to run the new AK application on one of my hosts which is also a Northwood Pentium 4 (ie SSE2). I appreciate any information on this.

Found at Crunch3rs linux 32bit page

My goodness, how can I be so blind? I check Crunch3r's pages all the time.

Well, thanks for that! :)

Found a 40% reduction in time from 5.21 to 5.28 on my AMD Opteron 1210 running SuSE Linux 10.3 at 1.8 GHz. But how comes it finds also SS3 instructions on my CPU? I am only aware of SS2 and installed the SS2 AK V8 application.

Download and run cpuz and it will check your cpu and report what featuresets it will support.

EDIT....I do not run Linux....can anybody confirm that cpuz works under a Linux OS?

EDIT 2...A listing of the Opteron 1210 I found on Tiger Direct shows SSE3 capability...

This is an excerpt of the result of command hwinfo --cpu in Linux:

Of course I might install the SSE3 application and see if it works. That would be a litmus test.

You could try that.....
You are running with a very small cache, so if the app does crash and trash the few WUs you have, it would be a minor problem.....
Let us know how it works for you....try the AKV8 SSE3 AMD/Intel version...

In Linux, SSE3 is sometimes indicated by pni (Prescott New Instruction I think) so the SSE3 app should work

I'm running the SSE3 version under Linux on my X2 4000 system w/no problems. hwinfo shows pni on it. Under Windows, cpuz shows SSE3.

SSE3 app works on the Opteron 1210 but the CPU time is same as the one obtained by the SSE2 app. Thanks anyway for the info, I am surprised that both AMD and SUN, which built my workstation, do not mention SSE3.

Hi, I am back.

I posted to this thread almost 2 full months ago.

Thanks for the info to upgrade the app, I am running 5.10.45 on q6600, not oc'd but with factory oc'd 8800 gt vid cards in a case with 7 fans, and vista 64.

The CPU temps out at 36c. But here is the problem. About every two days, the machine freezes. No rhyme or reason. It can freeze up while I am using it, when only Boinc is running, and either during the day or over night.

Now I wasn't sure if it was the machine or BOINC, but now I am convinced it is something to do with BOINC. I have had the machine running for 1 week now without BOINC running, Vista blocks it at startup and I have to manually override vista to get it to start, so it was easy to not let it run. No freezes at all, runing 24/7 for one week. I have restarted BOINC less than 1/2 hour ago, so we will know later tomorrow if it starts freezing. There are no warnings or errors in the event log for Vista.

The freezes are irritating.

But to let you know, the Work done has climbed from just around 300 in May 2nd, 2008 to 135,000 on June 30.

Which is faster, AK V8 64-bit or 32-bit? And by how much?

Which is faster, AK V8 64-bit or 32-bit? And by how much?

64 Bit Application (64 Bit Windows OS required) is roughly 10% faster depending on the hardware, than 32 Bit running on the same 64 bit environment. On the same hardware, 64 Bit Windows seems to run the 32 Bit Application roughly same speed as the 32 Bit OS does.

As they say, Your mileage may vary.
