...

in 2015 when intel adds its new instructions including the

SETI R1,R2,R3

I very much doubt Intel would bother to do that. Much better Marketing to have us have to expensively buy their thousands of instructions of complexity instead!

Unless that is AMD fills the niche, or the ASIC or FPGA people blaze a new way... ;-)

instruction that can run a typical WU in 60 sec's using the 1 atomic instruction

SETI R1,R2,R3

should the WU be given

1) More credit for being more efficient
2) less credit for using only 1 atomic Flop
3) credit calculated by some other method

What we have at present is in effect something that averages down to 'option 2' as a greater proportion of new machines use the new super fast instruction.

I advocate an 'option 3' and 'option 1' whereby the number of bit flips needed to get the job done on a 'standard processor' is rewarded. Then if you go quantum, you get rewarded with a higher RAC for being more efficient. If you go GPU, you still get a higher RAC for going brute force fast even though only a fraction of your real world bit flips will count.

Go ASIC/FPGA for total efficiency :-)

According to Joe (who I'm assuming is an authority on the issue) there is absolutely nothing optimized about the new stock V7 CPU apps. Why do so many of you keep saying it is?

It's the same old stock V6 CPU app with a bit of AVX voodoo.

The new credit scheme is GHETTO!

It's been fun for the last five years, but it's time to go. The latest version is kicking my poor old 2006 Mac Pro's butt. Fans running fast whenever SETI is working which never happened before. I'll be replacing the machine soon and I'd like to keep it in operation until then.

Maybe time to clean them. I'm running v7 on my laptop from 2005, no difference in CPU temperature at all, just like on my desktop system.

Sorry, but that was a lot of work for nothing. The answer is in this very thread:)

What part of this sentence...

The v6 and v7 CPU apps are about the same speed when doing v6 tasks, with a small advantage to the v7 version on hosts with AVX capability.

...is tripping you up?

And do you realize that v6 and v7 WUs are now built with the same source or is that tripping you up? So of course V6 WU and V7 WU run at the same speed doing the analysis common between the two, it's running the exact same code.

Facts

The standard CPU app, both the current V6 and V7 app, are using source that includes the Alex Kan optimizations that were the root of Lunatic's optimized seti_enhanced apps of the past.

It also now uses an open source FFT library that is AVX aware. Some previous optimized apps used the Intel optimized FFT package which was problematic due to open source licensing problems. I have no idea how the two library's compare in performance but both the standard and current Lunatic's apps now use the same library.

The the same analysis is done on a V6 WU as a V7 WU except the V7 includes an auto-correlation analysis pass.

Just get a couple video cards, mid-range cards work perfectly fine in my upper 4x pcie slots. CPU crunching is so last decade.
If I didn't run out of APs, I would be twice as high.

Look here for an idea of which cards to get, OSX and Graphics Cards
Why should I be penalized due to only APs working on my cards?
:-)

Can the "scientists" that manage this project explain why "Flopscounter" (under Task details) appears to be showing a lower flops count for v7 work units compared to enhanced work units ... has there been analysis to determine if v7 work units are correctly counting/reporting (I use that phrase loosely) flops.

Are you talking about the Average Processing Rate? That's a per fix time measurement used to estimate how long a WU is expected to take. <flops> in the app_info does the same thing except APR is dynamic, adjusting for each "completed" WU. The estimated time is used so you don't get over assigned your queue setting for days, assuming you aren't at the 100 WU limit for CPU/GPU.

So same flop count divided by longer elapse time equals lower APR. I believe that number is calculated by dividing the average flop count by the average elapse time of valid WUs.

But you aren't going to listen to me.

Running the new application with the AVX support bumpped by CPU temperatures up by 3-5°c.

That might be because of you are using AVX now, I doubt he is doing that with his 2006 Mac. 3-5°C is also nothing to care about much unless you already had temperature issues anyway. But his description of the problem is just that his fans are running faster than before, that's not an issue actually, not for the machine at least.

"Time is simply the mechanism that keeps everything from happening all at once."

Best evidence is the rewards given my dual card machine. My faster card is consistently given fewer points than the slower card. Aren't they supposed to be about the same?

Faster means fewer points? It's broken. Say it ain't so...

The chances of a response from the 'scientists'
that could change anything is some minute fraction
of zero.

Really, does somebody think they would purposefully
expose themselves to the haranguing and abuse that they'd
receive from posting in this forum?

Keith, no I am not talking about average processing rate.

Then where do you see this ""Flopscounter" (under Task details)" you are talking about. Because I don't see anything in BOINC manager or any of the data driven web pages.

I simply want to know what you are looking at and where.
