That difference in how the FX-4100 and FX-8150 react to prefetch distance is still fascinating.

For J54 I've modified the test framework again, each test will show the minimum time taken by one iteration. That will give some indication of how much variance there is.

I've also added an e variant for avx_fma4 which is exploring the capability doing 128 bit operations rather than 256 like all the other avx tests. I expect it to be faster than the existing SSE3 test both because it's using fma4 and because with avx enabled there are 3 operand forms of the instructions. With old-style SSE3 an operation like a = b + c actually had to copy b to a then add c. The 3 operand form does it in a single operation. I doubt the e variant will challenge the 256 bit versions, but it's possible. An AMD engineer chose to have the GCC autovectorizer produce 128 bit AVX and FMA4 for Bulldozer v1 because that outperformed 256 bit code on some of the SPEC benchmarks.

Again difference from 4100 to 8150. 8150 is more consistent though.

I can't remember if arkayn runs with any frequency changing settings enabled, either turbo or C&Q, but find it strange that his 4100 chooses so differently, when mine choose avx_fma d8 every time, and with almost the same exact timings.

I am running strictly stock speeds with my FX-4100 and have the system set to performance in the CP.
12GB DDR3-1600 Ram
GTX460 & HD7750

That could possibly explain why results fluctuate more on your system.

My 8150 is residing in an ASUS Sabertooth 990FX, and is locked at 4.5, with CNQ and turbo turned off, as well as any other power saving states (C1E, C6). The SRQ/UNB/L3 cache is running at 2.4Ghz. Memory is at 1866Mhz, but it is cheap ram, with relaxed timings (9-10-9-27-48).

Locked clock will produce more predictable results, because the CPU cant decide to change speeds during tests.

But looking at mintimes on your 4100, it does seem to prefer d8, as that produces the fastest mintimes, so Josef's inclusion of mintimes are helpfull indeed.

Hi there,

I have the new Game-Machine for my brother under my desk. Basic config:

i7-3770 @ 3.4GHz / Sabertooth Z77 mainboard / 8GB of DDR3-1600 memory.

My 8150 is residing in an ASUS Sabertooth 990FX, and is locked at 4.5, with CNQ and turbo turned off, as well as any other power saving states (C1E, C6). The SRQ/UNB/L3 cache is running at 2.4Ghz.

But looking at mintimes on your 4100, it does seem to prefer d8, as that produces the fastest mintimes, so Josef's inclusion of mintimes are helpfull indeed.

Just restarted to check my BIOS and disabled Turbo and C1E, so there should be no major discrepancies now.

Well, now it doesn't prefer d8 (if it ever did) anymore, but at least its consistent with what it chooses.

Results are more stable it seems.

arkayn · « **Reply #144 on:** 25 May 2012, 01:44:00 pm »

Actually, my system has fairly consistently preferred a, but d8 was usually a close second.

KarVi · « **Reply #145 on:** 25 May 2012, 01:52:11 pm »

Yes.

Still it is a bit puzzling, that mine definately prefers d8.

Perhaps my SRQ/UNB/L3-cache is taxed harder, because of more cores asking for work?

But this test is singlethreaded (as far as I know), so that shouldn't be the case. Maybe the clockspeeds of L3 or memory play a role here?

Anyhow the differences are small, so I can live with whatever Josef chooses to work with.

Another thing, it is daunting to see an i7@3.4 comletely dominate my 8150@4.5. AMD has much catching up to do.

My i3 is also cruising past the FX computers.

Just proves my point

It would be nice if Josef had the time for a more specific AMD build, now he is running AMD specific FMA4 anyway.

A build made to take advantage of any strengths, and avoid (m)any weakneses, specifically for BD, would probably perform even better.
I'm not a programmer, but I have read a little of what Agner Fog has written about optimizing code, and it seems there are many do's and don'ts for Bulldozer, and they don't allways correspond well with the do's and dont's for the i-series.

I don't now how AMD specific he is doing things, and AMD specific development would probably require that he had access to a BD based system, and I don't think he has that. The current remote testing is a bit slow

Under the circumstances I actually believe he's doing an excellent job.

But I hope he keeps up his efforts, I´ll keep an eye and test all that I can, to help him in his work.

Although there are still puzzles from the tests so far, with the attached J55 I've added another dimension to the tests. J54 and earlier have been doing full Mebisample chirping as needed before doing Gaussian, Pulse, and Triplet finding. For cases where that's not needed, AK_v8 becomes more cache friendly by subdividing. So I modified all the chirp functions to support that, and J55 does testing at 128K and 32K in addition. The timings ought to be about 1/8 and 1/32 of the full length tests.

I do appreciate the testing, and am glad the Ivy Bridge system reacted like other Intel CPUs. Whatever form of dispatch is eventually used, keeping the number of code paths low will be more efficient.
