Even with some assistance from Google, I'm not quite sure I understand what you're saying -- that FFTs have sizes, but those sizes are not measured in bytes, so I should express it as 3M, but not 3MB? If that's all, why didn't you say so?

That was precisely what I was saying, and hence a big deal it
of out to make I wasn't.

I passed German "O level" in 1965, and am grateful for it, although
predictably the several agreeable German volk I have met speaky Englisch
besser than I Deutch do.
Soon after we started to learn the "word order" (age~12) my best friend
and I would in Englisch that order always speak.

Though James is usually spot-on, I'm afraid that this time you've spotted that he's inserted a "B" where there should not be one.

James,

Perhaps you've momentarily forgotten that FFT sizes are customarily measured by the number of floating-point "digits" rather than bytes. (That's why the mersenne-aries site lists "768K", not "768KB", for instance, as an FFT size.)

- - -

In Prime95, the FFT "digits" are each a double-precision FP number, spanning 8 bytes.

So, in GIMPS, an FFT of size "1024K" or "1M" occupies 8MB, not 1 MB, and a "3M" FFT occupies 24MB.

If some other FFT software were using single-precision FP for "digits", there a "1M" FFT would occupy 4MB and a "3M" FFT would span 12 MB. That shows why FFT sizes are not listed in MB or KB: because then one would have to also specify the size of each FFT "digit" in order to get a proper FFT picture.

4MB would contain 1M digits of single-precision FP, but only 512K digits of double-precision FP, or only 256K digits of quad-precision FP.

A nice, diplomatic way of saying I don't know of what I speak. Which in this case is entirely true.

Thanks to your cogent explanation, I now understand why I was wrong.

These sayings into German for me please translate:

"Of which we cannot speak, we cannot know" (Wittgenstein)
"We can know. We must know" (Hilbert)
"Manuel, this wasn't a proposition from Wittgenstein: I said
GET THOSE DEAD PIGEONS OUT OF THE WATER
TANK BEFORE THE HOTEL INSPECTORS ARRIVE" (Basil Fawlty)
"That's my sunlounger. I arose earlier than you and reserved
it by placing my towel thereon". (Tourist)

(Nuff quotes for now - Ed.)

David

PS Don't think I mentioned the War or Geoff Hurst did I?
Well I may have done once, but I think I got away with it.

This may not exactly fit in this thread but I didn't want to start yet another thread for a minor topic.

My i5-750 is OC'd at 3.2 Ghz.
It has been doing DC for all of 2012 so far.

The per iteration timings in the 1344K FFT range have been a very consistent 20Ms on all 4 cores.

Just recently it started a 1440K FFT on 1 core and 1344K FFT on the other 3 cores.

The 1440K FFT timing went to 20.25Ms; about a 1.25% increase as expected.
The timings on the 3 1344K FFT cores DROPPED to 19.8; 19.55 and 19.45; decreases of about 1%, 2.25% and 2.75%.

Could I be correct in extrapolating from this that LL/DC performance is slightly better if you mix FFT sizes across the cores.

Severe lack of Ivy Bridge + Linux in this thread. Its not a big improvement per-clock over Sandy Bridge, but you don't need exotic cooling either since the TDP is 20-30W less than equivalent Sandy Bridge!

It looks to me like you might get better results if you turn off hyperthreading (at least in prime95. Everything else will be more responsive to normal usage if it is on while prime95 is running).
2 threads on one physical core is slower than 1 thread in your benchmark.

Looks to me like 6 threads on 6 physical cpus might be better. Basically this means turning hyperthreading off.

Or just running 6 threads and leaving HyperThreading enabled, assuming other work will be done on the machine and it's not a dedicated Prime95 box. At least that's what I do.

4x AMD Opteron 6176 (4x 12 cores - 4x 32 Go DDR3)

http://pastebin.com/MZdGjv8A (too long to post it here)

I get every time a Segmentation fault at 8K FFT on 17 threads.
Does anyone have the same issue?

Does anyone have the same issue?

Is it possible that the way the ffts are divided something as small as 8K can only be divided into <=16?
Does anything smaller work with 17 threads?

As you can see 4K, 5K and 6K worked without any problem...

henryzz · 2012-11-15, 23:25

Sorry I hadn't looked at the link.
The times for less than 8k seem pretty constant as if only one core is used. 8k actually slows down significantly with 16 threads. 8k is probably just the first multithreaded run(i.e. the first test with >16 cores). I would suggest pming prime95 in case he hasn't already seen this yet.

Works fine for me too, but not for the Benchmark.
I'm using a i7-3770 (4Cores+HT) with

AffinityScramble2=02461357

setting using only four cores for Prime. Hence don't touching the HT cores.
That works fine for 2 treads per test by under 10ms/Iteration for 51.5nn.nnn exponents.

But when running the benchmark, Core 1,2,5,6 are used. So 4 Threads on 2 Cores are used.
The Affinityscramble seems to [EDIT] spoil the benchmark. I'll have to comment it out to run it on core 1,,3, 5, 7.

A old Pentium M laptop, where there is no cpu "model"... it's just has MHz...does anyone remember these?

Yes indeed. I am still using my 1300MHz M now. I even posted a benchmark for it in the 100Mdigit thread.

And one more time. This is at 200x24=4800MHz. It survived modest amounts of torture testing in different modes. Temp on TT peaked at 65C with a Cooler Master Hyper 612. I have no intention of doing real work at this speed. I just wanted to see the numbers. The CPU is reasonably productive at stock, and "Summer is Coming." (HT to GRRMartin)

Comparing the last 2 benches there is quite a difference at the same clock rate. The difference is sandy vs haswell. Nice

Below are benchmarks for a i7 4770K with DDR3-1866 at 4.3GHz.
Prime95 stable at 1.25V, using a Corsair H110 watercooler.

HWMonitor reports a 141W power draw on the small FFTs torture test.
However, realworld running of 4 simultaneous tests on M6xxxxxx is ~115W.
On my sample at least, pushing to 4.4GHz requires 1.27V to be p95 stable.
At that level, power draw reported is over 150W+!
A bit uncomfortable for 24/7 operation, so I'm going to stick to 4.3GHz.

Was virtually the same on Windows vs linux.

I guess 28.1 will fix that

prime95 v28.1. i3930K at 4.2GHz, 8x4GB @ 1600MHz (DDR3 1600, CL9, 1.35V), Corsair H100. 169 days uptime (we moved). Fedora 16. Built in April 2012, used prime95 and other programs to ensure good overclocking and temps. I love this machine, though it does generate quite a bit of heat when going full bore. I don't like core temps to go above 60C when all cores are loaded.

I use it for lots of other development, not prime95, so I keep hyperthreading on since it's helpful on almost every other application. I'm not going to reboot to turn it off, but I did try setting CpuNumHyperthreads=1 in local.txt (turning it of in the BIOS would be a better comparison). The small FFTs were consistently slower on the 1-thread version, but once past 1024K it seemed to make little difference. On the other hand the 6-core 8192K FFT result was slightly faster with a 10.020 average.

The reason you are struggling to keep below 60C these days is because they aren't designed for that. They are designed for much higher these days. 80C might be a good aim these days. My CPU would die from that heat though(Q6600 G0).

I wouldn't call it struggling -- it's running at 4.2GHz vs. stock 3.2GHz. My 3770K is also 4.2GHz (3.5 stock so pretty tame) and I have it running a little hotter. 60C for BOINC climate prediction, ~68C for Prime95 small FFT torture test. I could go higher but extreme OC isn't as important to me as stability and reasonable power use (measuring with a Kill-a-watt, once past the easy overclocking I saw power use go up dramatically with every small rise in core speed).

Lots of heat: using the UPS to measure, the whole system (monitor off) is 159W idle, 286W prime95 blend, 376W small FFT test. My perl/GMP work at the moment gets it to 326W.

Looks like the Q6600 G0 that this replaced was at 3.2GHz and 50C. The Q6600B3 in my spouse's computer (still chugging along after 6 years) only got to 3.0GHz before hitting 60C.

Justifying the power bills to an environmentalist spouse is the real trick :).

Here's my daughter's machine I put together last night: i5-4670 3.4GHz using stock cooler, completely default settings. 93C (!) on small FFT stress test, and I'd hate to see it in the afternoon when that room is 10+ degrees hotter. 2x4GB RAM (DDR3, 1600MHz, CL9, 1.5V), Asus Z87M-Plus uATX MB, Windows 8.

petrw1 1976 Toyota Corona years forever! "Wayne" Nov 2006 Saskatchewan, Canada 1001001010111₂ Posts	DC timing anomaly This may not exactly fit in this thread but I didn't want to start yet another thread for a minor topic. My i5-750 is OC'd at 3.2 Ghz. It has been doing DC for all of 2012 so far. The per iteration timings in the 1344K FFT range have been a very consistent 20Ms on all 4 cores. Just recently it started a 1440K FFT on 1 core and 1344K FFT on the other 3 cores. The 1440K FFT timing went to 20.25Ms; about a 1.25% increase as expected. The timings on the 3 1344K FFT cores DROPPED to 19.8; 19.55 and 19.45; decreases of about 1%, 2.25% and 2.75%. Could I be correct in extrapolating from this that LL/DC performance is slightly better if you mix FFT sizes across the cores.

henryzz Just call me Henry "David" Sep 2007 Cambridge (GMT/BST) 7·29² Posts	It looks to me like you might get better results if you turn off hyperthreading (at least in prime95. Everything else will be more responsive to normal usage if it is on while prime95 is running). 2 threads on one physical core is slower than 1 thread in your benchmark.

henryzz Just call me Henry "David" Sep 2007 Cambridge (GMT/BST) 1011011111111₂ Posts	Looks to me like 6 threads on 6 physical cpus might be better. Basically this means turning hyperthreading off.

henryzz Just call me Henry "David" Sep 2007 Cambridge (GMT/BST) 7·29² Posts	Sorry I hadn't looked at the link. The times for less than 8k seem pretty constant as if only one core is used. 8k actually slows down significantly with 16 threads. 8k is probably just the first multithreaded run(i.e. the first test with >16 cores). I would suggest pming prime95 in case he hasn't already seen this yet.

db597 Jan 2003 7·29 Posts	Haswell @ 4.3GHz Below are benchmarks for a i7 4770K with DDR3-1866 at 4.3GHz. Prime95 stable at 1.25V, using a Corsair H110 watercooler. HWMonitor reports a 141W power draw on the small FFTs torture test. However, realworld running of 4 simultaneous tests on M6xxxxxx is ~115W. On my sample at least, pushing to 4.4GHz requires 1.27V to be p95 stable. At that level, power draw reported is over 150W+! A bit uncomfortable for 24/7 operation, so I'm going to stick to 4.3GHz. --- Compare your results to other computers at http://www.mersenne.org/report_benchmarks Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz CPU speed: 4002.13 MHz, 4 hyperthreaded cores CPU features: Prefetch, SSE, SSE2, SSE4, AVX, FMA L1 cache size: 32 KB L2 cache size: 256 KB, L3 cache size: 8 MB L1 cache line size: 64 bytes L2 cache line size: 64 bytes TLBS: 64 Prime95 64-bit version 27.9, RdtscTiming=1 Best time for 768K FFT length: 2.995 ms., avg: 3.017 ms.
