New Multi-Threaded Pi Program - Faster than SuperPi and PiFast

[poke349]

In an attempt to answer the call for a decent multi-threaded pi program, here's what I've come up with:

y-cruncher: Multi-Threaded Pi-Benchmark for Multi-Core Systems...
2011 World Record for the most digits of Pi ever computed - 10 trillion digits
2010 World Record for the most digits of Pi ever computed - 5 trillion digits

60x faster than SuperPi on Core i7 for 32M Pi.
5x faster than PiFast 4.3 on Core i7 for 10m Pi.
32M Pi in 6.273 seconds on 4.53 GHz Core i7 980X.
1 billion digits in 3 minutes, 28 seconds on 4.8 GHz Core i7 3930K.

Latest Version: v0.5.5.9180 (fix 2) Now with support for AVX instructions!
Backward-compatibility is maintained for x64 SSE4.1, x64 SSE3, x86 SSE3, and x86.

The benchmark is also available for 64-bit Linux.



Warning... This program can be more intensive than prime95.
Version 0.4.3 stress test runs hotter than both prime95 and Linpack on Core i7 with HT enabled.
We've had our first dead motherboard as a result of this program.
So watch your hardware if your overclock is borderline unsafe under prime95 and Linpack.

This is NOT another HyperPi-like program that runs multiple computations to satisfy all cores.
This program uses multiple cores to compute a SINGLE result - much faster.

Multi-threading improves computation speeds by up to:

• 4.3 x on Core i7 920 (4 cores + Hyper Threading) ----- (Updated 10/23/2009: v0.4.3 scales better than v0.4.2 on Core i7.)
• 3.9 x on Phenom II X4 (4 cores)
• 3.7 x on Core 2 Extreme QX9770 (4 cores)
• 7.0 x on 2 x Xeon X5482 (8 cores)

Note: Speed MAY NOT be consistent between versions.
Each version may be faster or slower than the previous. (usually faster)
However, I will make it very clear whether or not each new release is speed consistent with the previous version.


Benchmark Results: Where do YOU stand? Post your benchmarks!!!
(Last updated: 6/19/2012)

Versions of different speeds are color-coded accordingly:
Grey = v0.2.1 - v0.3.1, 0% - 8% faster than v0.1.0 depending on # of threads.
Black = v0.3.2, ~2% slower to 3% faster than previous depending on computation size and # of threads.
Red = v0.4.1 - v0.4.2, ~2 - 6% faster than previous.
Magenta = v0.4.3 - v0.4.4, 0 - ~20% faster than previous.
Yellow = v0.5.2, 2 - 12% faster than previous.
Orange = v0.5.3 - v0.5.4, 10% - 15% faster than previous depending on computation size.
Green = v0.5.5, ~1% faster without AVX. 5 - 15% faster with AVX.
Blue = v0.6.1, ~10 - 15% faster


Color-codes for different class of systems:
Green = Single-Processor
Purple = 2 Processors
Red = 4 or more Processors

Underline = Not Overclocked


All times are in seconds.

Hi guys I ran a comparison too computing pi to 32m with a core i7 920 @ 3.2ghz

superpi: 660.614s
pifast 4.3: 77.50s
quickpi x64: 32.95s
y-cruncher x64 16.692s

and not shown on the screenie, quickpi 32bit took 34.35s



y-cruncher = full of win

[poke349]

wth... XS reverted...

Anyways... New version is out! This one has benchmark validation and anti-cheat protection!!!

[ChaosMinionX]

Cool


Checking it out now

[spdycpu]

wth... XS reverted...

Anyways... New version is out! This one has benchmark validation and anti-cheat protection!!!

Wish I had saved all the results posted in this thread.

I'm curious again about a few things:
Do you think you'll maintain a result list?
In the Validation.txt output could you include the time?
Could you bring back the ability to change the number of running threads?
Maybe add an efficiency number (cycles per digit for example)?

For example my work system is an E7200 (Penryn dual core 2.53GHz), here are the results with the x86 SSE3 binary:

Processor(s):   Intel(R) Core(TM)2 Duo CPU E7200 @ 2.53GHz
CPU Frequency:  2,527,040,841 Hz
Thread(s):      2
Digits:         25,000,000
Total Time:     56.4712 seconds
Checksum:       46d5028e60d7bba608077b159b3d8a4b

If we do...
( (CPU Frequency * number of actual cores) * seconds) / digits calculated
we get 11416.4 cycles per digit. Would it be something worth adding you think? The CPD timing would likely only be valid for a set number of digits, but, if people like to test one size (100,000,000 for example) then it could be useful for comparison and tweaking.

What do you think?

[poke349]

About half the old posts are still in the Google cache. Should we grab them and re-post?


Result List:
I'll start by listing them all on this thread (on my first post.)
I'll keep track of the top few times on each size. But I won't split them into different binaries (x86 vs. x64) because that would be too much. (Yes, let 64-bit rule!!!)

Change Threads:
Yes I can bring that back. But it can only have 2 modes: 1 thread, or threads >= cores (first power of 2 that's >= # of cores).
This is because of the way the program uses more threads than selected, so "extra cores" will skew results. There's no way I can enforce CPU affinity.

Efficiency Number:
Yes I can do that. But keep in mind that it won't scale across different sizes and # of cores.
Computing Pi isn't linear. It's roughly O( n*log(n)^3 ). So larger computations will have lower efficiency.
Also, the program doesn't quite scale linearly with the # of cores. So multi-threaded benchmarks will have lower efficiency.



Aside from that:

The next version, will use less memory. 1 billion digits will only require 5.25GB as opposed to 5.98GB of ram in the current release. Which means that it'll be possible for the "standard" Core i7 with 6GB of ram to bench 1 billion digits.

For the "very large" end, 10 billion digits will require 52.9 GB of ram (in the new version). By the looks of it, I "might" be able to squeeze that down to 46GB - which would make it possible for a fully-loaded 12-slot Gainestown server to do. And THAT would be interesting...

Anyways... Post your benchmarks everyone!!!

[moogle]

Anyways... Post your benchmarks everyone!!!

Nice to see a new Pi software finally made

[WhiteFireDragon]

how do you cheat in benching with superpi?

[poke349]

Updated the list of benchmarks with old results (from before the XS revert) and with results from other forums.


Stuff like tampering with the system clock, output tampering... is standard for cheating.

I've made sure none of that will work on y-cruncher.



Also, if everyone copy and pastes the validation text into your posts too. It would make it easier for me to validate.

[tet5uo]

Cool program!

Here's a quick test on my new rig.



It's core i7 @ 4.0gHz with 1600mHz DDR3 (QPI is only stock , oc'ed for 24/7 use with multiplier since It's a 965.)

[poke349]

Interesting... Your benchmark is valid (the checksum is good). But the CPU frequency is wrong... And by the very impressive timing, I can tell it really IS at 4GHz.

I swear there's something wrong with the rdtsc instruction... Because it doesn't detect turbo boost from 3.2 to 3.4 on my friend's computer. (it reports it at 3.2 even with turbo kicked on)

Maybe I'm not using it right.

Problem is: I actually don't know how to fix it. Anyone, by any random chance, know how to do this properly?

[tet5uo]

I'm awful at programming, so not much help here

Is there any way to get this data from the BIOS directly?

I noticed that alot of apps misread my CPU speed, the only thing that seems to get it right is CPU-Z or the EVGA version.

[poke349]

Okay, then I guess I'm not alone...

Would you mind if you try some of the smaller benchmarks?

At 4Ghz, you might be able to beat my dual-Harpertown rig at 25 and 50 mil.

Someone with a 920 OC'ed to 4.1 had a faster 25m and 50m time than my dual-Harpertown rig. But it's gone from the revert and it isn't in the Google cache, so I can't recover it.

[tet5uo]

Sure, I'll run a couple more tests and edit them into this for you.

Thanks for making this program I'm sure we all love to play with new benches

[spdycpu]

I did some runs at 4.1 (20x205) but I'm messing around now at 21x200 w/ turbo mode. As mentioned before it doesn't seem to detect that I'm running at 4.2GHz. I tried 21x205 for 4.3GHz but unfortunately my 2lbs of ice magically disappeared after about 2 seconds. I only managed a single run of 25m:

4.3GHz @ 21x205

Processor(s):   Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
CPU Frequency:  4,105,000,554 Hz
Thread(s):      8
Digits:         25,000,000
Total Time:     9.56572 seconds
Checksum:       3c277379f4ec9d5316e5b430710d0cbf

Interestingly enough 4.2GHz is stable in Prime95 and Linx, 4.3 just gives me fits however. 4.1GHz seems to run slightly faster in y-cruncher than 4.2GHz, I'd imagine due to the faster L3 and memory. More ice (MUCH more) is in the freezer, I'll try some 4.3GHz runs at 50, 100, 250 tomorrow.

Okay, then I guess I'm not alone...

Awesomeness... I'll be looking forward to those...

Finally I can kick myself off the top spot for one of the sizes.

I expect to hold the top spot only for the larger sizes... simply because no (overclockable) machine has the memory for it...

I'd love to see someone with dual W5580s and 72GB of ram show up and clean sweep these benchmarks...

Yes, I'll need to put the single-thread mode back in. Otherwise, y-cruncher is going to turn into a who-has-the-most-money server competition... (especially so with the ram requirement)
I don't exactly want to see the top spots being dominated by quad socket Dunningtons of some sort or whatever the new one coming out is... (As is the wprime benchmarks on hwbot...)

Oh wait, use the newest version, v0.3.1.

It has a benchmark mode fully equipped with my "lame" attempt at validation.

Also see if you guys can cheat the times too... I'm no expert in cheating benchmarks so I wouldn't know how to write a decent anti-cheat protection.

[Movieman]

Here's 25M and 50M with the latest version of the app:

[poke349]

Updated Your 25m re-run is slower probably because of normal variation. +/- .1 seconds is very typical for so many threads. (I see it myself on my Harpertowns...)

You should try some of the larger sizes... The program doesn't scale well with multi-threading for small computations.

You'll need to super-size it to at least 250 million before it can bring out the power of those 16-virtual cores.
