Default Opencl big-bang(Nbody) benchmark for multi device systems(heterogeneous or not) - 06-10-2013, 15:05 | posts: 67 | Location: Turkey

Hi, heres a benchmark for all of you benchmarkers. Needs java and opencl drivers installed.
New version! vector-type(vliw,mmx,avx) workload resolution increased.

Benchmark in Rar file(English): http://www.fileswap.com/dl/zaZqomw3bk/

If WINDOWS.BAT does not work, here is alternative:
http://www.fileswap.com/dl/h69qAKCfd7/
Benchmark with alternative batch file(English): http://www.fileswap.com/dl/qJiBMxfYzw/



Youtube video shows usage: http://www.youtube.com/watch?v=YNj10f-7yTA

When you dont have java: http://java.com/en/download/index.jsp

Drivers:

INTEL(HD3000 has problems, HD4000 working, no problem for CPU part, Xeon-Phi included)
http://software.intel.com/en-us/vcso...ols/opencl-sdk


AMD(AMD APP SDK) may or may not be needed
http://developer.amd.com/tools-and-s...sdk/downloads/

NVIDIA opencl
http://www.nvidia.com/Download/index.aspx?lang=en-us
https://developer.nvidia.com/cuda-toolkit-31-downloads


Just extract archive to a folder. Then run the WINDOWS.BAT or LINUX.SH to run the benchmark. If those dont work, just double click the jar file to run in that extraction folder. If you have MacOSX or Solaris, just run the .jar file.

This benchmark is written on Java using (jocl) + (jmonkey engine 3.0) by me. This program uses opencl power to simulate a big-bang of 25600, 51200, 102400 particles just like a super-nova (without relativistic approach) on any opencl-capable device(or combination of devices) to get benchmark points related to cumpute performance(linearly dependant to gflops value but exponentially dependant to particle number because this is full O(N^2) ). For example, if you get 1000 points in 51200 particle test, you will likely get 250 points in 102400 particle test. Ofcourse gpu will be better performing with more particles so you will get 300 instead of 250. 25600 particle test is easiest and is related with host(cpu), device (cpu-gpu-accelerator-coprocessor) and ram performances.

VLIW4(and 5), SSE, AVX, GCN, CUDA, float16(Xeon-phi) capability included.

Opencl is slower than CUDA for same Nvidia hardware, so Nvidia scores will be multiplied by 1.2 to have an idea about how CUDA performance would be.
Old but the only source I could find for this multiplier: http://arxiv.org/ftp/arxiv/papers/1005/1005.2581.pdf




Theres scaling for at least 4 cards or even heterogeneous device combinations like nvidia+amd+intel's HD4000.

I will add any scores with screenshots of score results and cpu-z gpu-z.
Warning: this will heat like prime95 or furmark in the process. Dont use a low gflops cpu with a high gflops GPU because GPU will mostly be idle waiting for CPU periodically plus increasing(and suddenly decreasing) temperature on itself(if you do this, you will need a solder-gun, GTX700 series may be immune to this because they have temperature-lock mechanism, I dont know)
Absolutely no harm for similar-performance heterogeneous devices. Example: HD7850+GTX660 or 2*Xeons and a HD4830

For two or more devices used, you can use any workload ratio such as 50-50(crossfire or two), 30-35-35(triple sli but first card is doing the video output work so decreased opencl load), 25-25-25-25(4*opteron)

Some scores from another forum for 25600 particles:
GT650M (1000/1500) ----->1371 points (i7 3610QM 3.1GHz)
Intel-HD4000 (1100/800) ----->482 points (i7 3610QM 3.1GHz)
Xeon-E3-1270-V2 (3500MHz-7 threads) ----->268 points
i7-3770K (4500MHz-7 threads) ----->207 points (igpu off)
FX8150 (4300MHz-7 threads) ----->142 points
Full list: http://forum.donanimhaber.com/m_75692871/tm.htm

Important note: If you use your CPU for benchmarking, you can change the number of cores used for computing and used for data-moving/rendering from the scrollbar under benchmark buttons(slider to left for max cores computing, slider to right for minimum cores for computing)



Thanks.

Dont mind below:

High performance computing, benchmark, OpenCL scaling, jmonkey engine 3.0, jocl, galaxy simulation, nbody benchmark. Xeon-phi, Titan, multi-thread. Rise against injustice. Megadeth.

Can OpenCL 1.0 driver work this bench?
OCL 1.0 is ~1.5x faster than 1.1 (abnormal performance for NVIDIA card only).

@ricardonuno1980: I used simple vector-driven kernel and very basic cl-methods which must be avaliable for all opencl versions. This package uses jocl's opencl 1.2 compatible version. But works with 1.1. Did not try for 1.0.

@yasamoka: waiting for 2x7970.

@---TK---: Nice, I will multiply your score since it is Nvidia (as a rule for this benchmark, to get an idea "how would this be in CUDA?") Adding your score(this is 25600 I suppose)

Actually, program uses your computer's opencl drivers. Program has 1.2 capable jocl module but uses simplest methods even for 1.0 version. Maybe device-fission for cpu can be paint. GPU should be okay. You can try, if you have any corrupted opencl dlls it could give errors.

Please dont forget to put your ram frequencies for the first test. ***304;mportant beause you may get low results with slow memory. WINDOWS.BAT gives 2GB ram to java virtual machine. With just running .jar file, you are without that memory area hence being slow.

Ok.

GTX 480 (320.14Beta) got 2168 pts at 25600 running Win 7 x64 SP1 with CPU i5-2500K@4.5GHz.

@---TK---: a titan from another forum got 8518 points at 1140MHz and this makes your sli challenging even with this light-load test.

@ricardonuno1980: your score makes sense since HD5850 gets similar scores with you in another forum. Dont worry. Adding to list.

Yes thanks, actually what I did was only connecting jocl with jmonkey engine and doing all in an self-runnable applet within a jar. It was hardwork. Without jmonkey and jocl, it could be harder than hard.

This benchmark will become a collision of two planets with shiny surfaces and breaking into asteroids then forming a big planet.

What's the point of a benchmark if you are going to multiply the Nvidia CUDA scores by 1.2x because they are lower?

Because the point of Nvidia is CUDA which enables a more low-level hardware features making somewhat faster. Originated from: http://arxiv.org/ftp/arxiv/papers/1005/1005.2581.pdf here you can see that the performance ratio of a Nvidia card for CUDA/Opencl approaches 1.2 multiplier when you increase total-work-thread number(making a heavier load).

Note: I am HD7870 + FX8150 user, not a fanboy and absolutely not a Nvidia fan. Maybe a CUDA+Opencl experienced programmer can tell me if I am wrong. HD7870(pitcairn) easily passes GTX660-TI in opencl. In CUDA GTX benefits. If you have CUDA then one can say "whats the point of using opencl?". To counter that, just multipled by 1.2 according to an old but only clue I found the pdf file above.

Cool benchmark!

Unfortunately I cannot submit a score because the program always locked up on me before it finished.

Do you see exploding particles all around? Does it draw anything red? What are the temperatures? Your driver version? Was the driver update properly done? Too much overclock?


Unfortunately my timezone tells that I need to sleep.
When I wake up, will refresh scores table. Good night.

Yeah, it starts working fine, I can see the big bang and the particles start lumping around via gravity, can move and zoom in/out, etc.

Temps are great, I'm on the 320.18 drivers.

OC's are rock-solid and I tried running it at stock, still locked up.

Always seems to lock up with ~10 seconds or so left.

Try changing the WINDOWS.BAT 's including commands such as changing 2048M to 4096M to give it more ram. I am going sleeping im sorry . Will solve this issue when i wake up.
I have some friends that worked titans and sli titans. Temperature go beyond 90C ?

Single card works?

Opencl is not rock-solid always because can put weight more that anything.
If we are really desperate, we can extrapolate your scores for the 50-seconds.

Changed it to 4096, still locked up.

Maybe you can get it sorted for me tomorrow.

What happens when you replace windows.bat 's command with this:

java -mx2048M -jar kutleCekimi.jar

Can you try with single card? If it doesnt run properly, there must be a driver issue.

Can you enter "java -mx2048M -jar kutleCekimi.jar" in cmd console while in the folder?(without "")

@TwoPlusTwo: When it stucks at 10seconds left, what do you see on command-line console? Does it give any errors? (you must use windows.bat to see that ofcourse)

New version out:

*increased workload resolution for vector-type architectures.

*if somehow a corrupt graphics driver sees a gpu as vector-type rather than scalar-type, this may have been solved.

Please check new rar link in first post.

Can you enter "java -mx2048M -jar kutleCekimi.jar" in cmd console while in the folder?(without "")
Changing WINDOWS.bat to say that doesn't help, neither does trying it with a single card.

When I try running it from the command prompt I get an error that says something like "command "java" not found" even though I do have java installed.

My drivers are 320.18 if that helps.

Last time I ran it, I get 9665 points when it froze up at 9 seconds. That's the closest I'll get to posting a score here. :p
