Bifrost Benchmark

[morteza.cg]

woudn't it be cool to know how different processors perform with bifrost?!

it can help us build better pc and workstations for bifrost simulations.

I have never created a benchmark before so it may not be that good but i hope that even in it's current state it come in handy.

currently it's only for Aero, let's check it and if it was working as expected i will add mpm and instancing as well.

when you open the scene file you will see this window.

• at the very top you have two check box one for pausing viewport, it can help you if you don't have a powerful gpu. it's checked by default.

when you run any of the aero sims it will write a text file for you with your spec and simulation time

• if the second checkbox is enable it will remove that result file and create a new file for you everytime you run the simulaton and if you leave it off it will keep adding to same file.

after that we have 3 button each one will run a simulation.

• Explosion: a combustion test for an explosion like simulaton, it will run for 30 frame but source is only active for first 5 frame.
• Smoke: a basic smoke with collision, simulation will run for 100 frame
• rolling flame: a continous combustion simulation, it will run for 30 frame

after you run each simulation it will show the simulation time in the fields on the right.

Moderator's note: Removed the scene due to it containing the scriptJob described here. Please use the security tools for Maya. An updated version has been posted in the thread below.

3990x is really a powerful processor.

I updated the scene and added the "has property" node for all 3 graphs.

the benchmark window should open as soon as you open the scene but if you should be careful not to save over the file or it will no longer contain my script and the window won't show up.

I also attached a mel file to manually open the benchmark window just make sure the scene is also open or the mel file won't do anything by itself.

I added those 3 nodes manually. Strange thing is that , while opening your scene few times..... I did see once those 3 nodes and the value  of 0 7000 an 0 30.... I do not know what they do but simulation did work. The result of smoke dropped down 20%.

thanks for update

I'll test this updated scene out now. There is a bug somewhere I think. My 3990X has SMT on, so your UI ought to have reported 128 cores/threads, it only shows 64. Maybe that's an issue with the hardware command? @morteza.cg

Hey, guys I tested it on the latest AMD CPUs.
3995WX and 5950X
Interestingly As for the smoke test, the 5950X gave faster results no matter how many times I tested it.

[morteza.cg]

Amazing results! Thanks for sharing.

result from an i9 11900K

tested the benchmark again today with maya 2023 and bifrost 2.5. it seems like "has property" node doesn't work the way it used to.

at first it didn't even run the simulations.  i had to connect the simulation directly to the output and then disconnect it and only left the has property node and then it would run!

Hi Morteza,

Thanks for reporting the issue with "has_property". Unfortunately we're not able to reproduce. It seems to work fine on our side. If you find an easy-to-repro case, please let us know.

Cheers,

Michael

bo hoo i cant get it to run on my mac studio ultra.  

[michael_nielsen]

Hi Thomas,

Does Morteza's workaround above (https://forums.autodesk.com/t5/bifrost-forum/bifrost-benchmark/m-p/11540505/highlight/true#M7456) make it work?

If not, which version of Maya/Bifrost are you using?

Cheers,

Michael

[thomaslisle1309]

Hi

bifrost 2.5.1.0

Maya 2023.2

the primitives don't show up. - I replaced them with new ones and replaced the areo system nothing comes out on 

using the project has_property""

unlinking that also makes no difference.  

any ideas 

cheers thomas   the new mac studio ultra is very fast (20 cores. )but we may never know how fast with bifrost ! 

[michael_nielsen]

Hi Thomas,

Sorry, I missed this is related to the M1 chip. Unfortunately, there are no released versions of Bifrost that support M1 at the moment.

Cheers,

Michael

[thomaslisle1309]

Hi Michael

but Bifrost works fine on the M1 - except for this benchmark - what do you mean ?

cheers

Thomas  

[thomaslisle1309]

I have been using Bifrost on M1 chip  every day for nearly 5 months with no issues whatsoever  

[michael_nielsen]

Hi Thomas,

Sorry for the confusion my reply caused.

What I meant was that Bifrost does not natively support Apple Silicon (including M1), and at the time of writing I thought that might explain your issues. But since you're able to run Bifrost and it runs smoothly in all other cases I assume you're using the translation layer, Rosetta 2.

We will have a look at the scene file with similar hardware and software versions to see if we can reproduce the issue.

Cheers,

Michael

[thomaslisle1309]

hey great. well even in rosetta its 10x faster like everything is than my old puter. Now you mention it when are you going to port to apple silicon - its been nearly 2 years since the first silicon macs and im already planning to get a m2 ultra when they come out which i think will be faster than any pc on the market but who knows- definitely for the price point with a m1 ultra wins also on energy consumption . would be good to see a rosetta and then a native  benchmark. all the best thomas

[michael_nielsen]

Exciting to hear about the great performance. I agree it will be interesting to see native vs Rosetta performance. We're not allowed to discuss release dates, but I can say that we're working on native support.

Cheers,

Michael

[michael_nielsen]

@thomaslisle1309 FYI, another developer tested out the benchmarks on M1 with Rosetta but unfortunately was unable to reproduce the issues you're seeing. If you gain further insight into why it might be failing or a workaround, please let us know.

Cheers,

Michael

[thomaslisle1309]

hi its a shame no one in arnold or maya support seems to have a silicon mac, odd.  I'm really up to my eye balls in stuff to do, its not really a priority, great to hear someone got it working, maybe I'm missing something - could very easily happen! 

cheers Thomas
