  1. Is AMD potentially risky? (Threadripper)

    Speed performance seems totally reasonable with OCL and if i can bypass the RAM capacity with your suggestion that's a sure win! I'm eager to try out a cloth grain based sim knowing this now... And I wonder if I can apply the same process for a larger Pyro sim with OCL... I'll make sure to send the results to SideFX, Thanks Marty
  2. Is AMD potentially risky? (Threadripper)

    I think i ran most tests 2 times but yeah, OCL on GPU seems to improve Grain results immensly, a good question would be how much gpu RAM is neccessary for your average type grain sim situation. If you wish to make another type of grain Sim i can run it... PS: On this particular station i am running 4x GTX 1080, but is OCL using all cards or only one? @marty any info about this? Judging by ram usage during the sim, it is just 1 card... the ram usage went up 30% during this sim, so that would be aprox 2.4 gb V-ram for 700k points

    Hi, didn't get to it but i'm pretty certain it's a short matter of time before we see support for both of them...
  4. Is AMD potentially risky? (Threadripper)

    Thank you! updated the scores spreadsheet...

    cool guys, thanks. Regards,
  6. Is AMD potentially risky? (Threadripper)

    I got open CL for CPU to turn on at the office of a studio i work for, on the i7 6950x, was indeed as simple as setting the ENV file, this would not work at home on the 7900x. i'll try to run the grain benchmark from VFX ARABIA, all i have to do with oCL set for CPU, is turn on all the OCL ticks inside the DOP network, correct? here are the numbers for the Grains scene from VFX Arabia, res 0.01: No oCL -12:16 CPU oCL -08:04 40% faster than no OCL GPU oCL -06:15 63.7% faster than no OCL (gtx 1080)
  7. Is AMD potentially risky? (Threadripper)

    Yup we are moving closer and closer to proper multi-threadding support for sure! Just was not convinced if it is right around the corner or not so I personally made a bit of a trade-off for now
  8. Is AMD potentially risky? (Threadripper)

    Sure no problem, will post the results, i'll run it a couple of times to see if the numbers stay consistent. One mention though: i will not let it go to the mantra rendering. Can't keep my workstation unavailable for a few days at a moment and we already have cinebench scores and some mantra tests. Speaking as a freelancer,and especially from this position, CPU rendering is not an option for me, i would not want the hassle of online renderfarms and i am trying to keep my setup compact, hence one workstation for all things, from modeling texturing to rendering to comp. I could not afford to leave freelance jobs to render for on CPU on a single computer this is why Redshift is highly preferable for me. This is my current production environment. I did work in a facility where i had to take care of a 30 PC vray render farm (running on backburner) and i am glad those days are over for the types of jobs i like to work on. So i will only post the numbers up untill the Mantra tasks for now. As a personal opinion/conclusion to the other tests we had on this thread, as i previously stated it is more important to decide what are your personal needs, for an effects TD i would say TR is a win no question. Again speaking as a generalist freelancer the jobs i do are varried and i cannot guarantee i'll do Pyro all year or flip or even heay sim stuff. Still it is comforting to see lower res sims go fast on the intel, so this means faster RnD with the expense of leaving it to compute more for the final rez sim once and when I get there. I'm really interested for any more under the hood or behind the scenes info you have about this stuff and those SOPs setups you mention sound interesting, so far i've fund this thread very educating and it is good to find out more about how Houdini works. Also the benchmark scene you posted is really interesting to learn from especially the deadline management of the rops, so i am grateful for that!
  9. Is AMD potentially risky? (Threadripper)

    Deadline is great and i never used it like this - but i am running the test right now, i am not entirely sure this is such a universal benchmark. my I9 has finished chewing on all the sim-based tasks, with the only ones left being 3 mantra ones (wich supposedly will take a few days to render?) so again it looks to me like it is is a mostly CPU rendering test. Still no grain, liquid (with proper meshing setup), complex sops opperations with no simming involved, or FEM. So i am preparing a FEM benchmark next...
  10. Is AMD potentially risky? (Threadripper)

    yes this was supposed to be a more single threadded collection of use cases (i'm sure the methodology can be improved), i'll update the running spreadsheet. Thank you for running the test! in related news, mr Timucin Ozger, lead FX TD for MPC, has kindly provided a through benchmarking scene file with the bonus of having a Deadline implementation: Link to the SideFX forums post: https://www.sidefx.com/forum/topic/51730/
  11. Is AMD potentially risky? (Threadripper)

    Yes, at 4.8 it was actually asking for more current than i was giving it for it to become stable under load. But more current would mean larger temps at 4.8ghz i was getting auto throttling from the CPU hardware fail-safe mechanisms. 8 cores at 4.7 and 2 at 4.6 runs indeed hot, but no throttling and no instability so far for renders or sims or any other of the benchmarks, and some of them run hotter(90+) some of them run cold (70+). PS: if you don't mind, and have the time, could you please try out my sops/Bullet benchmark on your machines? @Beatnutz still around for some more tests?
  12. Is AMD potentially risky? (Threadripper)

    Hi guys, i'm back with an update. I managed to dig up an older project and turn it into a benchmark scene. I've added more details on a note inside the project, in short it uses a few for each loops, attribute transfers, a sop solver inside a DOP network, an RBD solver over some packed geometry. The last run of SIM benchmarks sure do the extra cores justice, but Houdini is more than those 3 types of sims, i'm still curious to find out how it behaves in different circumstances. I've tuned my 7900x some more this weekend: the basic OC profile i ran from the BIOS was overvolting the CPU unnecessarily, hence larger temps on lower speed. I managed to get 8 of the cores running@ 4.7 and the other two@ 4.6( these two where slightly underperformers and got hotter than the others at the same speed), now so far in my particular case this is what i would call a stable and workable rig with the AIO and a good chasis with fans. the CPU is really an overclocking champ but the temperatures are the main issue. (Disclaimer, overclock only if you know what you are doing, don't take my word for it, please understand this still remains risky for any CPU, intel or AMD) So far i've run benchmarks of intense workload for just under the one hour mark. Now it is worth mentioning i did get to see it reach 4.8 ghz on all cores, it was stable enough for a few benchmarks but the system froze on mantra rendering tasks, this is getting into delidding teritory. i've added the new scores in the spreadsheet ( https://docs.google.com/spreadsheets/d/1jQFxPdOBcWbYtJJkVafr4VYojhkV5MqInZmEsT_zmZA) So all this speed got it closer to the OC threadripper for these kinds of sims with PYRO seein the TR a clear champion.(lots of multithread love going on in PYRO it seems, kudos!) Now back to my initial point, here is the link to my SOPs benchmark proposal. Of course i am open to opinions about it if it can be improved somehow or if there are better types of tasks that touch general use. https://drive.google.com/open?id=0B-EHM5diHgrERHAwanZCdXZON28 @DaJuice eager to see some scores from your TR for this also
  13. Is AMD potentially risky? (Threadripper)

    Wow gap really got wider this time. It's great to see some clear results about these two CPUs. Looks like i would need to push the i9 more than i thought. Added the TR results to my CPU benchmark as well. I'll try some OC tuning this weekend but already i'm considering returning the CPU and Mobo for a swap , there is more to take into account besides these 3 kinds of sims but i was aiming for their gap to be smaller than 33% with both OCed within their respective comfort zone @DaJuice Just to be clear, you used the perf monitor like this: hit record, go back to scene view, type in frame 400, then read out the time from the Performance Monitor displayed at "Total Statistics" ?
  14. Is AMD potentially risky? (Threadripper)

    No problem, yes, same configuration as the rest of the tests
  15. Is AMD potentially risky? (Threadripper)

    @DaJuice Actually i was getting longer times than the first run this time for the Bool sphere. No ideea why yet. To add to the mistery, today it's back udner 16 at 15:57. About the cooling. The fact that there were no waterblocks on AIO kits large enough to properly fit the TR format and i was a bit in a hurry also put me off to going that route. Of course one can only guess at this point how much or if it would make a difference but already you have options for this at least in custom land: https://www.ekwb.com/shop/ek-supremacy-evo-threadripper-edition-nickel EK waterblocks and gear is probably the way to go for a custom rig but i didn't want to jump into it yet myself. Will try their radiator fans at some point as they are very strong and could offer a noticeable boost on temp readings. Also worth noting this company was offering some AIO kits of great performance but they are not available now. I was reading they are preparing an improved version that will come out soon, so you might want to keep an eye out for that. If i feel more adventurous in the future and i absolutely want to get the most out of the intel I could consider to delid it, a bit extreme but it will unlock temps enough to go over 4.5ghz, was seeing a 7900x (with no delidding) reach 4.8 ghz but it was not stable enough for benchmarking. Sure i can do the Tabasco Mantra benchmark for statistic's sake but i can already bet TR will beat the 7900x in this department
  16. Is AMD potentially risky? (Threadripper)

    I have an upcomming freelance gig with lots of dust-smoke so i'll update my findings. From OC results for this AIO and the 7900x i'm pretty confident it's going to be stable though. I really weighed in as much info i could gather about how far i could take it realistically because at stock speed it's not up to par with an OC TR or else i would of just went with a TR and stick to OC ing it. Yup, i am sure you're tests are relevant. I'm all about leaving the necessary info to anyone else looking to do an upgrade. I know i wish i had less headaches about the final decision. Actually cancelled a TR order and the mobo for it at the last minute . Not really seeking to be right at this point because they both do a good job but i am interested to find out about the particulars, most online reviews don't actually deal with the needs of professional day to day use so we depend on each other to find out these things, just as learning more skill-wise. @VFXArabia managed to run through the tests, added the results to the spreadsheet, you can pick them up from there. also i used the testing method you specified:
  17. Is AMD potentially risky? (Threadripper)

    Hi guys, was away during the weekend. The cores individual temps cycle between 43 and 81 degrees celssius when running the bool sphere, the AIO has a fairly gressive fan curve now, going to 100% for the fans when temps go over 60-70 degrees. I'm also running a power blanced mode in windows that only pushes the cores to max clock when softwares demand it, the rest of the time they iddle at 1.2-1.8 ghz for max power and temp efficiency. I've read that i can change the fans that come with this AIO for some high end ones and that will boost the systems cooling capability, good to know if i really want to crank things up in the future. Odd thing is now that i ran the Bool test again i get a different score, 16:06. I ran it a couple of times(same with all the benchmarks) with the same result last time but now something is different. Ah well. Updated the spreadsheet accordingly. I'll be back with an update if i found out what's up. There's some effort still left for me to put in to get the best possible balance for temps and clock speed but right now it's stable and fine like this. Added your OC benchmark updates to the spreadsheet. How are your temps running? I understood from some OC articles that 4ghz is pretty much the most you can squeeze before temps and power draw start to get crazy. https://docs.google.com/spreadsheets/d/1jQFxPdOBcWbYtJJkVafr4VYojhkV5MqInZmEsT_zmZA @VFXArabia I'll try out your tests as soon as as possible
  18. Is AMD potentially risky? (Threadripper)

    sure is, but i'll try oCL again at a later date, could be teething issues. Thanks for your guidance in any case
  19. Is AMD potentially risky? (Threadripper)

    hgpuinfo -l is listing me my 2 graphics cards, no CPU though
  20. Is AMD potentially risky? (Threadripper)

    OpenCL Exception: Could not create OpenCL device of type (HOUDINI_OCL_DEVICETYPE): CPU on platform vendor (HOUDINI_OCL_VENDOR): Intel(R) Corporation. The built-in CPU driver may not support your CPU (-2) i get this error, am I doing something wrong?
  21. Is AMD potentially risky? (Threadripper)

    Sure i could do it. For this i need to just put HOUDINI_OCL_DEVICETYPE=CPU in the env file and turn on OpenCL on all the nodes that support it?(mainsolver and any microsolvers)
  22. Is AMD potentially risky? (Threadripper)

    Thanks, i've edited it!
  23. Is AMD potentially risky? (Threadripper)

    So here are the results for i9 7900x running all 10 cores @ 4.4ghz, RAM@3000mhz Grain 1:31 - 17.08% faster than TR [1:48] Pyro 6:03 - 7.6% faster than TR [6:32] Fluid 0:26 - 14.2% faster than TR [0:30] (TRscores from Beatnutz 1950x @ 3.8GHz, RAM @ 2133MHz) Boolean Sphere score: 15:43 01.05 % faster than TR 1950x (16 cores)(DaJuice's 1950x @ 3.75GHz, RAM @ 3200MHz) [15:53] 12.02 % faster than TR 1950x (16 cores)(Beatnutz 1950x @ 3.8GHz, RAM @ 2133MHz) [17:46 ] 25.26 % faster than Ryzen 1700 (8 cores) (Marty's score in performance mode Ryzen 1700 @3.68GHz) [20:20] Cinebench scoresMultithread:2371 28.65% slower than TR (Beatnutz 1950x @ 3.8GHz, RAM @ 2133MHz) Singlethread:188 30.67% faster than TR (Beatnutz 1950x @ 3.8GHz, RAM @ 2133MHz) Still not totally convinced about the fluid benchmark, it goes too fast for everyone, i think it needs more resolution and also meshing involved, it well may be that the test is so short that the CPU does not even get enough time to distribute the tasks to all resources. Not totally convinced about the Boolean sphere because it is a mostly CPU mantra rendering test. But i think the i9 does it's job well for what i needed it to, a general task performer in Houdini, excluding any CPU rendering needs. I'll see if i can dig up some intensive sop projects i did a short while ago, took an RBD sim of pieces blowing away, then used a for each loop to scale them to 0 and blast as they get older. 4.4 ghz on the i9 was kind of out of the box, did not change any settings manually in the BIOS yet, just turned on an XMP profile. I'm cooling it with a 360 AIO watercooling solution (closed loop, just install it and run it). Would be cool to see more scores from the 3200mhz RAM TR build (for the 3 sims benchmarks). i added the results from this thread to a spreadsheet it can be found here: https://docs.google.com/spreadsheets/d/1jQFxPdOBcWbYtJJkVafr4VYojhkV5MqInZmEsT_zmZA/edit?usp=sharing Please let me know if you noticed i missed anything or put the wrong numbers somewhere.
  24. Is AMD potentially risky? (Threadripper)

    Ok guys, got all the parts today and took me a few hours to assemble. Spoiler: 7900x still gets it's ass kicked in multithread cinebench: 2371 points (but i knew that before buying it) the rest of the benchmarks get more interesting. I'll post an update tomorrow...
