  1. X570 Aorus PRO - Ryzen 3900X memeory issues! Please help.

    That has nothing to do with the memory or stability. If anything you're better off with ECC memory which Intel doesn't support on consumer platforms but AMD does (including the Ryzen 3900X you already have). Intel doesn't have a magic wand to make sketchy memory more stable. I've had bad DDR4 memory module that memory tests never found an issue with. If you have more than one DIMM then I would try working with only one of them for a day, or half of them for a day, until you can narrow down which one is crashing. It could be the processor or motherboard but the memory modules are more likely candidates. If you end up needing to buy more memory out of warranty you might consider ECC memory this time around. While a bad DIMM is a bad DIMM that needs to be replaced at least you'd get warnings and logs of corrected memory errors instead of hard crashes.
  2. Pyro Render Passes

    Try increasing stochastic samples (by a lot).
  3. setting up Flip distributed Simulation on a single machine

    This. It can be faster if the synchronization between the slices doesn't take longer than the single threaded parts would take on their own. Doing this doesn't turn 64GB of RAM into 512GB of RAM. All of the slices still need to be running concurrently so they can be synchronized after each timestep. If anything it would use even more RAM running a distributed simulation on one machine compared to a single simulation. Here's some cool reading if this stuff is interesting to you. https://en.wikipedia.org/wiki/Amdahl's_law
  4. There's an option on the Table Import node to convert latitude and longitude to position on a sphere. Table Import (sidefx.com) The math can be done elsewhere if you want but that node makes it pretty easy.
  5. How do I check my account number?

    Login at their website, click on your profile in the top right, services, manage your licenses. It'll be on the top right.
  6. You should use the render in background button on the ROP. The percentage for a single frame will show up in the render scheduler dialog (which it should prompt to open when creating a background task). The scheduler is also available from the render menu at the top.
  7. Houdini Lover seeking for job in Texas

    The team I work with is looking for a compositor and Houdini experience is a plus. It's a small team and our primary 3D application is Houdini. The position requires US citizenship. Multimedia Design Engineer (Grand Prairie, Texas) at Lockheed Martin Corporation (lockheedmartinjobs.com) If it's a good fit check it out. If not, I hope your search goes good. There's a lot of great places in Texas!
  8. Lockheed Martin in Suffolk, VA

    The team I work with is looking to add someone to the team in Suffolk, VA. We use Houdini as our primary 3D application along with a mix of other stuff. It's a generalist type position with opportunities to grow in areas of interest to the candidate. I'm not the hiring manager but I'm happy to answer questions. The job listing is linked below. https://www.lockheedmartinjobs.com/job/suffolk/engineering-visualization-engineer-3d-generalist/694/9209867248 This is the facility where the new team member would be working. The job would be on site. There's team members at a few locations that work together on projects. https://www.lockheedmartin.com/en-us/capabilities/research-labs/center-for-innovation.html This video is representative of the kind of work the team does. We tell engineering stories like how something works, how something is made, how something is different, etc. Unfortunately most of the work isn't public, hence the pretty old video link, but what we're doing is pretty cool stuff! https://www.youtube.com/watch?v=h449oIjg2kY We might have another video that we can share with the public soon. If that's the case I'll share it here when it's online.
  9. not full CPU power during simulation

    It's likely that some of the code can't be executed in parallel. Lots of things will affect this in Houdini like the type of objects, size, and complexity of the simulations. In theory you want a single core CPU with unlimited frequency. In reality it's not that simple. https://en.wikipedia.org/wiki/Amdahl's_law
  10. Arch Linux

    Arch will occasionally break. I personally wouldn't use Arch for VFX and animation production. The benefits of Arch aren't relevant to production. Those are from their wiki. https://wiki.archlinux.org/index.php/System_maintenance#Upgrading_the_system
  11. Why is it so hard to get help on larger scale FLIP sims?

    It would be easier/faster/cheaper to get more computers to distribute the workload or get one computer that's better. I realize money isn't infinite but neither is time to kludge stuff. You can get a used workstation with 24 cores and 256 GB of memory for less than $2,000. https://www.theserverstore.com/dell-precision-t7810.html A machine like that would be plenty of power to learn with and create some impressive demo material. There are lots of other options but my point is to address the hardware problem if there's a hardware problem rather than looking for other less efficient ways to solve the problem.
  12. Why is it so hard to get help on larger scale FLIP sims?

    Looking at your previous posts, I would say it's your questions rather than the topics that are leading to no replies. In my opinion your time would be best spent on tutorials and checking out the documentation to get a better handle on the fundamentals of Houdini. That would enable you to ask better questions that would be more helpful to you and more efficient use of time for everyone else. In general I wouldn't start the process of learning Houdini via complex topics like FLIP simulations and dynamics. https://www.sidefx.com/learn/getting_started/ Master the basics and then everything else will be much easier. The beginner stuff might seem boring but it's essential to understanding the more complex topics.
  13. Ubuntu partitioning issue

    I would try the Ubuntu forums since the issue doesn't involve Houdini at all. https://ubuntuforums.org/
  14. Best Linux district for Houdini VFX

    If you're using Maya then you're limited to RHEL 7 or CentOS 7 for now. They're not great... https://knowledge.autodesk.com/support/maya/learn-explore/caas/sfdcarticles/sfdcarticles/System-requirements-for-Autodesk-Maya-2020.html There are ways to install it on other distributions but if you're new to Linux, I don't recommend going down that road as an introduction to Linux. If you drop Maya from that list then you have a lot more options like Ubuntu and any Ubuntu derivatives like Linux Mint. I would go with Ubuntu 18.04 LTS or 20.04 LTS assuming there's no Maya.
  15. Houdini Mac user population

    I started out my computing days with Mac OS 6 if I recall correctly. Had various Mac computers at home up until the G4. At work I used Mac in various places up to an including the garbage can which was a joke of a workstation. I haven't used Houdini on a Mac since the cheese grater days (circa 2012). Given the choice today I'd go with a Windows (or dual boot with Linux) workstation over a Mac. Any Mac option simply isn't cost effective for 3D work anymore. They were somewhat in the cheese grater days but definitely not today.
  16. Studio Workstation

    Boooooooo, get off the stage. High end air coolers are just as good (some are actually better) and when they fail there's no collateral damage.
  17. Houdini Pyro Division Size parameter animation

    You could resample an existing cache like that but I think it would be a lot of work (probably not worthwhile) to simulate something in that fashion.
  18. Mac Pro with limited funds

    It's not my fault Apple doesn't sell parts to build one. That doesn't mean the rest of us have to pay through the nose though. Me too. Since System Software 6 to macOS. I've been burned enough times by Apple to know better at this point. I can see the secondary uses and lighter duty processing but as a primary 3D workstation? Pass.
  19. Mac Pro with limited funds

    If you must use a Mac then I'd get the base model and upgrade the CPU and memory. If you're not comfortable with upgrading the CPU then I would buy that from Apple. The memory and GPU upgrade prices from Apple are a joke. You might consider buying something like a Mac Mini for macOS specific tasks and then building or buying another machine. It would be faster than a Mac Pro for 3D work and still cheaper after buying two separate machines. The longer you do 3D work on Apple the more your work will suffer. If you can do more iterations in the same amount of time then your work will improve faster. It's not about this platform or that platform is better. It's about optimizing your time and improving your work. Better hardware is essential for that. Don't kid yourself into thinking the raw performance isn't a big factor because it is. https://www.wiredzone.com/shop/product/41110244-supermicro-sys-7049a-t-tower-barebone-dual-processor-7056?search=7049A-T+ https://www.wiredzone.com/shop/product/10030030-intel-cd8069504213901-xeon-silver-4216-2-10ghz-16-core-processor-gen-2-4033?search=xeon+silver+42 https://www.wiredzone.com/shop/product/41110434-supermicro-mem-dr432l-cl01-er26-memory-32gb-ddr4-2666mhz-rdimm-3299?search=supermicro+32gb+ecc+ddr4 https://www.wiredzone.com/shop/product/41113212-samsung-mz-v7e2t0bw-hard-drive-ssd-2tb-pcie-3-0-nvme-m-2-970-evo-2075 https://www.wiredzone.com/shop/product/10030198-seagate-st16000nm001g-hard-drive-16tb-sata-6gb-s-7-2k-rpm-3-5in-2471?search=16tb https://www.nvidia.com/en-us/geforce/graphics-cards/rtx-2080-super/ Food for thought. That's a build for a machine with 32 cores (64 threads) at 2.1GHz with 3.2GHz turbo, 512GB of ECC memory, 2TB NVMe SSD, 64TB of HDD storage, and a Nvidia RTX 2080 Super. It would be under $9K including Windows or you could throw Linux on there. It's faster and better than the Mac Pro in every way by a long shot. If you didn't want the HDD storage you could get two video cards, or add more memory, or upgrade the processors.
  20. Mac Pro with limited funds

    The 2019 Mac Pro is an utterly terrible computer for 3D workflows no matter how you spin it. As was the 2013 Mac Pro. Apple hasn't had a serious contender in the workstation market for over a decade. You can do your own research but this video sums it up pretty well.
  21. Run Python script after Houdini starts

    You could have a script that launches RPC and then do whatever via RPC. Depending on what you're trying to do this might be overkill/cumbersome. https://www.sidefx.com/docs/houdini/hom/rpc.html
  22. Hqueue Configuration with NAS nightmare

    Last time I used HQueue years ago it was a hot mess. I'm sure you could get it working but I'm not sure it's worth the effort. If you have only 2 clients you might try Deadline. It's free for up to 2 clients. After that it's $48 per client per year.
  23. Best Linux Distribution for Houdini ?

    That's not why people use Linux. As an individual user there are few benefits like more privacy, more control, and less bloat-ware. For a studio there are many benefits related to scalability and flexibility that Windows either can't do or does terribly at like... Hugely scalable and high performance parallel file systems like Lustre and Gluster Powerful configuration management tools like Salt, Puppet, Chef, and Ansible Integrated support for enterprise hardware like high speed network adapters and disk controllers No silly artificial hardware limitations on the number of processor sockets or quantity of memory Full control over any aspect of the operating system like automatic updates and desktop interfaces Ability to automate just about anything that happens on the machine I'm not saying people shouldn't run Linux as an individual. There are lots of good reasons to run Linux as an individual. Just saying that it's not faster.
  24. Fedora vs. Centos

    Fedora will have more modern features. CentOS will have many years of support and more stable but older features. If you don't want to be updating your operating system every six months then use CentOS. If you don't mind the tinkering every six months and want the latest features then use Fedora. Why does RPM matter? Autodesk software? If that's the case then CentOS 7 will be your only option for now. Maya 2020 which just came out doesn't support CentOS 8 and they dropped support for Fedora entirely. I'm amazed that people still use Maya.
  25. Limit total smoke

    Key the scale on the source from whatever down to zero.
