  1. 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
  2. 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.
  3. 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.
  4. 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.
  5. 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!
  6. 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.
  7. 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
  8. 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
  9. 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.
  10. 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.
  11. Ubuntu partitioning issue

    I would try the Ubuntu forums since the issue doesn't involve Houdini at all. https://ubuntuforums.org/
  12. 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.
  13. 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.
  14. 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.
  15. 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.
