I saw some mention of Linux ARM at the end of the video. With the release of NVIDIA Spark, it looks like there's a perfect platform for Karma XPU to run on. Is there anything can share?

Hi chongsong, yes! As mentioned in the keynote, Houdini 22 will ship with a Linux ARM build. Just like our original Apple silicon port, it will be designated as a "Technology Preview" as we address feedback from our users and make sure that it's ready for prime-time.

We've tested Houdini on the following platforms so far:

• AWS Graviton
  
• Ampere Altra/Altra Max
  
• NVIDIA DGX Spark
  

The build targets the Neoverse-n1 instruction set. This corresponds to a minimum of AWS Graviton2 and Ampere Altra. Unfortunately this means that you most likely won't be able to run Houdini on low-end SBCs. You can see if your CPU supports all of the features of neoverse-n1 here [gpages.juszkiewicz.com.pl]

The only other caveat to this build is that there's currently no support for FBX as it isn't available for the platform yet.

This build features not only the command-line utilities, but the entire interactive interface as well, meaning that it's fully supported on Arm workstations from the likes of Nvidia, Ampere and System76.
