Hi,

With the new Mac Pro being announced at WWDC 2019 and SideFx endorsing it on the Apple webpage, the question arises as to the type of support that is being developed for it? i.e. Blackmagic Design, Otoy, Unity, Redshift/Maxon, Pixar and others have stated they are actively supporting Metal development.

I'm interested if the Radeon Pro Vega II Duo is fully supported as a compute card, and, if the viewport will be better supported than OpenGL 4.1.

Thanks!

The Duo's 2 GPUs can be used to divide the viewport and compute workload. One GPU can do all the rendering work, and the other can do all the compute work.

Houdini still uses OpenGL and OpenCL for those workloads. Apple still supports those for us, regardless of the deprecation of both.

Great! Thanks for clarifying. This helps enormously.

If future versions of Houdini change this, please let us know!

Thanks for the info! Does a duo card give any benefit compared to two regular GPUS on two separate cards? Like for example two Radeon VII cards ? If memory could be pooled I can see a benefit for larger simulations that uses OpenCL, otherwise, what is the point?

I believe the Duo is simply 2 separate GPUs in one package, each with their own VRAM pools. It only takes up one slot and might be somewhat more power efficient.

What twod said. We didn't add the Duo to the list of supported cards because we didn't want to give people the impression that Houdini would treat it any differently than two cards.
