Does vfxplatform take a position on 32 bit builds?

[Nick Porcino]

Does vfxplatform take a position on 32 bit builds? On the OTIO project we are discussing whether we should be building 32 bit wheels for the community, and one thought was to follow the lead of the vfxplatform, if a precedent or decision exists on that topic. We do have a specific distribution for ARM that needs to be 32 bit, but we're wondering about Intel in particular.

Does anyone have advice?

The VFX Ref Platform does not take any particular position on 32-bit builds at this time. If anyone thinks it should then we'd love to hear about it.

Thanks,

While I can't speak for everyone, my observation has been that vfx jumped onto 64-bit fairly early in the game because of the size of the datasets involved. Exactly 14 years ago in our case. The DCC apps I know no longer provide 32-bit support and have not for a while.

I'm going to officially wish that 64 bit is expected and 32 bit is not-expected-but-allowable, because it will ease decision making where support determinations must be conservative, and where it is impossible to precisely determine who might still be on 32 bits.

It has never been the case that something not on the list is "disallowed."

It just says which library versions to use if you want to minimize potential compatibility problems with the major DCC apps each year.

Yes. Previously we've determined that the vfxplatform only covers versioning where different versions significantly impact the ability of the components of a pipeline to play well together; by that criteria 32 vs 64 bit builds don't need to be called out. vfx-platform does have the word platform in it though, so I think it never hurts to ask or examine what we might like to take a position on. I'm going to recommend that OTIO doesn't take on 32 bit python wheel builds, as that choice is not in contradiction to the vfx-platform spec.
