Dan, you say that SIMD.js delivers performance portability, and Nadav says it
doesn’t.
Nadav’s argument seems to come down to (as I understand it):
- The set of vector operations supported on different CPU architectures varies
widely.
- "Executing vector intrinsics on processors that don’t sup
We will probably bring it up on es-discuss once we’ve had a chance to discuss
it among WebKit folks.

You are free to start such a discussion on es-discuss. I think it's useful for
the webkit community to be able to discuss what we think of the feature.

Hi Nadav,
I agree with much of your assessment of the the proposed SIMD.js API.
However, I don't believe it's unsuitability for some problems
invalidates it for solving other very important problems, which it is
well suited for. Performance portability is actually one of SIMD.js'
biggest strengths
Thanks for sharing your analysis on webkit-dev.
There has been a lot of criticisms about SIMD.js this year. It is great
to read about solutions for vectorization without the problems of SIMD.js.
