[blog] Early Performance Findings: Babylon/HAT and TornadoVM

[Gary Frost]

Thanks for the link Juan.

This is a nice writeup, and I think offers a pretty succinct view of the current state of play.

Whilst I believe it is pretty early for us to chase perf comparisons, I think this puts a nice stake in the ground as we prepare to implement our algorithm for automatically avoiding unnecessary buffer transfers.

Re 2D and 3D ranges and for mechanism to select specific GPU's.  These are all in the 'backlog' :) thanks for keeping us honest.

I look forward to continued HAT + TornadoVM collaboration in the future.  I think the iface-mapper is very likely to be an early collaboration point.

Gary

Subject: [blog] Early Performance Findings: Babylon/HAT and TornadoVM

Hi all,
    I've written an article comparing some performance of Babylon/HAT against TornadoVM. Since this touches on GPU utilization and performance, I thought it might be of interest to the GPU folks here. The article also includes some constructive feedback on both technologies.
You can find the article here: https://jjfumero.github.io/posts/2025/02/07/babylon-and-tornadovm
