GPU-Computing macOS Big Sur vs iBuntu Lux Sur

Hello,

Let’s test this beauty from the last post on… LuxMark ;-). The thing is that I wanted to compare OpenCL. I know that OpenCL in both systems is not working fully right. I found on macOS that (multi-GPU case) clFinish(q) is slow down each time, on iBuntu -cl-fast-relaxed-math cause a black-scenes on Lux Ball… and on Darknet on OpenCL it is more things wrong, but maybe there are my bugs, so… ;-). Anyway, let’s look at the 4 x AMD Radeon RX 6900 XT in one system performance test.

iBuntu Lix Sur (why not?!), AMD Ubuntu GPU-Drivier v21.20, LuxMark 3.x, Scene Lux Ball, -cl-fast-relaxed-math (disabled, cause of errors!):

macOS Big Sur 11.5.1, Apple GPU-Driver OpenCL 1.2 (Jun 25 2021 18:15:31), LuxMark 3.x, Scene Lux Ball, -cl-fast-relaxed-math (disabled, cause of iBuntu to check the same!):

iBuntu Lix Sur (why not?!), AMD Ubuntu GPU-Drivier v21.20, LuxMark 3.x, Scene Hotel Lobby, -cl-fast-relaxed-math (disabled, cause of errors!):

macOS Big Sur 11.5.1, Apple GPU-Driver OpenCL 1.2 (Jun 25 2021 18:15:31), LuxMark 3.x, Scene Hotel Lobby, -cl-fast-relaxed-math (disabled, cause of iBuntu to check the same!):

What are the conclusions..? Like all passionate associate scientists who have to pay from own money for research equipment lab and cannot buy Radeon Pro or Instinct GPU cards, I decided to move to iBuntu. I re-tired tests on macOS Big Sur 11.5.1 I did last time. I am super happy to use iBuntu. Overall my research will be on it. I test the only macOS, and with a huge temptation cannot use macOS once it is not right, I plan to use iBuntu to not break any license. Thanks for reading, happy weekend!
