Hi,

I went to holdays in June 2026, had an idea for
a pi-WAM based on a Hack, the later is described here:

Emulating π-WAM in Dogelog Player
https://medium.com/2989/de9cd29c7d37

The Elements of Computing Systems
https://mitpress.mit.edu/9780262539807

In July 2026 I did the CPU and GPU experiments,
moving from emulator to native executor based in
realizing Hack as a concrete virtual machine,

and not as an abstract machine emulated in Prolog.
The GPU experiments were done in WebGPU / WGSL.
So no, I never used OpenGL Version 4.2 and later.

Also the name imageAtomicAdd indicates that it
imageAtomicAdd is rather from a render shader,
while my GPU experiment uses a compute shader.

Es specially I need GPU compute shaders, which
are not executed in lock step, but rather have
indepdendent thread state, also known as MIMD.

"In computing, multiple instruction, multiple
data (MIMD) is a technique employed to
achieve parallelism. "
https://en.wikipedia.org/wiki/Multiple_instruction,_multiple_data

MIMID showed up 2017 with NVIDIA Volta cards.
But is now realized by Intel Arc, Snapdragon Adreno
and AMD RDNA as well.

Bye
