Hi, Why I forget something, that was never on my mind. This here is hardly about rockets: 11.4 Giga Lips with a Budget Laptop https://github.com/Jean-Luc-Picard-2021/gigabudget So stop glue sniffing. Got it? Your are just confused. I don't care about SpaceX, that Composer was acquired by SpaceX was just a factual thing. Bye Disclaimer: Who knows, maybe somebody picks up pi-calculus and/or WAM for rocket engineering, I do not primarily exclude it. But its not on my mind, so I cannot forget something which I don't care about.

Hi,
Mostlikely this is faster with MIMD,
than with SIMD. Draw a Mandel Brot Figure:
mandelbrot
https://compute.toys/view/213
Why, because each pixel has a different
result i, since this loop has a break:
for (i = 0; i < count; i++) {
if (z_re * z_re + z_im * z_im > 4.0) {
break;
}
let new_re = z_re * z_re - z_im * z_im;
let new_im = 2.0f * z_re * z_im;
z_re = c_re + new_re;
z_im = c_im + new_im;
}
So a sheduler balancer, that uses independent
thread state (MIMD), from a post NVIDIA Volta
type GPU, can squeeze out more computation,
than a lock step (SIMD) scheduler, from a
pre NVIDIA Volta GPU. I guess I will use that
as a balancing example for pi-WAM.
Bye
