PLEASE MAKE IT WORK ON AMD GPU'S

Please 🙏

On Linux, you can use SCALE to compile and run it on supported AMD GPUs

Won't work on amd with scale atm....

Hi folks, I've been working over the past couple of months on porting the Alien CUDA code to ROCm/HIP. It's based on the 4.x stable branch from September 2024.

On my 7900 XTX, it appears to be significantly faster than the SCALE version (130TPS vs 53TPS on the GUI).

# needs CMake 3.31 and rocm 7.2
git clone -b 4.x-amd-hip-port https://github.com/mauri870/alien.git
cd alien
./build.sh
./run.sh # or ./cli.sh

Crunching some numbers:

Reading input
Device: AMD Radeon RX 7900 XTX
Start simulation
Simulation finished: 500 time steps, 2,934 ms, 170.4 TPS
Writing output
No output file given.

For the GUI version, it hovers around 130 TPS and ~40 FPS at 4K on the default sim. With rendering disabled (ALT+I), I can get close to 200 TPS.

Unfortunately, I don't have other AMD GPUs to test on, so if anyone wants to try it out, let me know how it goes!

@mauri870 Thank you so much. After a bit of fiddling with things I managed to build and run your fork on my 7900XT on Bazzite in an Ubuntu Distrobox with rocm installed.
