Arne Vansteenkiste’s github projects

This page contains a few picks from my repos at github.com/barnex

mumax3

mumax3 is a GPU-accelerated micromagnetic simulator with ~1000 active users worldwide. It is cited in over 900 scientific publications.

bruteray

bruteray is a hobby ray tracer employing physically accurate light transport to generate realistic images.

fig

rusty-mazes

rusty-mazes is a 2D puzzle/maze game + editor written in Rust.

coffee-cpu

After drinking too much coffee, @MathiasHelsen and I built a softcore CPU on FPGA. The coffee-cpu has a 14-bit memory space. It has an assembler and can solve a few challenges from projecteuler.net.

// This test program cycles the hex display
// through all 16-bit values

#def display 0x3FFF
#def Rcount R1

#label _start
XOR   R0     R0       A R0     -cmp
STORE Rcount display  N R0     -cmp
ADD   Rcount 1        A Rcount -cmp
ADD   R0     _start   A PC     -cmp

hamstr-game

hamstr-game is a 2D platformer game with ray-traced shadows written in Rust.

just-in-time-compiler

This is a just-in-time compiler for mathematical expressions like x + sqrt(y - 1). It does constant-folding and registerization. The resulting x86 binary machine code can be immediately executed for, e.g., super-fast function plotting.

fig

ev3cam

ev3cam detects motion in a webcam stream (using gstreamer), so that a LEGO mindstorms knows where to aim.

fig

Game of life

This is an insanely optimized implementation of Conway’s Game of Life (a Turing-complete “board game”). With extreme bit-fiddling, it achieves a ~300x speed-up over a naive implementation.

fig

SetupSoftware

Not-so-aptly-named software to control the Magneto-Optical Scanning Microscope at Dynamat lab, UGent.

fig

Raspberry heat

Home temperature control with Raspberry Pi and a web interface.

fig

Bare-metal raspberry pi

Bare-metal kernel image for raspberry Pi. It writes PI on the display. Inspired by baking pi but written mostly in C.

fig

Go bindings for CUDA

Go bindings for CUDA, my most starred project.

fig

arnecompiler

This is a hobby compiler I wrote a really long time ago (2010). It can solve the first few problems of projecteuler.net.

Language example:

include(int)

variable(int answer, 0)

for(variable(int i, 0), _lessl(i, 995), _incl(i), block(
  variable(int product, 1)
  for(variable(int j, 0), _lessl(j, 5), _incl(j), block(
    product(_mull(product, get_array(_addl(i, j))))
  ))
  if(_greaterl(product, answer)
    answer(product)
  )
))

print_int(answer)
