Building from source (for linux)

Consider downloading a pre-compiled binary. If you want to compile nevertheless:

install the nvidia proprietary driver, if not yet present.

if unsure, it's probably already there
version 440.44 recommended

install Go
- https://golang.org/dl/
- set $GOPATH
install CUDA
- https://developer.nvidia.com/cuda-downloads (pick default installation path)
- or sudo apt-get install nvidia-cuda-toolkit
install a C compiler
- on Ubuntu: sudo apt-get install gcc
if you have git installed:
- go get github.com/mumax/3/cmd/mumax3
if you don't have git:
- seriously, no git?
- get the source from https://github.com/mumax/3/releases
- unzip the source into $GOPATH/src/github.com/mumax/3
- cd $GOPATH/src/github.com/mumax/3/cmd/mumax3
- go install
optional: install gnuplot if you want pretty graphs
- on ubuntu: sudo apt-get install gnuplot
use the Makefile if there is a need to recompile the cuda kernels
- make realclean && make

Your binary is now at $GOPATH/bin/mumax3
