Building from source

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
• v340 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
  • Ubuntu: sudo apt-get install gcc
  • MacOSX: https://developer.apple.com/xcode/download/
  • Windows: http://sourceforge.net/projects/mingw-w64/
• 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
  • Ubuntu: sudo apt-get install gnuplot

Your binary is now at $GOPATH/bin/mumax3

To do all at once on Ubuntu:

sudo apt-get install git golang-go gcc nvidia-cuda-toolkit nvidia-cuda-dev nvidia-340 gnuplot
export GOPATH=$HOME go get -u -v github.com/mumax/3/cmd/mumax3
