GPU accelerated micromagnetic simulator with spin-resonator coupling. The spin dynamics is coupled with an LCR resonator which represents the photon mode. The code is modified based on Mumax 3.10.

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/
- Ubuntu:
- if you have git installed:
go get github.com/jthou0129/Mumax3_spinresonator/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/jthou0129/Mumax3_spinresonator/cmd/mumax3go install
- optional: install gnuplot if you want pretty graphs
- Ubuntu:
sudo apt-get install gnuplot
- Ubuntu:
Your binary is now at $GOPATH/bin/mumax3
To do all at once on Ubuntu:
sudo apt-get install git golang-go gcc nvidia-cuda-toolkit nvidia-cuda-dev nvidia-340 gnuplot
GOPATH=$HOME go get -u -v github.com//jthou0129/Mumax3_spinresonator/cmd/mumax3
