A pyCUDA based Metropolis Monte Carlo simulator for 2D-magnetism systems. This code uses NVIDIA CUDA architecture wrapped by a simple python wrapper to work. To use, clone the repository using
git clone https://github.com/arkavo/CUDA-METRO.git
into a directory of choice. Creating a new python3 environment is recommended to run the code.
To setup the environment after creation, simply run pip install -r requirements.pip
Some template codes have already been provided under folder /src along with sample input files in /inputs and running configurations in /configs
To run a vector analysis, simple execute python test_main.py <config file name> (main config file is /configs/test_config.json)
After execution, an output folder will be created with name <prefix>_<material>_<date>_<time> with .npy files in them containing spin data in 1D array form as [s1x s1y s1z s2x s2y.........sny snz] and an additional metadata.json file containing the details of the run.
For casual viewing, it is advised to use the in-built viewer as python test_view.py <folder name> to provide visuals of the spin magnitudes in 3 directions as well as a top-down vector map of the spins.
To run a Curie temperature analysis, execute python tc_sims.py after configuring the appropriate config file in /configs/tc_config.json.
After the run, a graph of temperature vs magnetization and temperature vs susceptibility will be auto generated.
