v.3.1.6 (Big Smoke)
This is the v.3.1.6, codenamed Big Smoke, release of gprMax.
Version 3.1.6 contains general usability and performance improvements, as well as the specific enhancements and bug fixes since v.3.1.5 (see history for details).
v.3.1 continues our whisky-based naming, and is also a reference to the cities of Edinburgh (Scotland) and San Francisco (USA). Why? Because the development of v.3.1 was funded, through a research project, by Google.
The most significant feature of this release is the ability for simulations to utilise general-purpose computing using graphics processing units (GPGPU). We have used NVIDIA's Compute-Unified Device Architecture (CUDA). Our testing on both consumer and data centre NVIDIA GPU cards has shown dramatic performance increases over our parallelised CPU (OpenMP) implementation.
You can read about how to use the GPU functionality and find all the features of gprMax described in detail in the User Guide (http://docs.gprmax.com)
Please report any bugs with code via Issues on GitHub.
