HPC-DGTD

Quick start with CMake

CPU build:

  • mkdir <dgtd-build-dir> ; cd <dgtd-build-dir>
  • cmake <dgtd-source-dir>
  • make -j 4 (assuming "UNIX Makefiles" generator)

GPU build:

(this build requires CMake 3.8 or newer)

  • mkdir <dgtd-build-dir> ; cd <dgtd-build-dir>
  • cmake <dgtd-source-dir> -DDGTD_USE_CUDA=YES
  • make -j 4

Building with CMake

The MaxwellTD build system consists of two steps: configuration and compilation.

The configuration step can be used to adjust paths to external libraries, compilers, flags, etc, similar to any CMake build system. It is performed by running

  • mkdir <dgtd-build-dir> ; cd <dgtd-build-dir>
  • cmake <dgtd-source-dir> [OPTIONS] ...

The OPTIONS are of the form -D<VARIABLE>=<VALUE>, e.g. -DDGTD_USE_CUDA=YES. Alternatively, the options can be specified with an input file:

  • cd <dgtd-source-dir>/config
  • edit defaults.cmake

Configuration variables (CMake)

See the configuration file config/defaults.cmake for the default settings.

Note: the option DGTD_USE_CUDA requires CMake version 3.8 or newer!

DGTD features/options (CMake)

  • DGTD_USE_OPENMP
  • DGTD_USE_DOUBLE
  • DGTD_USE_DOUBLE_TS
  • DGTD_USE_CUDA
  • DGTD_USE_OPENCL
  • DGTD_USE_CUDA_OPENCL
