Compiling

Prerequisites:

• cmake-3.5 or later
  • cmake must be in your PATH
• A modern C++ compiler (g++, icpc, pgCC, clang++, cl)
• MPI (openMPI, mpich)
  • mpiexec must be in your PATH
• Random123
  • export RANDOM123_INC_DIR=/some/path/Random123-1.08/include
• Gnu Scientific Library
  • gsl-config must be in your PATH
• python 2X

Only needed for testing:

• numdiff
  • numdiff must be in your PATH

Configure:

• Use a separate build directory

    $ mkdir build
    $ cmake ../Draco.git

• For Cray PrgEnv, you need to prime the CMakeCache.txt

    $ cmake -C ../Draco.git/config/CracyConfig.cmake ../Draco.git

Optional components:

• Additional libraries will be built if certain features are available in the build environment:
  • lapack_wrap will be built if LAPACK or equivalent is available.
  • cdi_eospac will be built if LANL's libeospac is available.
  • device will be built if the CUDA toolkit is available and the build machine has a GPU.
  • plot2D will be built if the Grace headers and library are found.

Build:

   $ make

Test:

   $ ctest

Install:

   $ make install
