2. generate_synthetic_data - utility for generating synthetic MT data

Documentation

• None to date

Building on Linux

• cd makefiles
• edit the file run_make.sh to setup for your compiler
  • set the C++ compiler (e.g., cxx=g++)
  • set the MPI C++ compiler (e.g., mpicxx=mpiCC)
  • set the C++ compiler flags (e.g. cxxflags='-std=c++11 -O3 -Wall')
  • set the executable directory (e.g., exedir='../bin/raijin/gnu')
• execute run_make.sh

Windows executable

• Pre-built Windows 64-bit executables are located in bin/x64/Release

Building on Windows

• You can build (compile) the programs with the free Microsoft Visual Studio Express 2013.
• Visual Studio solution and project files are supplied.
• Open visualstudio\rjmcmcmt\rjmcmcmt.sln to compile the inversion program.
• Open visualstudio\generate_synthetic_data\generate_synthetic_data.sln to compile the synthetic data generation program.

Other software dependencies

1. cpp-utils

   • cpp-utils is a repository of C++ utility classes and functions that are used across this and several other other projects.
   • cpp-utils is included as a git submodule of this repository (see submodules).
   • only required if you are compiling the code.
   • not required if you are just going to use the precompiled executables.

2. rj-McMC

   • this is a rj-McMC library written by Rhys Hawkins, Research School of Earth Science, Australian National University.
   • download from http://www.iearth.org.au/codes/rj-MCMC/

3. Message Passing Interface (MPI)

   • see https://www.mpi-forum.org
   • Both Windows and Linux users will need to install a suitable MPI for your system.
   • The pre-compiled Windows inversion programs require Microsoft HPC Pack 2012 because thats the flavour of MPI they have been compiled and linked with.
   • They can be recompiled using MPICH or other flouvours of MPI if required.
