Programs for phonon transmission and thermal conductance calculation for
ballistic systems.

This is an MPI version for linux systems

The directory source/ contains the source codes in fortran 90.  To compile,
cd to source, modify the Makefile to suit f90 compiler options to
your system.  Make sure MPI and lapack are installed and LIBS pointing to it 
correctly. 

After issue the make command, the executable will be put in 
exe/green.  Start the program with, e.g., mpirun -np 4 ./green

The input files must be in data/input/*.dat and data/runparameter/*, the
parameter file controls the sample points, delta, and other input choices.
The output directory data/output must be created.  Sample input files
are in data/ directory.  Force constants are in units of 
10 Newton/(meter*amu).  See source/input/input.f90 for input format
details.  conductance kappa is in units of nW/K. See 
source/main/main_ballistic.f90 in the function output_green() for 
units of omega. Some comments are in Chinese.
