subhacom / traub2005_gfortran Goto Github PK

This is gfortran + mpif77 version of Traub 2005 code (originally modified for g77 by Michael Hines). The makefile has been modified to generate the executables for figures 2, 6, 7A-D and the serial version.

make groucho_fig2

make groucho_fig6

make groucho_fig7A

make groucho_fig7B

make groucho_fig7C

make groucho_fig7D

make groucho_serial

will create the corresponding executables. For all but the last one you need mpif77 with gfortran. The last one can be done with gfortran without mpi.

To run a specific executable, except groucho_serial, use the run_groucho.sh script. The argument should be the specific groucho executable you want to run. Run groucho_serial directly:

./groucho_serial

This has been tested on the following system (the output of mpif77 -v)

Using built-in specs.
