WILSON LOOPS
The programs compute rectangular Wilson loops on imported gauge configuration.
The links are smeared to (i) define a static action and (ii) to construct an
operator basis which results in a Wilson loop correlation matrix. See

for details.
The currently supported boundary conditions are periodic and open. For a
description of how-to run the program and the output see the README in the
main subdirectory.
PROGRAM FEATURES
All programs parallelize in 0,1,2,3 or 4 dimensions, depending on what is
specified at compilation time.
OPENQCD PACKAGE
All programs use the openQCD package modules as library. The package has to
be present at compile time in a directory to be specified in the Makefile.
The currently supported version is openQCD-1.4.
COMPILATION
The compilation of the programs is in accordance with openQCD-1.4. See there for
details.
AUTHORS
The initial release of the wloop package was written by Björn Leder. Initial
support for open boundary conditions was added by Jacob Finkenrath.
ACKNOWLEDGEMENTS
An early version of the code is based on a Wilson loop program by Nazario Tantalo.
