# WORK: It aims to :
#
#      - Treat output timing from the sx8brodie target for 
#        mon, mpi & omp runs
#     *- compare it to a reference version 
#
# * this step is performed only if a reference tag 
#   is specified with the -t option and if files exist.
#   See the Makefile under ./config/NVTK directory
