#### The very long (Weekly) tests ####

# Note: The cross product of all possible PARSEC tests is huge, and there is
# little value in doing all. Therefore a sensible selection covering all
# benchmarks have been chosen.
#
# Note: At present the MESI_Two_Level protocol does not appear to work
# correctly with the SwitchableProcessor. As such they are commented out. This
# issue is documented here: https://gem5.atlassian.net/browse/GEM5-1085.
