# The following patch overrides the check for CPU throttling.
# Note that this means that the automatic tuning at the heart of the ATLAS library will be nonsensical,
# likely resulting in degraded performance.  If at all possible, use a custom-installed version of
# ATLAS built with CPU throttling disabled.  There are some helpful instructions in the INSTALL.txt file.
