# Minimum CPU requirements:
# x86: Pentium 4 (Prescott, circa 2004)
# x86_64: Opteron (circa 2003)
# These are the settings used for the generic builds. Performance will
# be poor on modern systems. The goal of the Hydra builds is simply to
# support as many systems as possible. OpenBLAS may support older
# CPU architectures, but you will need to set 'config.openblas.target'
# and 'config.openblas.preferLocalBuild', which will build it on your
# local machine.
