Details: - Increased the double-precision real MT threshold (which controls whether the sup implementation kicks for smaller m dimension values) from 80 to 180, and this change was made for both haswell and zen subconfigurations. This is less about the m dimension in particular and more about facilitating a smoother performance transition when m = n = k.
For more information on sub-configurations and configuration families in BLIS, please read the Configuration Guide, which can be viewed in markdown-rendered form from the BLIS wiki page.
If you don't have time, or are impatient, take a look at the config_registry
file in the top-level directory of the BLIS distribution. It contains a
grammar-like mapping of configuration names, or families, to sub-configurations,
which may be other families. Keep in mind that the / notation:
<config>: <config>/<name>
means that the kernel set associated with <name> should be made available to
the configuration <config> if <config> is targeted at configure-time.
(Some configurations borrow kernels from other configurations, and this is how
we specify that requirement.)
