DescriptionMaximizing the performance on modern hardware platforms
has become more and more difficult, due to different
levels of parallelism and complicated memory
hierarchies. Auto tuning can help developers to address
these challenges by writing code that automatically
adjusts to the underlying hardware platform. AutoTuneTMP
is a new C++-based auto tuning framework that uses
just-in-time compilation to enable runtime-instantiable
C++ templates. We use C++ template metaprogramming to
provide data structures and algorithms that can be used
to develop tunable compute kernels. These compute
kernels can be tuned with different optimization
strategies. We demonstrate for a first prototype the
applicability and usefulness of our approach by tuning 6
parameters of a DGEMM implementation, achieving 68% peak
performance on an Intel Skylake processor.
