Abstract
New parallel computers are emerging, but developing
efficient scientific code for them remains difficult. A scientist
must manage not only the science-domain complexity but
also the performance-optimization complexity. HERCULES is
a code transformation system designed to help the scientist to
separate the two concerns, which improves code maintenance,
and facilitates performance optimization. The system combines
three technologies, code patterns, transformation scripts and
compiler plugins, to provide the scientist with an environment
to quickly implement code transformations that suit his needs.
Unlike existing code optimization tools, HERCULES is unique
in its focus on user-level accessibility. In this paper we discuss
the design, implementation and an initial evaluation of
HERCULES.
