ppOpen-AT: A Directive-base Auto-tuning Language

Abstract: ppOpen-AT is a domain-specific language designed to ease the workload for developers creating libraries with auto-tuning (AT) capabilities. It consists of a set of directives that allow for the automatic generation of code necessary for AT by placing annotations in the source program. This approach significantly reduces the effort required by numerical library developers. This technical report details the implementation of the AT software and its extended functions, and provides an explanation of the internal specifications of ppOpen-AT.
