An autotuning protocol to rapidly build autotuners

摘要

While autotuning has become a valuable tool for the high-performance computing (HPC) community to achieve "performance portability," that is, the program runs on the new architecture correctly and with the expected performance, it is not easy. Currently, each auototuner seems to be built from scratch. The authors have a track record in autotuning, and have leveraged this to propose an autotuning framework, including a knowledge base and provision for a learner (they show a decision tree, but state that others are feasible).
