Input-driven dynamic execution prediction of streaming applications

Abstract

Streaming applications are promising targets for effectively utilizing multicores because of their inherent amenability to pipelined parallelism. While existing methods of orchestrating streaming programs on multicores have mostly been static, real-world applications show ample variations in execution time that may cause the achieved speedup and throughput to be sub-optimal. One of the principle challenges for moving towards dynamic orchestration has been the lack of approaches that can predict or accurately estimate upcoming dynamic variations in execution efficiently, well before they occur.
