Title : Perking Up Code: Architecting High-Performing Dynamic Compilation Systems for the Future

Abstract : Dynamic Compilation represents a unique opportunity to adapt application code to workload profiles. Dynamic compilation offers significant advantages over traditional  workloads because each instance of the code can be adapted to the specific circumstances, represented by a combination of user workload and user environment. Thus, applications can continue to be optimized for new systems and processor technologies even as new hardware capabilities become available, or as workload behavior changes over time. Dynamic Compilation also offers advantages to software developers over feedback directed profile based optimization because it does not affect ISV build and application validation processes by requiring to build and operate “reference environments” to collect execution profiles.

Reflecting these advantages, dynamic compilation based technologies have been gaining increasingly mainstream acceptance over the past decade. To further improve the acceptance for dynamic compilation technologies, and bring more dynamic optimization technologies from the research labs into the mainstream, our community has to work on two key goals: allow ever more aggressive program transformations while guaranteeing full correctness, and reducing the overheads imposed by dynamic compilation. We will discuss how co-designing processor architecture can offer important support in achieving both goals, and describe recent innovations in state of the art processors to support for JIT and dynamic code optimization technologies.
