Automatic Parallelization with Hybrid Analysis
by Dr. Lawrence Rauchwerger (Texas A&M University)
Hybrid Analysis (HA) is a compiler technology that can seamlessly integrate all static and run-time analysis of memory references into a single framework capable of generating sufficient information for most memory related optimizations.
In this talk, we will present Hybrid Analysis as a framework to perform automatic parallelization of loops. For the cases when static analysis does not give conclusive results, we extract sufficient conditions which are then evaluated dynamically and can (in)validate the parallel execution of loops. The HA framework has been fully implemented in the Polaris compiler and has parallelized 22 benchmark codes with 99% coverage and speedups superior to the Intel Ifort compiler.
