Talk Title: Automatic Parallelization with Hy

brid Analysis

Talk Abstract:
Hybrid Analysis (HA) is a compiler t

echnology that can seamlessly
integrate all static and run-time analysi

s of memory references into
a single framework capable of generating su

fficient information for
most memory related optimizations.

In t

his talk we will present Hybrid Analysis as a framework to perform
auto

matic parallelization of loops. For the cases when static analysis
does
not give conclusive results we extract sufficient conditions which
ar

e then evaluated dynamically and can (in)validate the parallel execution of loops. The HA framework has been fully implemented in the Polaris

speedups superior to the Intel Ifort compiler.
