Introduction

The Pensieve project aims at providing programmers a virtualized memory consistency model - i.e. a memory consistency model that is not necessarily the same as that provided by the underlying hardware, and to make it possible for the programmer to specify what that consistency model should be. Moreover, the Pensieve compiler aims to do this while still providing good program performance.

We are developing a compiler infrastructure using the Jikes Research Virtual Machine from IBM. This involves design and implementation of program analyses and transformations.
