Abstract
The zJava project aims to develop automatic parallelization
technology for programs that use pointer-based dynamic
data structures, written in Java. The system exploits paral-
lelism among methods by creating an asynchronous thread
of execution for each method invocation in a program. At
compile-time, methods are analyzed to determine the data
they access, parameterized by their context. A description
of these data accesses is transmitted to a run-time system
during program execution. The run-time system utilizes this
description to determine when an invoked method may ex-
ecute as an independent thread. The goal of this paper is to
