Introduction

In this report, we introduce HPJava language, a programming language extended from Java [1] for parallel processing, targeting at multi-processor system with distributed memory.

• Structured SPMD programming, a SPMD program, well defined loosely synchronization mechanism among organized process group.
• Global name space, global addressed array with different distribute patterns among processors.
• Collective communication through collective communication to access non-local data, data parallel applications can have dead-lock free communication.
• Hybrid of data and task parallel programming facilitating both data parallel and task parallel programming.
• Flexible for future extension.
