JaBEE: framework for object-oriented Java bytecode compilation and execution on graphics processor units

There is an increasing interest from software developers in executing Java and .NET bytecode programs on General Purpose Graphics Processor Units (GPGPUs). Existing solutions have limited support for operations on objects and often require explicit handling of memory transfers between CPU and GPU. In this paper, we describe a Java Bytecode Execution Environment (JaBEE) which supports common object-oriented constructs such as dynamic dispatch, encapsulation and object creation on GPUs. This experimental environment facilitates GPU code compilation, execution and transparent memory management. We compare the performance of our approach with CPU-based and CUDA-C-based code executions of the same programs. We discuss challenges, limitations and opportunities of bytecode execution on GPGPUs.
