A Distributed Virtual Machine for Parallel Graph Reduction

We present the architecture of nreduce, a distributed virtual machine which uses parallel graph reduction to run programs across a set of computers. It executes code written in a simple functional language which supports lazy evaluation and automatic parallelisation. The execution engine s away details of parallelism and distribution, and uses JIT compilation to produce efficient code. This work is part of a broader project to provide a programming environment for developing distributed applications which hides low-level details from the application developer. The language we have designed plays the role of an intermediate form into which existing functional languages can be transformed. The runtime system demonstrates how distributed execution can be implemented directly within a virtual machine, instead of a separate piece of middleware that coordinates the execution of external programs.
