In current Java implementations, Remote Method Invocation is too slow for high performance computing. Since Java’s object serialization often takes 25%–50% of the time needed for a remote invocation, an essential step towards a fast RMI is to reduce the cost of serialization.

The paper presents a more efficient object serialization in detail and discusses several show-stoppers we have identified in Sun’s official serialization design and implementation. We demonstrate that for high performance computing some of the official serialization’s generality can and should be traded for speed. Our serialization is written in Java, can be used as a drop-in replacement, and reduces the serialization overhead by 81% to 97%.
