Implementing communication latency hiding in high-latency computer networks

Abstract

We present a latency hiding protocol for asynchronous message passing in UNIX environments. With this protocol distributed parallel computing can be utilized to solve applications, which can be structured such that useful computation overlaps communication, in a more efficient way than possible with current standard technologies. To maintain portability our protocol is layered on top of the Berkeley socket interface and the TCP/IP protocol. We present experimental data that validate our model on latency hiding and demonstrate the capability of our implementation.
