Abstract

Recent networks and network interfaces promise remarkable communication performance with very little overhead, but current software structures impose substantial overhead that prevents applications from achieving the benefits of these new architectures. We propose a new software structure that eliminates much of the overhead while preserving the ease of programming of current systems. Our architecture relies on the compiler to bridge the gap between high-level application programs and low-level communication primitives. The compiler incorporates application code into message handlers using a new runtime mechanism called optimistic active messages.
