The Amber system: parallel programming on a network of multiprocessors
Jeffrey S. Chase, F. Amador, Edward D. Lazowska, Henry M. Levy, Ryan S. Littlefield · 1989
This paper describes a programming system called Amber that permits a single application program to use a homogeneous network of computers in a uniform way, making the network appear to the application as an integrated multiprocessor. Amber is specifically designed for high performance in the case where each node in the network is a shared-memory multiprocessor.
