The key open architectural question is the nature of the network interface or the <EM> communication architecture</EM>:its hardware organization and logical abstraction as a basis for communication.<p>Active Messages represent a RISC approach to communication, providing simpleprimitives, rather than solutions, which expose the full hardware performance to higher layers. Active Messages are intended to serve as a substrate for building libraries that provide higher-level communication abstractions and for generating communication code from a parallel-language compiler, rather than for direct use by programmers. It is currently in use at UC Berkeley by the <!WA1><A HREF="http://now.cs.berkeley.edu/Fastcomm/fastcomm.html">Fast Communication</A> layers (sockets, RPC and MPI), the <!WA2><A HREF="http://now.cs.berkeley.edu/Xfs/xfs.html">xFS</A> parallel file system, the <!WA3><A HREF="http://http.cs.berkeley.edu/projects/parallel/castle/split-c/split-c.html">Split-C </A> and Id compilers, as well as in other libraries like Scalapack.<p>This project investigates Active Messages on a broad range of hardware, including a dedicated message processor per node (Intel Paragon and Myrinet)an FDDI interface at the graphics bus of a high end workstation (HP 735 with Medusa), and a conventional interface to the next generationLAN (Sparc 10 with Sahi-1 ATM). We will thus demonstrate concepts by construction and evaluate them on real programs on real machines. The result will be a clearer understanding of the communication architecture and trade-offs in the hardware organization of the network interface. <!WA4><A href="http://now.cs.berkeley.edu/Papers/papers.html"><H3>Search for Papers</H3></a><HR><H3> Software Releases</H3><!WA5><A href="http://now.cs.berkeley.edu/AM/lam_release.html"> Lanai Active Messages </a><p><HR><H3>People</H3>Professors<UL><LI><!WA6><A href="http://www.cs.berkeley.edu/~culler/index.html">David E.
