The Amoeba project is a research effort aimed at understanding how to connect multiple computers in a seamless way [16, 17, 26, 27, 31]. The basic idea is to provide the users with the illusion of a single powerful timesharing system, when, in fact, the system is implemented on a collection of machines, potentially distributed among several countries. This(More)
Most modern network protocols give adequate support for traditional applications such as file transfer and remote login. Distributed applications, however, have different requirements (e.g., efficient at-most-once remote procedure call even in the face of processor failures). Instead of using ad hoc protocols to meet each of the new requirements, we have(More)
Amoeba is the distributed system developed at the Free University (VU) and Centre for Mathematics and Computer Science (CWI), both in Amsterdam. Throughout the project's ten-year history, a major concern of the designers has been to combine the research themes of distributed systems, such as high availability , use of parallelism and scalability, with(More)
Many portable compilers generate an intermediate code that is subsequently translated into the target machine's assembly language. In this paper a stack-machine-based intermediate code suitable for algebraic languages (e.g., PASCAL, C, FORTRAN) and most byte-addressed mini-and microcomputers is described. A table-driven peephole optimizer that improves this(More)
Remote Procedure Call (RPC) is a widely used communication mechanism in local network based distributed operating systems. It is simple , fast, and straightforward to implement. However, when two or more distant distributed systems are connected, problems arise concerning the protocols, locating services, and other issues. To solve these problems, gateways(More)
<italic>The Amsterdam Compiler Kit is an integrated collection of programs designed to simplify the task of producing portable (cross) compilers and interpreters. For each language to be compiled, a program (called a front end) must be written to translate the source program into a common intermediate code. This intermediate code can be optimized and then(More)
Distributed operating systems have been in the experimental stage for a number of years now, but few have progressed to the point of actually being used in a production environment. It is our belief that the reason lies primarily with the performance of these systems---they tend to be fairly slow compared to traditional single computer systems. The Amoeba(More)
Amoeba is a capability-based distributed operating system designed for high performance interactions between clients and servers using the well-known RPC model. The paper starts out by describing the architecture of the Amoeba system, which is typified by specialized components such as workstations, several services, a processor pool, and gateways that(More)
University researchers love nothing better than to invent a new programmin g language. The trouble is, unless the language is only intended for mental exercise , the next step is writing a compiler for the new language, which is a lot of work. Typically one makes a prototype compiler that runs slowly and produces awful cod e for one particular CPU that(More)
