Loosely Coupled Parallel Processing at Fermilab

Distributed Processing Over Loosely Coupled Networks

Several systems exist that distribute data streams to a single task installed at client machines, while others migrate the whole job to a machine with predetermined processing capabilities. In this paper we propose a hybrid system, DISTPRO, that allows the distribution of any task and/or data stream to participating clients. An experimental client– server approach is discussed and implemented. ...

Parallel execution of functional programs on loosely coupled multiprocessor systems

It has been suggested that functional programs are suitable for programming parallel computers owing to their inherent parallelism. We propose a parallel evaluation model of functional programs based on the STG(Spineless Tagless G-machine) model proposed for sequential evaluation, and describe our parallel implementation of a functional language Gofer on the AP1000 parallel computer.

Loosely-Coupled Processes

A system of processes in which the interactions are solely through messages is often called loosely-coupled. Such systems are attractive from a programming viewpoint. They are designed by decomposing a specification into its separable concerns, each of which could then be implemented by a process; the operation of the system can be understood by asserting properties of the message sequences tra...

Survivable Loosely Coupled Architectures

We present an approach to provide a fault-tolerant and secure service for sealed-bid auctions. The solution is designed for a loosely coupled publish-subscribe system. It employs multiple auction servers and achieves validity and security properties through application of secret-sharing methods and public-key encryption and signatures. It can tolerate Byzantine failures of one third of the auct...
