The CLEO project [2], centered at Cornell University, is alarge-scale high energy physics project. The goals of the projectarise from an esoteric question---why is there apparently so littleantimatter in the universe?---and the computational problems thatarise in trying to answer this question are quite challenging. To answer this question, the CESR storage(More)
This paper describes the design and implementation of a fault-tolerant CORBA naming service-CosNamingFT. Every CORBA object is accessed through its Interoperable Object Reference (IOR), which is registered with the CORBA name service. The name service therefore is a critical gateway to all objects in a distributed system; to avoid having a single point of(More)
The goal of the Nile project is to develop an inexpensive, scalable, fault-tolerant, widely distributed job processing environment. On the systems side, Nile must manage and provide transparent access to hundreds of commodity processors spread across the United States, and a distributed database that will exceed 100 terabytes. These are scales not commonly(More)
In this tutorial, I will focus on the roles, types, and issues of middleware. I will give a short overview of the software problems that middleware addresses and (mostly) solves. I will do a survey of the different kinds of middleware and their applicability to diverse problem domains. I will spend somewhat longer discussing, with examples, CORBA, RMI, and(More)
