A major challenge in Metacomputing Systems (Computational Grids) is to effectively use their shared resources, such as compute cycles, memory, communication network, and data repositories, to optimize desired global objectives. In this paper we develop a unified framework for resource scheduling in metacomputing systems where tasks with various requirements(More)
Foreword To live, learn, and work successfully in an increasingly complex, information-rich and knowledge-based society, students and teachers must utilize technology effectively. Within a sound educational setting, technology can enable students to become: • Capable information technology users • Information seekers, analyzers, and evaluators • Problem(More)
The Management System for Heterogeneous Networks (MSHN) is a resource management system for use in heterogeneous environments. This paper describes the goals of MSHN, its architecture, and both completed and ongoing research experiments. MSHN’s main goal is to determine the best way to support the execution of many different applications, each with its own(More)
In this paper, we study a general mapping problem where a set of independent tasks compete for the shared resources of a Grid environment. Tasks have resource co-allocation requirements. Each task requires multiple and different resources to be allocated simultaneously. At run-time, a task may release its allocated resources during its execution and before(More)
In this paper, we study the problem of mapping a set of independent paths onto a heterogeneous real-time system. Each path is a pipeline of several stages where each stage consists of one application. Each path has latency and throughput requirements that have to be satisfied. The general goal of this problem is to find an initial static mapping of all(More)
