GridFoRCE: A comprehensive resource kit for teaching grid computing

IEEE TRANSACTIONS ON EDUCATION 2007年第1期50卷 10-16页

作者： Ramamurthy, Bina SUNY Buffalo Comp Sci & Engn Dept Buffalo NY 14260 USA

A comprehensive suite of pedagogical resources is presented that will enable an instructor to embed grid computing concepts in a traditional distributed system course. Rapidly advancing Internet technologies and ever expanding application domains have created excitement in teaching distributed systems. Many fundamental concepts developed decades earlier, such as remote procedure calls and multithreading, have come to play key roles in modern distributed systems. Standards such as eXtensible Markup Language (XML) and Simple Object Access Protocol (SOAP) have been developed to enable interoperability among heterogeneous distributed systems. However, a plethora of new paradigms, a wide variety of technological choices, and short cycles of technological obsolescence challenge the introduction of these important concepts into a distributed systems course. This paper describes how the author addressed these challenges in teaching grid computing. The paper also provides details of the resources developed during this process. The pedagogical resource kit developed includes course curriculum, lecture notes, a set of laboratory assignments, a Globus Toolkit-based experimental grid adapted to classroom assignments, and valuable lessons learned from the course offerings during the past two years. The material provided in this paper is expected to help to "jumpstart" educators considering the introduction of grid computing into their curricula.

distributed execution of a single program is becoming increasingly important for embedded real-time systems. The single program approach to distributed programming allows the advantages of language level software engineering developments to be fully realized across machine boundaries. This paper examines some of the fundamental issues and tradeoffs involved in the translation and execution of programs written in the Ada language and intended for distributed execution. The memory access architecture, binding time and degree of system homogeneity are the three basic dimensions in terms of which target systems can be described. Library subprograms and library packages are identified as natural distributable units of the language. The program to process/memory mapping and the unit of the language to be distributed are the key issues in the distribution of Ada. The implications of various alternatives for these are analyzed.

In 1916, Albert Einstein published his famous general theory of relativity, which contains the rules of gravity and provides the basis for modern theories of astrophysics and cosmology. For many years, physicists, astrophysicists, and mathematicians have striven to develop techniques for unlocking the secrets contained in Einstein's theory of gravity;more recently, computational-science research groups have added their expertise to the endeavor Because the underlying scientific project provides such a demanding and rich system for computational science,techniques developed to solve Einstein's equations will apply immediately to a large family of scientific and engineering problems. The authors have developed a collaborative computational framework that allows remote monitoring and visualization of simulations, at the center of which lies a community code called Cactus. Many researchers in the general scientific computing community have already adopted Cactus, as have numerical relativists and astrophysicists. This past June, an international team of researchers at various sites ran some of the largest such simulations in numerical relativity yet undertaken, using a 256 processor SGI Origin 2000 supercomputer at NCSA.

HERMES LANGUAGE EXPERIENCES

引用

SOFTWARE-PRACTICE & EXPERIENCE 1995年第4期25卷 389-402页

作者： KORFHAGE, W GOLDBERG, AP NYU COURANT INST MATH SCI DEPT COMP SCI NEW YORK NY 10012 USA

We recount and examine experiences with Hermes, an experimental language for programming distributed systems, Hermes has several unusual language features, including compile-time checking of data initialization, representation independent data aggregates, and an integrated process model. To facilitate compile-time initialization checking, Hermes stores data in tables and does not expose pointers, We study these features in light of the experiences of Hermes users around the world, analyzing the strengths and weaknesses of the language.

distributed-Memory FastFlow Building Blocks

引用

INTERNATIONAL JOURNAL OF PARALLEL programming 2023年第1期51卷 1-21页

作者： Tonci, Nicolo Torquati, Massimo Mencagli, Gabriele Danelutto, Marco Univ Pisa Comp Sci Dept Pisa Italy

We present the new distributed-memory run-time system (RTS) of the C++-based open-source structured parallel programming library FastFlow. The new RTS enables the execution of FastFlow shared-memory applications written using its Building Blocks (BBs) on distributed systems with minimal changes to the original program. The changes required are all high-level and deal with introducing distributed groups (dgroup), i.e., logical partitions of the BBs composing the application streaming graph. A dgroup, which in turn is implemented using FastFlow's BBs, can be deployed and executed on a remote machine and communicate with other dgroups according to the original shared-memory FastFlow streaming programming model. We present how to define the distributed groups and how we faced the problem of data serialization and communication performance tuning through transparent messages' batching and their scheduling. Finally, we present a study of the overhead introduced by dgroups considering some benchmarks on a sixteen-node cluster.

THE EVOLUTION OF THE SR LANGUAGE

引用

distributed COMPUTING 1986年第3期1卷 133-149页

作者： ANDREWS, GR OLSSON, RA 1. Department of Computer Science The University of Arizona 85721 Tucson AZ USA

As a result of our experience, the SR distributed programming language has evolved. One change is that resources and processes are now dynamic rather than static. Another change is that operations and processes are now integrated in a novel way: all the mechanisms for process interaction — remote and local procedure call, rendezvous, dynamic process creation, and asynchronous message passing — are expressed in similar ways. This paper explains the rationale for these and other changes. We examine the fundamental issues faced by the designers of any distributed programming language and consider the ways in which these issues could be addressed. Special attention is given to the design objectives of expressiveness, simplicity, and efficiency.

CLUSTER COMPUTING-THE JOURNAL OF NETWORKS SOFTWARE TOOLS AND APPLICATIONS 2024年第8期27卷 10235-10244页

作者： Alimoglu, Alper Ozturan, Can Bogazici Univ Dept Comp Engn Istanbul Turkiye

Scientific workflows are essential for many applications, enabling the configuration and execution of complex tasks across distributed resources. In this paper, we contribute an Ethereum blockchain-based scientific workflow execution manager, which distributes workflows to run on cluster computing providers that utilize the Slurm workload manager to execute them. We extended our blockchain-based autonomous resource broker called eBlocBroker, which is a DAO-based decentralized coordinator, by providing distributed workflow execution via blockchain. Through various tests, we demonstrate how our eBlockBroker autonomous organization, which is programmed as a smart contract, can manage scientific workflow submission, scheduling, and execution on cluster computing providers. The utilization of blockchain for distributed workflow execution is a new concept. We are motivated because our system has been developed with e-Science in mind where scientific workflows are widely utilized.

The WITCH experiment is a medium-scale experimental set-up located at ISOLDE/CERN. It combines a double Penning trap system with,a retardation spectrometer for energy measurements of recoil ions from beta decay. For a correct operation of such a set-up a whole range of different devices is required. Along with the installation and optimization of the set-up a computer control system was developed to control these devices. The CS-Framework that is developed and maintained at GSI, was chosen as a basis for this control system as it is perfectly suited to handle the distributed nature of a control *** report here on the required hardware for WITCH, along with the basis of this CS-Framework and the add-ons that were implemented for WITCH.

COMPUTING IN SCIENCE & ENGINEERING 2013年第5期15卷 56-67页

作者： Shen, Bo-Wen Nelson, Bron Cheung, Samson Tao, Wei-Kuo Univ Maryland College Pk MD 20742 USA NASA Goddard Space Flight Ctr Greenbelt MD 20771 USA

One of the current challenges in tropical cyclone research is how to improve our understanding of TCs' interannual variability as well as climate change's impact. Modern advances in global modeling, visualization, and supercomputing technologies at NASA show potential, but scalability is an issue. Recent improvements to the multiscale modeling framework make long-term TC-resolving simulations much more feasible.
