Reconfigurable Computing Cluster

Sass Ron, Schmidt Andrew G., Scott Buscemi · Advances in parallel computing · 2012

The Reconfigurable Computing Cluster project has been investigating broad question of what, if any, role FPGAs may play in parallel computing. While this article does not answer that question but describes the experiences thus far. The main vehicle for research has been Spirit, a small-scale experimental machine consisting of 64 FPGAs connected in 3-D torus. It has been at the core of several focused studies. This article provides a summary of the architecture, the scientific and pragmatic discoveries enabled by the machine, and two more FPGA-based parallel computers that are presently under development.

GenProg Meets Cluster Computing

Junnosuke Matsumoto, Yoshiki Higo, Hiroyuki Matsuo et al. · 2019

GenProg is an automated program repair tool that leverages genetic algorithm. In the repairing process of GenProg, a larger number of mutated programs are generated, built, and tested. If none of mutated programs passes all the test cases, GenProg redos the loop of generation, build and test. The build and test occupy over 90% of GenProg's execution. In this paper, we introduce our cluster-based GenProg, which builds and tests in parallel with many computers. We have implemented the cluster-based GenProg with Kubernetes environment and applied it to real bugs in Defects4J dataset. As a result, we confirmed that the time required for program repair is reduced according to the number of computers in the cluster.

Abstract Transactional Cluster Computing

Stefan Frenz, Michael Schoettner, Ralph Goeckelmann et al. · 2008

A lot of sophisticated techniques and platforms have been proposed to build distributed object systems. Remote method invocation and explicit message passing on top of traditional operating systems are complex and difficult to program. As an alternative the distributed memory idea simplifies and unifies memory access, but performance drawbacks caused by expensive distributed locking mechanisms obviated this approach for cluster computing. To avoid these slowdowns more and more weak consistency models try to avoid these slowdowns by burdening the programmer with explicit synchronization. Our research group has developed a fast transaction system for a distributed heap that guarantees semantically correct access to shared memory.

Multichip quantum computing cluster

Королев, А. В., Андреенко, А. В., Кривошеева, А. В. et al. · Репозиторий БГУИР (BSUIR Repository) · 2007

Предложена компоновка многокристального квантового вычислительного модуля на ансамблевых кубитах с использованием постоянного V-образного магнита. Дана оценка критериев разделения резонансных частот и измеримости состояний ансамблевых кубит на основе квантовых шнуров индия. Показано, что магнитное поле, создаваемое V-образным постоянным магнитом, лежит в диапазоне 104–105 А/м и имеет градиент порядка 4⋅1010 А/м2, что достаточно для организации квантовых вычислений.

Cluster State Quantum Computing

Paul M. Alsing, Michael L. Fanto, A. Matthew Smith · 2012

Abstract : Experimental, theoretical and numerical investigations of quantum computation using photon-based qubits were conducted to explore the Cluster State (or one-way) Quantum Computing paradigm. This report describes research on a unique type II SPDC source (Schioedtei) design that can generate up to six pairs of entangled photons per pass through the type II crystal assembly. This source is currently being used as the entangled photon source to create photon-based qubit cluster states. Under this project we developed a new detector design architecture that turns the single photon detector into a number-resolving detector by means of a novel three dimensional architecture that utilizes spatial multiplexing. We have studied the CNOT gate, as an archetypical quantum linear optical gate, and found several interesting features in the both the ideal and the realistic case of implementation with imperfect (non-unit) fidelity. We have conducted a theoretical investigation of the limitations of quantum correlations under the physically imposed constraint of no-signaling (no faster than light communication). We discuss our ongoing work of quantum algorithm development.

Distributed Cluster Computing Environments

Mark Baker, Geoffrey Fox · 1996

This report aims to catalogue and briefly describe Distributed Cluster Computing Environments (DCCE) as well as newly established Cluster Management Software (CMS) projects. The document started out as part of a review commissioned by the UK government on Cluster Computing [1], and followed two other reports: a historic review of Cluster Computing produced by the Manchester Computing Centre [2], and a critical review of Cluster Computing projects funded by the NTSC [3] and produced by the University of Southampton. Whilst gathering the information to produce the Cluster Computing Review it became evident that software for cluster computing fell into one of two camps: 1. Cluster Management Software (CMS) - this software is designed to administer and manage application jobs submitted to workstation clusters. It encompasses the traditional batch and queuing systems. 2. Distributed Cluster Computing Environments (DCCE) - with this software the cluster is typically used as an applications environment, similar in many ways to distributed shared memory systems. This chapter also includes descriptions of environments which are at an early stage of development stage. This document deals with 2), the CMS is now reviewed in [4]

Cluster and Grid Computing

Hai Jin, Li Qi, Song Wu et al. · 2012

Any mistaken maintenance for the complicated and distributed grid can bring unpredictable disaster. Here we focus on the system availability issues caused by service dependencies during the maintenance in grid. A novel mechanism, called Cobweb Guardian, is proposed in this paper. It provides multiple granularities (service-, container-, and node-level) maintenance for service components in grid. By using the Cobweb Guardian, grid administrators can execute the maintaining task safely in runtime with high availability. The evaluation results show that our proposed dependency-aware maintenance can make the grid management more automatic and available. 1.

Cluster Computing with iMacs

Power Macintoshes, D. A. Grove, P. D. Coddington et al. · 1999

We investigate the use of a cluster of networked Apple iMac or Power Macintosh personal computers as a compute server for sequential and parallel programs, and describe our experiences with a cluster of iMacs used primarily for an undergraduate teaching laboratory. We explore the support for cluster computing offered by the various operating systems available for the Macintosh: MacOS 8; the upcoming MacOS X which offers Unix functionality; and the recently available LinuxPPC for the Macintosh. We present sequential and parallel benchmark performance results for an iMac cluster, a Beowulf-style Intel Pentium PC cluster, and a network of DEC Alpha workstations. We compare the performance and price/performance of these systems, and discuss some of the less quantifiable issues such as software installation, ease of use, and system maintenance.
