テスト用Linuxクラスタシステムの試作

摘要

Most computer cluster, which is produced by a company, is so expensive compared to a PC, and the versions of its operating system and parallel programming development tools are old. But in most cases, a user cannot install and test the higher version OSs and tools, because most cluster is shared by multiple laboratories or sections inside universities, institutes, or companies, because of its high cost. In addition, a cluster which consists of a lot of computers repuires huge physical spaces, a special construction of the electric power, and suitable air conditioners, and these also repuires additional expensive costs.rnIn this paper, the computer cluster, which consists of multiple KUROBOXes of Kuroutoshikou Inc., called "KUROBOX cluster", is proposed. Its performance is very low, but the cluster is very low cost, very low electric power, and very small physical size, comared to most cluster by a company. We propose this cluster as a tester of parallel computer programs, including operating systems and parallel programming development tools.%商用のクラスタシステムは，高価だがOSや開発環境のバージョンが古いことが多く，また高価ゆえに他の研究室と共用での運用となるため，OSや開発環境のバージョンアップの実施は困難である．さらに，多ノードのシステムは広い物理スペースを占有し，かつ多大な電力が必要なため，特別な電源工事や冷房設備工事などが必要となる．本研究では，玄人志向社製の複数台の「玄箱」から成るクラスタシステムを提案する．このクラスタシステムは，計算能力の観点からは低スペックではあるが，多ノードのシステムを安価で低消費電力，かつ小さい物理サイズで構築できる．これを，新しいバージョンのOSや並列計算環境のテストを含めた並列化プログラムのテスト用のシステムとして提案する．
