However, a setting cost of a virtual cluster is very large and a processing ability of a virtual cluster is lower than that of a cluster without virtualization (no-virtual cluster). In this paper, we introduce how to construct a virtual cluster simply by using virtualization software \"Xen\" and cluster auto-setup tool \"DCAST\". We also draw a comparison by using HPL benchmark between a virtual cluster and a no-virtual cluster. The result shows that the performance of a virtual cluster is about 1.1% on 1 process and about 11.9 % on 32 processes lower than that of no-virtual cluster. Moreover, we evaluate a network performance by using Netperf benchmark. The result shows that the performance of Request/Response ability of a virtual cluster is about twice as low as that of no-virtual cluster. In conclusion, a parallel application where there is no frequent network communication can be performed on a virtual cluster. On the other hand, a parallel application which needs frequent communication cannot be performed on a virtual cluster.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000012062","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学理工学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Science
