PM/InfiniBand-FJ: A High Performance Communication Facility Using InfiniBand for Large Scale PC Clusters
High Performance Computing and Grid in Asia Pacific Region, International Conference on
By Shinji Sumimoto, Akira Naruse, Kouichi Kumon, Kouji Hosoe, Toshiyuki Shimizu
Issue Date:July 2004
This paper describes a design of high performance communication facility called the PM/InfiniBand-FJ using InfiniBand interconnect for large scale PC clusters. The PM/InfiniBand-FJ has developed to realize higher application performance than commercial sup...
The Tofu Interconnect
By Yuichiro Ajima,Tomohiro Inoue,Shinya Hiramoto,Toshiyuki Shimizu,Yuzo Takagi
Issue Date:January 2012
The Tofu interconnect uses a 6D mesh/torus topology in which each cubic fragment of the network has the embeddability of a 3D torus graph, allowing users to run multiple topology-aware applications. This article describes the Tofu interconnect architecture...
The Tofu Interconnect
High-Performance Interconnects, Symposium on
By Yuichiro Ajima,Yuzo Takagi,Tomohiro Inoue,Shinya Hiramoto,Toshiyuki Shimizu
Issue Date:August 2011
The Tofu interconnect was developed by Fujitsu as a national project of MEXT. The goal of the project is to develop one of the world's most powerful general purpose supercomputer systems and grand challenge applications, and to build a core research hub fo...
Power Reduction Scheme of Fans in a Blade System by Considering the Imbalance of CPU Temperatures
IEEE-ACM International Conference on Green Computing and Communications and International Conference on Cyber, Physical and Social Computing
By Yuetsu Kodama, Satoshi Itoh, Toshiyuki Shimizu, Satoshi Sekiguchi, Hiroshi Nakamura, Naohiko Mori
Issue Date:December 2010
In order to develop a data center power efficiency index, we built a test bed of a data center and measured power components and environmental variables in some detail, including the power consumption and temperature of each node, rack and air conditioning...
Tofu: A 6D Mesh/Torus Interconnect for Exascale Computers
By Yuichiro Ajima, Shinji Sumimoto, Toshiyuki Shimizu
Issue Date:November 2009
A new architecture with a six-dimensional mesh/torus topology achieves highly scalable and fault-tolerant interconnection networks for large-scale supercomputers that can exceed 10 petaflops.
Development of an XML Information Retrieval System for Queries on Contents and Structures
Informatics Research for Development of Knowledge Society Infrastructure, International Conference on
By Toshiyuki Shimizu, Norimasa Terada, Masatoshi Yoshikawa
Issue Date:January 2007
We have developed an XML information retrieval system which can process queries by keywords or queries by combination of keywords and structural conditions. Queries by keywords are simple yet useful because users are not required to understand XML query la...
Supporting Keyword Selection in Generating Earth Science Metadata
2013 IEEE 37th Annual Computer Software and Applications Conference (COMPSAC)
By Toshiyuki Shimizu,Tomo Sueki,Masatoshi Yoshikawa
Issue Date:July 2013
Vast amounts of earth science data have been stored and managed in various projects. Because earth science requires considerable experience and expertise, we generally generate metadata for earth science datasets. In such metadata, keyword information is i...
AP1000+: architectural support of PUT/GET interface for parallelizing compiler
Proceedings of the sixth international conference on Architectural support for programming languages and operating systems (ASPLOS-VI)
By Hiroaki Ishihata, Kenichi Hayashi, Nobutaka Imamura, Osamu Shiraki, Takeshi Horie, Tatsuya Shindo, Toshiyuki Shimizu, Tsunehisa Doi, Yoichi Koyanagi
Issue Date:October 1994
The scalability of distributed-memory parallel computers makes them attractive candidates for solving large-scale problems. New languages, such as HPF, FortranD, and VPP Fortran, have been developed to enable existing software to be easily ported to such m...
Improving AP1000 parallel computer performance with message communication
Proceedings of the 20th annual international symposium on Computer architecture (ISCA '93)
By Hiroaki Ishihata, Kenichi Hayashi, Takeshi Horie, Toshiyuki Shimizu
Issue Date:May 1993
The performance of message-passing applications depends on cpu speed, communication throughput and latency, and message handling overhead. In this paper we investigate the effect of varying these parameters and applying techniques to reduce message handlin...
Low-latency message communication support for the AP1000
Proceedings of the 19th annual international symposium on Computer architecture (ISCA '92)
By Hiroaki Ishihata, Takeshi Horie, Toshiyuki Shimizu
Issue Date:May 1992
Low-latency communication is the key to achieving a high-performance parallel computer. In using state-of-the-art processors, we must take cache memory into account. This paper presents an architecture for low-latency message comunication and implementatio...
Design and implementation of PVFS-PM: a cluster file system on SCore
Cluster Computing and the Grid, IEEE International Symposium on
By Koji SEGAWA, Osamu TATEBE, Yuetsu KODAMA, Tomohiro KUDOH, Toshiyuki SHIMIZU
Issue Date:May 2003
This paper discusses the design and implementation of a cluster file system, called PVFS-PM, on the SCore cluster system software. This is the first attempt to implement a cluster file system on the SCore system. It is based on the PVFS cluster file system...
