我々は,Gigabit Ethernetを用いたクラスタシステム上で並列アプリケーショ ンを実行することを目的とした高速通信機構(GigaE PM)を開発している. GigaE PMは,信頼性を確保した高バンド幅,低遅延通信を実現し,かつ,同 時にTCP/IPなどの既存の標準プロトコルもサポートしている.GigaE PMでは, クラスタシステム向けプロトコル処理はNIC上のファームウェアで,既存の 通信プロトコル処理は従来どおりカーネルで処理する.プロトタイプシステム をEssential社NICに実装し評価した結果,Pentium II 400 MHz PC上で48.3usのラウンドトリップ遅延(4バイトメッセージ)と,56.7MBのバン ド幅(1 468バイトメッセージ)を実現している.さらにGigaE PM上にMPI通 信ライブラリを構築し,GigaE PMとTCP/IP上のMPI通信ライブラリを用いた ベンチマーク評価を行っている.NAS並列ベンチマークIS(クラスS)の評価 では,GigaE PMの結果はTCP/IPの結果に比べ,1.8倍の性能向上を得ている.A high performance communication facility, called the GigaE PM, has been designed and implemented for parallel applications on cluster systems using a Gigabit Ethernet. The GigaE PM provides not only a reliable high bandwidth and low latency communication, but also supports existing network protocols such as TCP/IP. In the design of the GigaE PM, a reliable communication protocol for a parallel application is implemented on the firmware of network interface card while existing network protocols are handled by an operating system kernel. A prototype system has been implemented using an Essential Communications Gigabit Ethernet card, and evaluated its performance. The performance results show that a 48.3us round trip time for a four byte message, and 56.7MB/sec bandwidth for a 1,468byte message have been achieved on Intel Pentium II 400MHz PCs. We have implemented MPICH-PM on the top of GigaE PM, and evaluated the performance using NAS parallel benchmarks. The results show that the IS (class S) performance on GigaE PM is 1.8 times faster than that of on TCP/IP.
