 note = {Exa FLOPS 級スーパーコンピュータの実現には低レイテンシ・省メモリを兼ね備える通信プロトコルの開発が不可欠である.我々は本課題の解決手段の一つとして Atomic 通信を用いる通信資源の動的管理手法を検討している.本報告書は,通信手順の最適化や性能予測等に役立てるための基礎データの取得を目的に,InfiniBand の Atomic 通信を中心とした性能評価結果を報告する.メモリの不可分性を保つために自ノードメモリに対しても必要に応じて HCA を経由した Atomic Operation が必要であるが,この場合,自ノードのメモリアクセスにおいもてもノード間と同程度の性能しか望めないことが分かった.一方,外乱通信による性能劣化はメモリ書き換えを伴う RDMA Write, Atomic 通信を同時に行うことによって大きくなることが分かった., It is necessary to establish the communication protocol which has both low latency and saving memory to realize the Exa FLOPS supercomputer. We have thought that dynamic resource management by using remote atomic memory access is one of key technologies for the solution. This article reports transportation performance of InfiniBand(IB) including the remote atomic memory operation. The data has taken to be used for optimization and estimation of the communication procedure. We found that the local memory access through IB HCA is expected almost same performance of the inter node remote atomic memory access. Because, the local memory which needs to assure atomicity should be access through the IB HCA. Also, we found that the performance deterioration is depending on combination of transfer functions. The combination of transfer functions which consists writing the memory like RDMA Write and Atomic operation brings large deterioration.},
