數(shù)據(jù)網(wǎng)格中基于優(yōu)化機(jī)制的通信模型

針對(duì)基于多計(jì)算機(jī)機(jī)群構(gòu)成的網(wǎng)格的大規(guī)模并行計(jì)算的需要，對(duì)多級(jí)分組通信模型的單一機(jī)群分組通信進(jìn)行了研究。探討了在單一機(jī)群內(nèi)的主動(dòng)節(jié)點(diǎn)、被動(dòng)節(jié)點(diǎn)個(gè)數(shù)和各個(gè)計(jì)算節(jié)點(diǎn)的能力以及機(jī)群網(wǎng)絡(luò)的帶寬之間的形式化關(guān)系，優(yōu)化了通信結(jié)構(gòu),描述了基于能力優(yōu)化機(jī)制的通信模型。理論和試驗(yàn)表明，該模型充分利用了機(jī)群的計(jì)算節(jié)點(diǎn)能力、網(wǎng)絡(luò)通信能力。該模型適合基于網(wǎng)格的并行計(jì)算。

Abstract: For the need of large scale parallel computing based on Data Grid that is composed of the multi-clusters, the single cluster grouping communication model for multi-level grouping communication has been researched. The formalized relations among the numbers of active computing nodes and passive computing nodes, the computation capacity of individual computing nodes and the network’s bandwidths within a single cluster have been discussed. The grouping communication model has been described. Both theory and
experiment results show that this model have fully utilized the communication and computation capacity of computing nodes and network. It can be fit for large scale parallel computing in grid.
Key words: data grid; grouping communication; parallel computing
