 note = {Multicore processing has become a major trend in high-performance computing. However, there are two major issues with multicore technologies: 1) how to make full use of modern multicore CPU capability with reduced user workload, and 2) how to achieve better scalability up to a high degree of parallelism for memory-intensive applications such as computational fluid dynamics. First, the multicore-based massively parallel cluster of the Japan Aerospace Exploration Agency (JAXA) supercomputer system, which uses the Fujitsu FX1 as the core computer, is described. Notable features such as a high-speed barrier network, enhanced memory bandwidth, and an integrated mechanism to hide latency, i.e., the integrated multicore parallel architecture, which comprises a hardware barrier, L2 cache shared among cores, and an associated automated parallelization complier, are described. Second, the process to achieve significantly high sustained performance (>90%, high-performance Linpack benchmark) on the multicore CPU cluster system is explained. Finally, performance measurement results for JAXA applications are provided., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530011000, レポート番号: JAXA-RM-14-011E},
