BCL-3:A High Performance Basic Communication Protocol for Commodity Superserver DAWNING-3000 总被引:3,自引:0,他引:3 下载免费PDF全文
1 IntroductionC1usters have been popu1ar platforms fOr high performance computing in receot years. They arewidely used in scientific and engineering computing business computing, and Internet informationservices. Communication perfOrmance is one of the most critical factors determining the perfOrmanceof a whole cluster system. So how to improve the performance of communication is a hot researchtopic in cluster computing. Meanwhile, bui1ding a cluster with commodity SMPs (CLUMPS) isbecorn… 相似文献

Amorphous Ni-Pd-Si ribbons were partially crystallized by by relaxation treatment thensecondary amorphous Ni-Pd-Si alloy powder was prepared by mechanical milling.Thesurface states of amorphous and crystalline Ni-Pd-Si powders were studied by XRD,TEM,AES and ESCA spectra.The catalytic activities of amorphous and crystalline powders in hydrogenation of styrene was measured.The result shows that the catalytic activityof amorphous Ni—Pd—Si powder was higher than that of crystalline one by 6 times inhydrogenation of styrene. 相似文献
