Nowadays,we are heading towards integrating hundreds to thousands of cores on a single chip.However,traditional system software and middleware are not well suited to manage and provide services at such large scale.To improve the scalability and adaptability of operating system and middleware services on future many-core platform,we propose the pinned OS/services.By porting each OS and runtime system(middleware) service to a separate core(special hardware acceleration),we expect to achieve maximal performance gain and energy efficiency in many-core environments.As a case study,we target on XML(Extensible Markup Language),the commonly used data transfer/store standard in the world.We have successfully implemented and evaluated the design of porting XML parsing service onto Intel 48-core Single-Chip Cloud Computer(SCC) platform.The results show that it can provide considerable energy saving.However,we also identified heavy performance penalties introduced from memory side,making the parsing service bloated.Hence,as a further step,we propose the memory-side hardware accelerator for XML parsing.With specified hardware design,we can further enhance the performance gain and energy efficiency,where the performance can be improved by 20% with 12.27% energy reduction. 相似文献

为拓展纤维素降解菌资源,以羧甲基纤维素钠(CMC-Na)为唯一碳源作初筛培养基,从浓香型白酒发酵副产物黄水中分离得到18株具有产纤维素酶能力的菌株进行纯培养。形态学、生理生化和系统发育鉴定结果显示,菌株XH01、XH04、XH05、XH18为Bacillus cereus,菌株XH34为Bacillus circulans,菌株SW01、SW05为Bacillus megaterium,菌株SW02为Bacillus endophyticus,菌株SW03、SW04为Bacillus simplex,菌株SW09、SW13为Bacillus bataviensis。菌株ZL08为Penicillium camemberti,菌株ZL13为Aspergillus fumigatus,菌株ZL04和ZL25为Penicillium chrysogenum,菌株ZL15和ZL17为Alternaria tenuissima。利用二硝基水杨酸法对菌株发酵液纤维素酶活进行研究,结果表明,菌株SW02的产酶活性较高,其羧甲基纤维素酶活为153.36 U/mL,β-葡萄糖苷酶活为126.00 U/mL,微晶纤维素酶活为17.64 U/mL,滤纸酶活为30.48 U/mL。 相似文献
