1太湖之光上利用OpenACC移植和优化GTC-P显示文摘神威'太湖之光'是最新一期Top500榜单上排名第一的超级计算机,实测峰值性能约93PFLOPS.该系统提供了基于指导语句的并行编程工具OpenACC,兼容OpenACC 2.0编程标准,并添加了部分定制化功能.GTC-P是一个具有重要物理意义的科学应用,算法基于高性能计算领域中被广泛使用的PIC(particle-in-cell)方法.利用神威OpenACC并行编程模型在'太湖之光'上成功移植了GTC-P应用.在移植过程中,鉴于OpenACC编译器尚无法解决的性能瓶颈,提出了3种基于中间代码二次开发的优化方法:1)消除原子操作;2)避免低效的全局访存操作;3)手动添加SIMD intrinsics指令.实验结果表明,在64个从核上相比1个主核,优化后的函数charge和push分别实现了1.6倍和8.6倍的加速比,同时GTC-P代码整体取得了2.5倍的加速比.优化结果证明了基于中间代码的手动优化对利用神威OpenACC移植的PIC算法在'太湖之光'上的性能提升非常重要.王一超 林新华 蔡林金 Tang William Ethier Stephane 王蓓 施忠伟 松岗聪 2018计算机研究与发展2018,55,4:8
2人眼视神经乳头星形胶质细胞体外培养:Ⅰ.原代培养和传代试验(英文)显示文摘目的:探索人眼视神经乳头星形胶质细胞体外培养的方法,为进一步研究星形胶质细胞在青光眼性视神经病变中的作用打下基础。方法:取材新鲜人眼视神经乳头组织和筛板组织,进行星形胶质细胞和筛板细胞的体外培养与传代试验。结果:组织块培养4~8wk后,原代细胞开始生长,星形胶质细胞在形态学和生长特性上与筛板细胞明显不同,β1型星形胶质细胞可以在无血清的培养液中生长良好,通过无血清培养液选择性培养可以在第二代传代过程中分离出纯化的星形胶质细胞,并可在第三至第四代收获大量细胞以备后续的研究。结论:精细准确的组织解剖分离对于获得纯化细胞至关重要,采用无血清培养液选择分离获得星形胶质细胞方法经济简单,细胞纯度高,便于进一步储存和研究。戴惟葭 Shelley Culp-Stewwart John Flana-gan C Ross Ethier 2008国际眼科杂志2008,8,7:2
