In the past five years, research ongrid technology has been thriving and grid technology has been widely adopted by a number of government organiza-tions and research institutions to establish their own large-scale resource sharing network. This paper presents a re-view of recent research on elemental grid technology. We focus on a brief overview on Grid's protocol architecture. Inthe end, we list a series of large projects to illustrate the current application situation based on the ongoing grid tech-nology and preview the tendency of grid technology in the future.展开更多
Windows CE是一种典型的嵌入式系统,由于其配置的硬件资源的瓶颈,内存资源比一般的PC相对紧张。所以在安装Windows CE的设备下显示大像素图像文件比在一般的PC(Windows2000系统)上更加困难。介绍在Windows CE环境下如何利用分块显示法,...Windows CE是一种典型的嵌入式系统,由于其配置的硬件资源的瓶颈,内存资源比一般的PC相对紧张。所以在安装Windows CE的设备下显示大像素图像文件比在一般的PC(Windows2000系统)上更加困难。介绍在Windows CE环境下如何利用分块显示法,对大像素图像进行分块显示。提出首先在PC机上利用网格分块法将一幅大像素图像文件BMP,JPEG图像文件分割压缩成多块像素量小的BMP,JPEG图像文件,对每个小图像文件进行编号,存放到Windows CE PDA上;然后在Windows CE PDA上利用网格检索的方法进行检索所需要的像素块的索引号;最后利用多线程的方法在显示区分块显示,实现大像素图像在Windows CE下的显示。展开更多
