超级计算机是什么
<p>国防科学技术大学日前研制成功了我国首台千万亿次超级计算机系统“天河一号”。“天河一号”的研制成功，标志着我国超级计算机的自主研制实现了从百万亿次到千万亿次的历史性跨越。</p><p><span word="The">The</span> <span word="National">National</span> <span word="University">University</span> <span word="of">of</span> <span word="Defense">Defense</span> <span word="Technology">Technology</span> <span word="unveiled">unveiled</span> <span word="Thursday">Thursday</span> <span word="China">China</span>'<span word="s">s</span> <span word="fastest">fastest</span> <span word="supercomputer">supercomputer</span>, <span word="which">which</span> <span word="is">is</span> <span word="able">able</span> <span word="to">to</span> <span word="do">do</span> <span word="more">more</span> <span word="than">than</span> <span word="one">one</span> <span word="quadrillion">quadrillion</span> <span word="calculations">calculations</span> <span word="per">per</span> <span word="second">second</span> <span word="theoretically">theoretically</span> <span word="at">at</span> <span word="its">its</span> <span word="peak">peak</span> <span word="speed">speed</span>.</p><p>国防科技大学于本周四推出了中国运算速度最快的超级计算机。从理论上讲，这台计算机的运行峰值速度可达每秒千万亿次以上。</p><p>文中的<span word="supercomputer">supercomputer</span>就是指“超级计算机”。<span word="Supercomputer">Supercomputer</span>通常是指由数百数千甚至更多的处理器(机)组成的、能计算普通<span word="PC">PC</span>机和服务器不能完成的大型复杂课题的计算机。假设把普通计算机的运算速度比做成人的走路速度，那么超级计算机就达到了火箭的速度。</p><p>与<span word="supercomputer">supercomputer</span>相对应的则是<span word="minicomputer">minicomputer</span>，也就是我们所说的<span word="PC">PC</span>。家庭中，<span word="computer">computer</span>-<span word="literate">literate</span>(会使用电脑的)孩子们常使用<span word="desktop">desktop</span> <span word="computer">computer</span>(台式机)来玩儿<span word="computer">computer</span> <span word="game">game</span>(电脑游戏)。如果外出使用，还是拿个<span word="laptop">laptop</span>(手提电脑)比较方便。但如果你的电脑中毒了，被<span word="hacker">hacker</span>(黑客)远程操纵，那就变成<span word="zombie">zombie</span> <span word="computer">computer</span>(僵尸电脑)了。</p>
