如果问我工作十多年后相比刚毕业参加的时候,学到了哪些重要的经验,那么"Make it work, make it right, make it fast"一定是其中最重要的经验之一.第一次听到这句话是从以前老板 @沈嵘 那里,然后发现是来源自大牛 Kent Beck <Make It Work Make It Right Make It Fast>.这是软件项目开发的一条经典原则,实际上不限于软件开发领域,它把一个项目分成三个阶段,每个阶段有不同的侧重. Make it w…

作者:王博文 | 旷视 MegEngine 架构师 一.背景 对于深度学习框架来说,网络的训练/推理时间是用户非常看中的.在实际生产条件下,用户设计的 NN 网络是千差万别,即使是同一类数学计算,参数也各不相同.如果没有针对性的优化,框架就完全丧失竞争力.因此,在一类数学计算中,开发者们会开发多种高效的算法,分别适用于不同的参数,以保证网络的性能.接下来开发者们需要解决一个新问题,当计算参数确定以后,如何让最快的算法执行该计算. 大部分框架靠先验的经验选择算法,MegEngine 亦总结有优秀的…

自从8月3日跑了半马以后,又一鼓作气报了11月份的西昌马拉松.与第一次马拉松的只求完赛目标不同,第二次当然想取得一个更好的成绩.所以8月份练的比较猛,基本上是练2.3天休息一天,周么还要拉个长于21公里的LSD.拒不完全统计,8月份总跑量达到了260公里+.并且有一天周末跑了个人最好的半马成绩1小时53分. 后来从往网上看到在9月20日布里斯班的一个海滨会举行半程马拉松,叫做Twilight Bay Run(黄昏海滨马拉松),听名字就觉得爽.看了看地图,是在一个海边跑的,沿着海边,吹着海风,痛痛…

run()与异常 不管是Threade还是Runnable的run()方法都没有定义抛出异常,也就是说一条线程内部发生的checked异常,必须也只能在内部用try-catch处理掉,不能往外抛,因为线程是一个独立运行的代码片段,它的问题不能影响到其他线程 如果run()内部抛出一个unchecked异常,这个线程可能会终止运行,这个异常也不能被主线程捕获,也影响不到其他线程的执行,比如下面的示例: package testpack; import java.io.IOException; pu…
