    JAVASCRIPT FUNCTIONS 详解

    JAVASCRIPT FUNCTIONS 本文是@堂主 对《Pro JavaScript with Mootools》一书的第二章函数部分知识点讲解的翻译。 从现在开始,我们将函数(functions) 的概念定义为“执行一个明确的动作并提供一个返回值的独立代码块”。 再次调用这个函数,给它另外2个参数 result = add(5, 20); console.log(result); // 25 JavaScript 是一个将函数作为一等对象(first-class functions

    DAY48:阅读 Atomic Functions

    Atomic Functions An atomic function performs a read-modify-write atomic operation on one 32-bit or 64 Atomic functions do not act as memory fences and do not imply synchronization or ordering constraints for memory operations (see Memory Fence Functions for more details on memory fences). Atomic functions can only be used in device functions.

    自定义HScript Expression Functions

    当我需要使用Expression Functions来写表达式的时候,比如stamp函数,我试图想通过一种通用的理念站在编程的角度来表述如何使用它,而不是依靠惯性记忆来使用它。

    R Programming week 3-Loop functions

    There are some functions which implement looping to make life easier lapply: Loop over a list and evaluate ) rowMeans = apply(x, 1, mean) colSums = apply(x, 2, sum) colMeans = apply(x, 2, mean) The shortcut functions

    DAY40:阅读Memory Fence Functions

    Memory Fence Functions The CUDA programming model assumes a device with a weakly-ordered memory model and B equal to 2, · A equal to 10 and B equal to 2, · A equal to 10 and B equal to 20, Memory fence functions The memory fence functions differ in the scope in which the orderings are enforced but they are independent about atomic functions). Memory fence functions only affect the ordering of memory operations by a thread; they do not ensure

    Warp Vote Functions ? The warp vote functions allow the threads of a given warp to perform a reduction-and-broadcast operation These functions take as input an integer predicate from each thread in the warp and compare those values to be convergent at subsequent instructions unless those instructions are synchronizing warp-builtin functions
