GPU 专题： wrap 调度，共享内存， barrier 9.并行算法实战： reduce ， scan ，矩阵乘法等 10.存储大规模三维数据的关键：稀疏数据结构 11.物理仿真实战：邻居搜索表实现 pbf 流体求解 12.C++ 在 ZENO 中的工程实践：从 primitive 说起 13.结业典礼：总结所学知识与优秀作业点评 I 硬件要求： 64 位（ 32 位时代过去了） 至少 2 为什么需要模板函数（ template ） • 避免重复写代码。 • 比如，利用重载实现“将一个数乘以 2” 这个 功能，需要： 为什么面向对象在 HPC 不如函数式和元编程香了？ 这个例子要是按传统的面向对象思想，可能是这样： 令 Int, Float, Double 继承 Numeric 接口类并实现 ，其中 multiply(int) 作为虚函数。然后定义： Numeric *twice(Numeric 来还不如重载方便了？ • 别担心， C++ 规定： • 当模板类型参数 T 作为函数参数时，则可 以省略该模板参数。自动根据调用者的参 数判断。 模板函数：特化的重载 • 有时候，一个统一的实现（比如 t * 2 ）满 足不了某些特殊情况。比如 std::string 就 不能用乘法来重复，这时候我们需要用 t + t 来替代，怎么办呢？ • 没关系，只需添加一个 twice(std::string)
