1. 以前用OpenGL和DirectX API简介操作GPU,必须了解图形学的知识,直接操作GPU要考虑并发,原子操作等等,cuda架构为此专门设计。满足浮点运算,用裁剪后的指令集执行通用计算,不是仅限于执行图形计算,不仅可以任意读写内存,还可以访问共享内存。提供了许多功能加速计算,设计了CUDA C语言编写通用计算 2. 在GPU上执行的函数...
记得之前说过cudaHostAlloc()函数中最后一个参数是cudaHostAllocDefault,可以分配一个默认的锁页内存。这里介绍另一个参数:cudaHostAllocMapped,它分配的内存仍然是锁页内存。但是,还有一个重要的性质,它分配的内存可以被kernel直接访问。因为这段内存不需要在device与host之间来回拷贝,即零拷贝内存。
