I do love the restrict keyword (and const, despite being told in a previous life that you didn't really need the const keyword). The Restrict Contract is an amusing way of putting down what the keyword means. A revised version was on my door for a while:http://cellperformance.beyo.....

● __restrict__ nvcc 支持的关键字。 ■ 在程序员保证输入变量地址不重叠的情况下,可以提示编译器使用优化。减少内存访问次数和计算步数,但有可能增加需要的寄存器数量,造成负优化(CUDA 寄存器压力问题)。 1__device__voidfunc(constfloat* __restrict__ a,constfloat* __restrict__ b,float* __restrict__ ...
