《CUDA by Example》--chapter10 code 先来介绍CUDA中的一个函数:cudaHostAlloc(),理解这个函数,要和标准C语言中的()联系起来。malloc()函数是CPU在主存中开辟内存并返回指针,而cudaHostAlloc()是cuda在主存中开辟指定内存并返回指针。cuda开辟和CPU开辟的主存有什么不同?CPU是分配可分页的(Pagable)主机内存,而cu...

使用指定目标体系结构的编译器选项-code生成cubin对象:例如,使用-code=sm_35编译会为计算能力为 3.5 的设备生成二进制代码。 从一个次要修订版到下一个修订版都保证了二进制兼容性,但不能保证从一个次要修订版到前一个修订版或跨主要修订版。 换句话说,为计算能力 X.y 生成的 cubin 对象只会在计算能力 X.z...
