错误是在的 GPU 执行期间生成的randomSpikeKernelFinal,但由于您没有在调用之间同步主机和设备,因此主机线程能够对内核和memcpy立即执行,而无需等待第一个 CUDA 内核完成。直到流同步之后, CPU 才检测到并报告错误。 由于您有两种不同类型的错误,因此可以分别捕获和清除每一种错误。否则,您只报告您观察到的每种类型...

请问在cuda的核函数中可以按地址调用普通变量么?...如果错误的在本次kernel启动的本block中的其他线程使用,则自动得到被替换成对应的线程的对应local memory位置的值。...(3)最终指向shared memory的指针,仅在本次kernel启动的本block中的任意一个线程中有效。...另外两点需要注意的: (4)在部分平台支持P2P A...
