3.2.6.6.2利用API创建图 可以通过两种机制创建图:显式 API 和流捕获。 以下是创建和执行下图的示例。 // Create the graph - it starts out empty cudaGraphCreate(&graph, 0); // For the purpose of this example, we'll create // the nodes separately from the dependencies to ...
在这个示例中,我们使用CUDA编写了一个核函数multiplyByTwo,该函数将输入数组的每个元素乘以2,并将结果存储到输出数组中。然后,我们在主机内存中初始化输入数组,并在设备上分配内存用于输入和输出数组。接下来,我们使用cudaMemcpy函数将输入数组从主机内存复制到设备内存,然后启动核函数在设备上进行并行计算。最后,我们使用...
