We can pass an array (one-, two- or multidimensional) as an argument to a function. The C language allows us to define functions that have one or more arrays as parameters. These parameters can be of different types and sizes. Moreover, we can mix scalar
In addition, if a function argument is explicitly declared to be a pointer type (such as POINTER(c_int)) in argtypes,an object of the pointed type (c_int in this case) can be passed to the function. ctypes will apply the required byref()conversion in this case automatically. (2)几种...
kernel_name即为上面讲的核函数名称,argument list是核函数的函数入参,在<<<>>>中间,有3个参数: blockDim,规定了核函数将会在几个核上执行,我们可以先设置为1; l2ctrl,保留参数,暂时设置为固定值nullptr,我们不用关注; stream,使用aclrtCreateStream创建,用于多线程调度。 3样例开发讲解 3.1 样例代码结构 |-...
