Exercise: Accelerating a For Loop with Multiple Blocks of Threads 目前,02-multi-block-loop.cu内的loop函数运行着一个“for 循环”并将连续打印0至9之间的所有数字。将loop函数重构为 CUDA 核函数,使其在启动后并行执行N次迭代。重构成功后,应仍能打印0至9之间的所有数字。对于本练习,作为附加限制,请使用启...
In addition, when using mapped page-locked memory (Mapped Memory), there is no need to allocate any device memory and explicitly copy data between device and host memory. Data transfers are implicitly performed each time the kernel accesses the mapped memory. For maximum performance, these memory...
Q: How can I send suggestions for improvements to the CUDA Toolkit?Become a registered developer, then you can directly use our bug reporting system to make suggestions and requests , in addition to reporting bugs etc.Q: I would like to ask the CUDA Team some questions directly? You can ...

program is executed for each data element, there is a lower requirement for sophisticated flow control【复杂的流控制】, and because it is executed on many data elements and has high arithmetic intensity, the memory access latency【内存访问延迟】 can be hidden with calculations instead of big ...
其中,双重嵌套的for循环的每次迭代都由一个专用的Triton program实例执行。 计算kernel 上述算法实际上在Triton中相当容易实现。主要的难点来自于在内循环中计算必须读取A和B块的内存位置。为此,我们需要多维指针运算。 指针运算 对于一个2D Tensor X,X[i, j]的内存位置为&X[i, j] = X + i*stride_xi + j...

This CUDA Driver API sample uses NVRTC for runtime compilation of vector addition kernel. Vector addition kernel demonstrated is the same as the sample illustrating Chapter 3 of the programming guide. This sample depends on other applications or libraries to be present on the system to either bu...
