C++ AMP: Detailed perf metrics?

Question

Coming from a CUDA and OpenCL background, where I have used tools like Nvidia Visual Profiler and AMD's profiling utility that show GPU code metrics such as coalesced loads, % of time ALU is busy, % of time fetch unit is stalled etc. Are there ways to collect such detailed metrics from AMP code?

Answer 1

With an AMD-card you still are able to use GPUPerfAPI and capture GPU-counters.

Answer 2

Hi rahul.garg

You can continue to use low level hardware perf tools from each hardware vendor.

For higher level performance analysis, you can use Visual Studio’s Concurrency Visualizer as described in this blog post:

PS Also, since you are coming from that background, in case you haven’t found them please check out our learning guides for CUDA and for OpenCL
