CudaPAD is a simple app that displays a kernel PTX, SASS, and usage information. In a nutshell, it compiles the kernel in the left windows each time it is modified and then posts the PTX in the right window with some visual cues. In the background it is calling nvcc.exe and then showing the information. It has Diff information and as well as usage information.
It’s only for viewing PTX/SASS and does not run any kernels.
Requirements: Visual Studio and Cuda 6.5/7.0
