CudaPAD is a PTX/SASS viewer for NVIDIA Cuda kernels
Introduction
CudaPAD is software that aids in the optimizing and understanding of NVidia’s Cuda kernels by displaying an on-the-fly view of the PTX/SASS that makes up the GPU kernel. CudaPAD simply shows the PTX/SASS output, however it has several visual aids to help understand how minor code tweaks or compiler options can affect the PTX/SASS.
What is PTX or SASS anyway? NVidia’s PTX is an intermediate language for NVidia GPU’s. It is closely tied to pure GPU assembly(SASS) but is slightly abstracted. PTX less tied to a specific hardware or generation which makes it more useful in some cases. It also somewhat abstracts register usage which makes it a little bit easier to use. PTX instructions are usually translated into one or more actual hardware instructions. SASS on the other-hand is hardcore assembly. It is what the GPU actually runs and is directly translated into machine code. Viewing SASS code is more difficult but it d
