Nsight Visual Studio Edition CUDA Debugger Key Features

• Debug your CUDA C/C++ source code directly on the latest GPU hardware
• Debug native Visual Studio CPU and CUDA GPU code within the same debugging session
• Use the familiar Visual Studio Locals, Watches, Memory and Breakpoints windows
• Inspect the CUDA kernel state using customs views for GPU registers, warps, lanes, and threads for navigating massively parallel threads states and contexts

Nsight Visual Studio Edition CUDA Debugger Watch Window

• View Source variables, PTX & SASS registers in Locals & Watch Views
• Expressions supported in Watch view
• Updated variables are displayed with red font
• Struct/Vector/Array contents display on a single line
• Array max length settings
• Error messages for out-of-scope or invalid expressions

Nsight Visual Studio Edition CUDA Debugger Source Code View

• View correlated Source, PTX, and SASS
• Set breakpoints in Source and/or SASS
• Step over, in, out, continue in source or PTX/SASS disassembly
• Conditional breakpoints operate on source vars and PTX/SASS regs
• Hover over variables and registers to view values

Nsight Visual Studio Edition CUDA Debugger Breakpoints View

• Supported Breakpoints for Native(CPU) and CUDA C/C++ code, including
  Source, SASS, Function, Conditional, Data
• Full GPU and CPU State provided while at breakpoint
• Process and Thread selection available
• Conditional breakpoints operate on source vars and PTX/SASS regs

Nsight Visual Studio Edition CUDA Debugger Warp Info View

• Warp Info shows the active warps on the GPU, one warp per row
• Arrow indicates the in-focus thread, providing state for the rest of the views
• Focus warp (row) or thread can be changed with a mouse click to provide further state inspection (unless warp is unlaunched/done)
• Various ‘Freeze Modes’ to for run control of other warps
• Warps are color coded to indicate their state
• Filtering can be done to minimize warp results
• Columns Not shown (PC, ActiveMask, HitMask, Status)

Nsight Visual Studio Edition CUDA Debugger GPU Registers View

• Inspect PTX, SASS, Predicate, Conditional, and Uniform registers at this configurable GPU Register view
• Visual Studio register view can also be configured to show GPU registers
• This view can be configured to hide/show registers sets
• Always hides registers that are not supported by the architecture (Not a Turing GPU, so no Uniform registers shown)
• Can select and copy-to-clipboard
• Red text indicates updated values

NVIDIA Nsight Integration (highlighted) under the Nsight menu

NVIDIA Nsight Developer Tools Integration for Visual Studio

In Nsight VSE 2020.1.1, the integrated Graphics Frame Debuggers and integrated Profilers have been removed, but don't worry, you haven't lost this functionality.
NVIDIA Nsight Integration is a Visual Studio extension that allows you to access the power of the following NVIDIA Nsight standalone tools from within Visual Studio.

• Nsight Compute : CUDA application interactive kernel profiler
• Nsight Graphics : Graphics application frame debugger and profiler
• Nsight Systems : System-wide performance analysis tool

When any of these tools are installed along withNVIDIA Nsight Integration, these tools will appear under the NVIDIA 'Nsight' menu in the Visual Studio menu bar.
