Visual Studio Code Cuda

There are many CUDA code samples included as part of the CUDA Toolkit to help you get started on the path of writing software with CUDA C/C++

The code samples covers a wide range of applications and techniques, including:

Simple techniques demonstrating
- Basic approaches to GPU Computing
- Best practices for the most important features
- Working efficiently with custom data types
- Quickly integrating GPU acceleration into C and C++ applications
How-To examples covering topics such as:
- Adding support for GPU-accelerated libraries to an application
- Using features such as Zero-Copy Memory, Asynchronous Data Transfers, Unified Virtual Addressing, Peer-to-Peer Communication, Concurrent Kernels, and more
- Sharing data between CUDA and Direct3D/OpenGL graphics APIs (interoperability)

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)

Visual Studio Compile Cuda Code

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 Developer Tools Integration for Visual Studio

In Nsight VSE 2021.1, 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 with NVIDIA Nsight Integration, these tools will appear under the NVIDIA 'Nsight' menu in the Visual Studio menu bar.
