Parallel Nsight Box Image

We're pleased to announce that NVIDIA Parallel Nsight 1.0, our GPGPU and graphics development environment integrated into Visual Studio, has been released. Parallel Nsight bring GPGPU and graphics developers an unprecedented amount of power, and supports APIs like CUDA C/C++, OpenCL, DirectCompute, Direct3D, and OpenGL.

Getting the build:
The build is now available from the Parallel Nsight Developer Zone page.
Follow the instructions on the download page to download and then activate your build immediately.



Parallel Nsight Debugger for GPU Computing

  • Debug your CUDA C/C++ and DirectCompute source code directly on the GPU hardware
  • As the industry's only GPU hardware debugging solution, it drastically increases debugging speed and accuracy
  • Use the familiar Visual Studio Locals, Watches, Memory and Breakpoints windows


Parallel Nsight Analyzer for GPU Computing
(Professional version only)

  • Isolate performance bottlenecks by viewing system-wide CPU+GPU events
  • Support for all major GPU Computing APIs, including CUDA C/C++, OpenCL, and Microsoft DirectCompute



Parallel Nsight Debugger for Graphics Development

  • Debug HLSL shaders directly on the GPU hardware. Drastically increasing debugging speed and accuracy over emulated (SW) debugging
  • Use the familiar Visual Studio Locals, Watches, Memory and Breakpoints windows with HLSL shaders, including DirectCompute code
  • The Debugger supports all HLSL shader types: Vertex, Pixel, Geometry, and Tessellation


Parallel Nsight Graphics Inspector for Graphics Development

  • Graphics Inspector captures Direct3D rendered frames for real-time examination
  • The Frame Profiler automatically identifies bottlenecks and performance information on a per-draw call basis
  • Pixel History shows you all operations that affected a given pixel

NVIDIA is proud to announce the immediate availability of OpenGL 4 drivers for Linux as well as OpenGL 4 WHQL-certified drivers for Windows. Additionally, support for eight new extensions is provided:

  • ARB_texture_compression_bptc – provides additional texture compression functionality specific to the BPTC and BPTC_FLOAT compressed texture formats (called BC7 and BC6H respectively in DirectX 11)
  • EXT_shader_image_load_store - provides GLSL built-in functions allowing shaders to load from, store to, and perform atomic read-modify-write operations to a texture object.
  • EXT_vertex_attrib_64bit - provides OpenGL shading language support for vertex shader inputs with 64-bit floating-point components and OpenGL API support for specifying the value of those inputs.
  • NV_vertex_attrib_integer_64bit - provides support for specifying vertex attributes with 64-bit integer components, analogous to the 64-bit floating point support added in EXT_vertex_attrib_64bit.
  • NV_gpu_program5 - documents the common instruction set and basic functionality provided by NVIDIA's 5th generation of assembly instruction sets supporting programmable graphics pipeline stages.
  • NV_tesssellation_program5 - provides assembly programmable shaders for performing tessellation.
  • NV_gpu_shader5 - provides a superset of the features provided in ARB_gpu_shader5. This includes support for a full set of 8-, 16-, 32-, and 64-bit scalar and vector data types, and more. Additionally, it allows patches (created in the tessellation stage) to be passed on to the geometry shader, used as input to transform feedback, and even passed to fixed-function rasterization.
  • NV_shader_buffer_store – lifts the restriction from the Bindless Graphics extension NV_shader_buffer_load that disallows writes to buffer objects. The shading language is extended to allow shaders to write through (GPU address) pointers. Additionally, the extension provides built-in functions to perform atomic memory transactions to buffer object memory.
