CUDA Toolkit

The NVIDIA® CUDA® Toolkit provides a comprehensive development environment for C and C++ developers building GPU-accelerated applications. The CUDA Toolkit includes a compiler for NVIDIA GPUs, math libraries, and tools for debugging and optimizing the performance of your applications. You’ll also find programming guides, user manuals, API reference, and other documentation to help you get started quickly accelerating your application with GPUs.

Dramatically simplify parallel programming with CUDA 6

Unified Memory
  • Simplifies programming by enabling applications to access CPU and GPU memory without the need to manually copy data. Read more about unified memory.
Drop-in Libraries
  • Automatically accelerate applications’ BLAS and FFTW calculations by up to 8X by simply replacing the existing CPU libraries with the GPU-accelerated equivalents.
Multi-GPU scaling
  • cublasXT - a new BLAS GPU library that automatically scales performance across up to eight GPUs in a single node, delivering over nine teraflops of double precision performance per node, and supporting larger workloads than ever before (up to 512GB). The re-designed FFT GPU library scales up to 2 GPUs in a single node, allowing larger transform sizes and higher throughput.
All developers can now download the CUDA 6  today. Become a CUDA Registered Developer to report any issues.
