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.

New in CUDA 7.5

16-bit floating point (FP16) data format
  • Store up to 2x larger datasets in GPU memory
  • Reduce memory bandwidth requirements by up to 2x
  • New mixed precision cublasSgemmEX() routine supports 2x larger matrices
New cuSPARSE GEMVI routines
  • Optimized dense matrix x sparse vector routines - ideal for Natural Language Processing
Instruction-level profiling helps pinpoint performance bottlenecks
  • Quickly identify the specific lines of source code limiting the performance of GPU code
  • Apply advanced performance optimizations more easily

The CUDA Toolkit is now available for all developers.
