Technology NVIDIA CUDA ™ - is the only development environment for C, which allows programmers and developers to write software to solve complex computational problems in less time thanks to the multi-core processing power of GPUs. The world has installed millions of GPU with support for CUDA, and thousands of programmers have free use CUDA tools to accelerate applications - from video and audio encoding to oil and gas exploration, simulation products, the withdrawal of medical imaging and research.

This latest release supports several significant new features that deliver a major leap forward in getting the most performance out of NVIDIA’s massively parallel CUDA-enabled GPUs. This release of the CUDA Toolkit includes performance improvements and expanded support for the cuda-gdb hardware debugger.

Additional new features in CUDA Toolkit 2.3 include:
* The CUFFT Library now supports double-precision transforms and includes significant performance improvements for single-precision transforms as well. See the CUDA Toolkit release notes for details.
* The CUDA-GDB hardware debugger and CUDA Visual Profiler are now included in the CUDA Toolkit installer, and the CUDA-GDB debugger is now available for all supported Linux distros. (see below)
* Each GPU in an SLI group is now enumerated individually, so compute applications can now take advantage of multi-GPU performance even when SLI is enabled for graphics.
* The 64-bit versions of the CUDA Toolkit now support compiling 32-bit applications. (see the release notes for details, including changes to LD_LIBRARY_PATH on Linux)
* New support for fp16 fp32 conversion intrinsics allows storage of data in fp16 format with computation in fp32. Use of fp16 format is ideal for applications that require higher numerical range than 16-bit integer but less precision than fp32 and reduces memory space and bandwidth consumption.

The CUDA SDK has been updated to include:
* A new pitchLinearTexure code sample that shows how to efficiently texture from pitch linear memory.
* A new PTXJIT code sample illustrating how to use cuModuleLoadDataEx() to load PTX source from memory instead of loading a file.
* Two new code samples for Windows, showing how to use the NVCUVID library to decode MPEG-2, VC-1, and H.264 content and pass frames to OpenGL or Direct3D for display.
* Updated code samples showing how to properly align CUDA kernel function parameters so the same code works on both x32 and x64 systems.

The Visual Profiler includes several enhancements:
* All memory transfer API calls are now reported
* Support for profiling multiple contexts per GPU
* Synchronized clocks for requested start time on the CPU and start/end times on the GPU for all kernel launches and memory transfers
* Global memory load and store efficiency metrics for GPUs with compute capability 1.2 and higher.
