NVIDIA Developer Forums
and the
GPU Computing Forums
require separate logins. We will fix this in the near future when the two forums are merged. Thank you for your patience!
GPUDirect(tm) gives 3rd party devices direct access to CUDA Memory
Support for 16-way concurrency allows up to 16 different kernels to run at the same time on Fermi architecture GPUs
Runtime / Driver interoperability enables applications to mix-n-match use of the CUDA Driver API with CUDA C Runtim and math libraries via buffer sharing and context migration
New language features added to CUDA C / C++ include:
Support for printf() in device code
Support for function pointers and recursion make it easier to port many existing algorithms to Fermi GPUs
Unified Visual Profiler now supports both CUDA C/C++ and OpenCL, and now includes support for CUDA Driver API tracing
Math Libraries Performance Improvements, including:
Improved performance of selected transcendental functions from the log, pow, erf, and gamma families
Significant improvements in double-precision FFT performance on Fermi-architecture GPUs for 2^n transform sizes
Streaming API now supported in CUBLAS for overlapping copy and compute operations
CUFFT Real-to-complex (R2C) and complex-to-real (C2R) optimizations for 2^n data sizes
Improved performance for GEMV and SYMV subroutines in CUBLAS
Optimized double-precision implementations of divide and reciprocal routines for the Fermi architecture
New and updated SDK code samples demonstrating how to use:
Function pointers in CUDA C/C++ kernels
OpenCL / Direct3D buffer sharing
Hidden Markov Model in OpenCL
Microsoft Excel GPGPU example showing how to run an Excel function on the GPU
Windows developers should be sure to check out the new debugging and profiling features in Parallel Nsight for Visual Studio
at www.nvidia.com/nsight.
Please refer to the release notes and Getting Started Guides for more information.
