CUDA 6, Available as Free Download, Makes Parallel Programming Easier, FasterWe’re always striving to make parallel programming better, faster and easier for developers creating next-gen scientific, engineering, enterprise and other applications.With the latest release of the CUDA parallel programming model, we’ve made improvements in all these areas.Available now to all developers on the CUDA website, the CUDA 6 Release Candidate is packed with several new features that are sure to please developers.A few highlights: Unified Memory – This major new feature lets CUDA applications access CPU and GPU memory without the need to manually copy data from one to the other. This is a major time saver that simplifies the programming process, and makes it easier for programmers to add GPU acceleration in a wider range of applications. Drop-in Libraries – Want to instantly accelerate your application by up to 8X? The new drop-in libraries can automatically accelerate your BLAS and FFTW calculations by simply replacing the existing CPU-only BLAS or FFTW library with the new, GPU-accelerated equivalent. Multi-GPU Scaling – Re-designed BLAS and FFT GPU libraries automatically scale performance across up to eight GPUs in a single node. This provides over nine teraflops of double-precision performance per node, supporting larger workloads than ever before (up to 512GB).And there’s more.
The following are known issues with the CUDA 6.0 Release Candidate that will be resolved in the production release:‣ The minBlocksPerMultiprocessor parameter for the launch_bounds() qualifier only accepts values up to 16 when used in compiling for sm_50, eventhough values up to 32 are possible on that architecture.‣ There is a performance issue with the new SIMD video intrinsics __v*2() and __v*4() when used in compiling for the sm_50 architecture.‣ The sm_50 architecture supports 48 KB of shared memory per block; however, the check for this limit is not functioning properly in the compiler. This can allowprograms that use more than 48 KB of shared memory per block to compile successfully, although they will fail to run because the driver component does checkthe limit properly.‣ The MT19937 random number generator in the cuRAND library generates non-deterministic results for curandGenerateUniformDouble().‣ The NPP library function nppiAlphaComp_8u_AC4R() generates incorrect results when used with the NPPI_OP_ALPHA_ATOP_PREMUL option.‣ The NPP library functions FilterSobelHorizSecondBorder() and FilterSobelVertSecondBorder() may generate incorrect results.
