You can generate a grayscale image from a color imageīy first calling nppiColorToGray() or nppiRGBToGray(). This function expects a single channel 8-bit grayscale input image. Demonstrates the recommended parameters to use with the nppiFilterCannyBorder_8u_C1R Canny Edge Detection image filter function. Added 7_CUDALibraries/cannyEdgeDetectorNPP.Demonstrates how any border version of an NPP filtering function can be used in the most common mode (with border controlĮnabled), can be used to duplicate the results of the equivalent non-border version of the NPP function, and can be used toĮnable and disable border control on various source image edges depending on what portion of the source image is being used Added 7_CUDALibraries/FilterBorderControlNPP.Updated 6_Advanced/shfl_scan to use newly added *_sync equivalent of the shfl intrinsics.Updated 0_Simple/simpleVoteIntrinsics to use newly added *_sync equivalent of the vote intrinsics _any, _all.The new Tensor Cores introduced in the Volta chip family. Demonstrates a GEMM computation using the Warp Matrix Multiply and Accumulate (WMMA) API introduced in CUDA 9, as well as Illustrates basic usage of Cooperative Groups within the thread block. Added 0_Simple/simpleCooperativeGroups.Added Cooperative Groups(CG) support to several samples notable ones to name are 6_Advanced/cdpQuadtree, 6_Advanced/cdpAdvancedQuicksort, 6_Advanced/threadFenceReduction, 3_Imaging/dxtc, 4_Finance/MonteCarloMultiGPU, 0_Simple/matrixMul_nvrtc.Demonstrates a conjugate gradient solver on GPU using Multi Block Cooperative Groups. Added 6_Advanced/conjugateGradientMultiBlockCG.Demonstrates single pass reduction using Multi Block Cooperative Groups. Added 6_Advanced/reductionMultiBlockCG.Demonstrates warp aggregated atomics using Cooperative Groups. Added 6_Advanced/warpAggregatedAtomicsCG.Demonstrates Spectral Clustering using NVGRAPH Library.
Opengl 4.3 collision with cubes windows#
Demonstrates binary_partition cooperative groups creation and usage in divergent path. Added warp aggregated atomic multi bucket increments kernel using labeled_partition cooperative groups in 6_Advanced/warpAggregatedAtomicsCG which can be used on compute capability 7.0 and above GPU architectures.Also makes use of asynchronousĬopy from global to shared memory using cuda pipeline which leads to further performance gain. Demonstrates tf32 (e8m10) GEMM computation using the WMMA API for tf32 employing the Tensor Cores. Demonstrates _nv_bfloat16 (e8m7) GEMM computation using the WMMA API for _nv_bfloat16 employing the Tensor Cores. Makes use of asynchronous copy from global to shared memory using cuda pipeline which leads to further performance gain.
Demonstrates double precision GEMM computation using the WMMA API for double precision employing the Tensor Cores. Demonstrates the stream attributes that affect L2 locality. Demonstrates asynchronous copy of data from global to shared memory using cuda pipeline. Added 0_Simple/globalToShmemAsyncCopy.
