Secure Computation with Differentially Private Access Patterns

WebJul 20, 2012 · Histogram generation is an inherently sequential operation where every pixel votes in a reduced set of bins. This makes finding efficient parallel implementations very desirable but challenging, because on graphics processing units thousands of threads may be atomically updating a short number of histogram bins. WebA Basic Histogram Kernel (cont.) – The kernel receives a pointer to the input buffer of byte values – Each thread process the input in a strided pattern __global__ void histo_kernel(unsigned char *buffer, long size, unsigned int *histo) {int i = threadIdx.x + blockIdx.x * blockDim.x; // stride is total number of threads lockwood drive charleston https://perituscoffee.com
