Parallel computation patterns histogram

WebMay 14, 2012 · Let the histogram be stored in an integer array local_histogram of 256 elements (I assume the images are grayscale). At the last step a global reduction with summation is performed with MPI_Reduce (): MPI_Reduce (local_histogram, histogram, 256, MPI_INT, MPI_SUM, 0, MPI_COMM_WORLD);
