Parallel computation patterns histogram
WebParallel patterns—parallel histogram computation An introduction to atomic operations and privatization Abstract. This chapter introduces the parallel histogram computation pattern and the concept of atomic operations. It shows that atomic operations to the same location are serialized and their throughput is determined by their latency.
