For many applications of scientific computing, reduction operations may cause a performance bottleneck. In this article, the performance of different coarse- and fine-grained methods for implementing the reduction is investigated. Fine-grained reductions using atomic operations or fine-grained explicit locks are compared to the coarse-grained reduction operations supplied by OpenMP and MPI.
