Scientists across a wide range of domains increasingly rely on computer simulation for their investigations. Such simulations often spend a majority of their run-times solving large systems of linear equations that require vast amounts of computational power and memory. It is hence critical to design solvers in a highly efficient and scalable manner. Hypre is a high performance, scalable software...
The upcoming MPI-3.0 standard is expected to include non-blocking collective operations. Non-blocking collectives offer a new MPI interface, using which an application can decouple the initiation and completion of collective operations. However, to be effective, the MPI library should provide a high performance and scalable implementation. One of the major challenges in designing an effective non-blocking...
