Abstract. This article presents the C++ library vShark which reduces the intranode communication overhead of parallel programs on clusters of SMPs. The library is built on top of m...
Abstract. The ability to offload functionality to a programmable network interface is appealing, both for increasing message passing performance and for reducing the overhead on t...
The MPI standard provides tool builders with an efficient profiling interface, PMPI. Although many tools have successfully used this interface, it has three major drawbacks: a n...
Network performance measurement and prediction is very important to predict the running time of high performance computing applications. The LogP model family has been proven to b...
