Although event tracing of parallel applications offers highly detailed performance information, tracing on current leading edge systems may lead to unacceptable perturbation of the...
Middleware for parallel and distributed systems is designed to virtualize computation and communication resources so that a more and consistent view of those resources is presente...
MPI provides a portable message passing interface for many parallel execution platforms but may lead to inefficiencies for some platforms and applications. In this article we sho...
IP forwarding is one of the main bottlenecks in Internet backbone routers, as it requires performing the longest-prefix match at 10Gbps speed or higher. IPv6 forwarding further ex...
