We systematically evaluate the performance of five implementations of a single, user-level communication interface. Each implementation makes different architectural assumptions ...
Power dissipation is a major concern not only for portable systems, but also for high-performance systems. In the past, energy consumption and processor heating was reduced mainly...
In benchmarking I/O systems, it is important to generate, accurately, the I/O access pattern that one is intending to generate. However, timing accuracy ( issuing I/Os at the desi...
