Saving energy usually leads to performance degradation. We explore the limits of tag reduction on a multi-core processor with guaranteed performance effect. In our previous work, tag reduction is applied to multi-core processors and shows significant energy savings, meanwhile it causes performance overhead. In this paper, we have found out that when tag reduction is used on multi-core processors,...
Evaluating the performance of high-speed networks is a critical task due to the lack of reliable tools to generate traffic workloads at high rates. The current open-source software tools are not suitable to deal with high-speed networks as they present poor performance in terms of generated frames per second and scarce timing/rate accuracy in traffic generation. These issues are due to the intrinsic...
The current software tools for traffic generation suffer from poor performance in terms of frames per second and timing/rate accuracy, because of the intrinsic limitations of the PC architecture. This paper proposes a different approach, based on a cooperative PC/NP architecture: an advanced software tool runs on a host PC and instructs the processing engines of an Intel IXP2400 network processor,...
