ON/OFF aggregation model is one of the efficient and accurate models for self-similar network traffic generation. In this paper we propose and compare three algorithms of implementing ON/OFF aggregation model, based on Cavium OCTEON CN3860 network processor, aimed to achieve high-bandwidth and real-time network traffic generation. The model is implemented in a multi-thread approach, in a token-bucket...
In high energy physics experiment the trigger system is crucial to reduce the quantity of data recorded on tape and the acquisition bandwidth requirements. This is particularly true in rare decays experiments. The NA62 experiment aims at measuring the branching ratio of K+ ?? ??+ ??????, predicted in the standard model (SM) at level of ~10-10. In this paper we describe the idea to use the commercial...
In earlier work, we showed that the one-sided communication model found in PGAS languages (such as UPC) offers significant advantages in communication efficiency by decoupling data transfer from processor synchronization. We explore the use of the PGAS model on IBM BlueGene/P, an architecture that combines low-power, quad-core processors with extreme scalability. We demonstrate that the PGAS model,...
