Growing performance gap between processors and main memory has made it worthwhile to consider off-chip data accesses in multi-query processing [2], [1], [3]. Exploiting data-sharing opportunities among concurrent queries can be critical for effective utilization of the underlying shared memory hierarchy. Given a set of queries, there may be a common retrieval operation for several cases to the same...
Software architecture (SA) documentation provides a blueprint of a software-intensive system for the communication between stakeholders about the high-level design of the system. In open source software (OSS) development, a lack of SA documentation may hinder the use and further development of OSS, but how much "architecture" documentation is enough and appropriate is largely dependent on...
Internet flows characteristics are important reference for network behaviors research. However, there are few latest related studies and comparative analysis on different networks is especially rare. Based on traffic traces from CAIDA and CERNET, this paper presents a detailed and comprehensive comparison on Internet flows characteristics, including the fine-grained distributions of lifetime, size,...
This paper is concerned with the problem of nonfragile H∞ filtering for discrete-time nonlinear systems in Takagi-Sugeno's form. Additive interval uncertainty which reflects imprecision in filter implementation due to finite word length effects is considered. Based on vertex theory and probabilistic robust approach, deterministic and randomized filtering algorithms are proposed, respectively. Compared...
This paper presents and evaluates a cache hierarchy-aware code parallelization/mapping and scheduling strategy for multicore architectures. Our proposed parallelization/mapping strategy determines a loop iteration-to-core mapping by taking into account the data access pattern of an application and the on-chip cache hierarchy of a target architecture. The goal of this step is to maximize data locality...
