- Maximizing Data Locality in Distributed Systems
- The effectiveness of a distributed system hinges on the manner in which tasks and data are assigned to the underlying system resources. Moreover, nowadays large-scale distributed systems must accommodate heterogeneity in both the offered load and in the makeup of the available storage and compute capacity. The ideal resource assignment...

- Improving the Performance of Passive Network Monitoring Applications Using Locality Buffering
- This paper presents a novel approach for improving the performance of a large class of CPU and memory intensive passive network monitoring applications, such as intrusion detection systems, traffic characterization applications, and NetFlow export probes. The approach, called locality buffering, reorders the captured packets by clustering packets with the same...

- Parallel Processing Using Data Localization for MPEG2 Encoding on OSCAR Chip Multiprocessor
- Need for efficient processing of multimedia applications on PCs, mobile phones, games and so on have been increasing. Especially, low cost, low power consumption and high performance processors for multi-media applications have been expected. To satisfy the demands, chip multiprocessor architectures which allow giving scalability using multigrain parallelism are attracting...

- Sub-query gives no data and this results in an error
- I have various sub-queries which are used in a query which summarises related information. One of the sub-queries is designed to find out how many referrals were received in a particular month in a particular locality. There are 9 different localities. The user enters the parameters: [locality],...

- Locality-Aware and Churn-Resilient Load Balancing Algorithms in Structured Peer-to-Peer Networks
- Structured peer-to-peer overlay networks like Distributed Hash Tables DHTs map data items to the network based on a consistent hashing function. Such mapping for data distribution has an inherent load balance problem. Data redistribution algorithms based on randomized matching of heavily loaded nodes with light ones can deal with the...

- Optimization of Frequent Itemset Mining on Multiple-Core Processor
- Multi-core processors are proliferated across different domains in recent years. This paper studies the performance of frequent pattern mining on a modern multi-core machine. A detailed study shows that, even with the best implementation, current FP-tree based algorithms still under-utilize a multi-core system due to poor data locality and insufficient...

- Accelerating Security Applications With Intel Multi-Core Processors
- The transition to multi-core processors offers flexibility for development and optimization of higher performance applications. Multi-core architectures can significantly improve program flow so that cache memory associated with each execution core is used more effectively. With multiple caches, optimizing data locality is possible, driving higher cache-hit rates and improved overall...

- Load Balancing and Data Locality in Adaptive Hierarchical N-Body Methods: Barnes-Hut, Fast Multipole, and Radiosity
- Hierarchical N-body methods, which are based on a fundamental insight into the nature of many physical processes, are increasingly being used to solve large-scale problems in a variety of scientific/engineering domains. Applications that use these methods are challenging to parallelize effectively, however, owing to their nonuniform, dynamically changing characteristics and...

- A Super Scalar Sort Algorithm for RISC Processors
- The compare and branch sequences required in a traditional sort algorithm can not efficiently exploit multiple execution units present in currently available high performance RISC processors. This is because of the long latency of the compare instructions and the sequential algorithm used in sorting. With the increased level of integration...

- Wired Geometric Routing
- Routing substrates for overlay networks are an important building block for large distributed applications. Many existing substrates are based on a random identifier space and therefore do not respect node locality when routing data. This can lead to lower performance for locality-sensitive applications, such as web caching, distributed gaming, and...

- Directed Graph Embedding
- This paper proposes the Directed Graph Embedding DGE method that embeds vertices on a directed graph into a vector space by considering the link structure of graphs. The basic idea is to preserve the locality property of vertices on a directed graph in the embedded space. This paper uses the...

- Use Active Directory Application Mode to integrate apps and OS
- Directory-enabled software, such as Microsoft's Active Directory, has become a prominent part of many operating systems and applications. What has been lacking, however, is cross-directory integration to meet the diverse needs of authentication, Public Key Infrastructure PKI, single sign-on, and other features. Companies and developers have therefore had to rely...

- You've probably heard that location is the only thing that matters in real estate. Perhaps that idea should be extended to the location of availability service providers as well. Given the recent power outages experienced by much of the Northeast in August, having your offsite availability service provider only a...
