The XRootD system is used to transfer, store, and cache large datasets from high-energy physics (HEP). In this study we focus on its capability as distributed on-demand storage cache. Through exploring a large set of daily log files between 2020 and ...

All-pairs compute problems apply a user-defined function to each combination of two items of a given data set. Although these problems present an abundance of parallelism, data reuse must be exploited to achieve good performance. Several researchers ...

We observe three problems in existing storage and caching systems for deep-learning training (DLT) tasks: (1) accessing a dataset containing a large number of small files takes a long time, (2) global in-memory caching systems are vulnerable to node ...

Stream processing system (SPS) faces the problem of node failure when running over a long period of time. In addition, "exactly once" precise semantic guarantee is more and more important for SPS in some scenarios. In general, the approaches to achieve ...

When hardware cache coherence scales to many cores on chip, over saturated traffic of the shared memory system may offset the benefit from massive hardware concurrency. In this article, we investigate the cost of a write-update protocol in terms of on-...

This paper presents the design and implementation of a storage system for high performance systems based on a multiple level I/O caching architecture. The solution relies on Memcached as a parallel storage system, preserving its powerful capacities such ...

Managing a large scale RDF is a challenging problem in Semantic Web research domain since achieving efficiency and scalability is hard with keeping its intelligent level. Various approaches including indexing and keyword querying have been applied to ...

A data center network solution was designed to improve the network performance in processing the search traffic. The design is based on the analysis of the switching network search traffic model. According to the search traffic features, two technology ...

Nodes in Mobile Ad-Hoc Networks (MANETs) acquire data from servers through access points. In order to minimize this interaction, data caching at mobile nodes is employed. This work builds on a recently introduced cooperative caching scheme that uses the ...

This paper introduces a cooperation-based database caching system for Mobile Ad Hoc Networks (MANETs). The heart of the system is the nodes that cache submitted queries. The queries are used as indices to data cached in nodes that previously requested ...

We present cache-efficient chip multiprocessor (CMP) algorithms with good speed-up for some widely used dynamic programming algorithms. We consider three types of caching systems for CMPs: D-CMP with a private cache for each core, S-CMP with a single ...

This article focuses on data exchange in a distributed industrial application. It presents data distribution mechanism that imitates distributed shared memory by caching heavily used objects in memory. When configured and used properly such system is ...

Clustering is a common technique to overcome the wire delay problem incurred by the evolution of technology. Fully distributed architectures, where the register file, the functional units and the data cache are partitioned, are particularly effective to ...

To meet the diverse quality-of-service (QoS) requirements of emerging multimedia applications, communication networks should provide end-to-end QoS guarantees. QoS routing is the first step towards this goal. The route computing overhead caused by on-...

Clustered microarchitectures are becoming a common organization due to their potential to reduce the penalties caused by wire delays and power consumption. Fully-distributed architectures are particularly effective to deal with these constraints, and ...
