چکیده
High-performance data centers have been aggressively moving toward parallel technologies like clustered computing and multi-core processors. While this increased use of parallelism overcomes the vast majority of computational bottlenecks, it shifts the performance bottlenecks to the storage I/O system. To ensure that compute clusters deliver the maximum performance, storage systems must be optimized for parallelism. Legacy Network Attached Storage (NAS) architectures based on NFS v4.0 and earlier have serious performance bottlenecks and management challenges when implemented in conjunction with large scale, high performance compute clusters. pNFS takes a different approach by allowing compute clients to read and write directly to the storage, eliminating filer head bottlenecks and allowing single file system capacity and performance to scale linearly.

Design and Implementation of the Mobile Grid Resource Management System
We present a design of a Mobile Grid Resource Management System aimed at integrating mobile resources to an existing Grid infrastructure, while creating a platform for interoperability with telecommunications providers. In order to reduce the load on an existing infrastructure, we separate responsibilities and run additional features on mobile resources. Finally we present the Ikaros-EG impleme...

متن کاملA Greek Morphological Lexicon and Its Exploitation by Natural Language Processing Applications
This paper presents a large-scale Greek morphological lexicon, developed at the Software & Knowledge Engineering Laboratory (SKEL) of NCSR “Demokritos”. The paper describes the lexicon architecture and the procedure to develop and update it. The morphological lexicon was used to develop a lemmatiser and a morphological analyser that were exploited in various natural language processing applicat...
