PSDG is a parallel synthetic data generator designed to generate "industrial sized" data sets quickly using cluster computing. PSDG depends on SDDL, a synthetic data description language that provides flexibility in the types of data we can generate.
Radio frequency identification is a wireless identification technology that relies on cheap tags that can be attached to objects and that nearby readers can track. The computer science and computer engineering department at the University of Arkansas started a project aimed at developing open-source RF middleware to address this latter problem. In this… (More)
Data provenance (information about the origin of data items and the transformations that they have gone through) can be a useful security tool, particularly for forensic investigation. Provenance information can also be used to enforce information assurance concepts like integrity and authenticity. The current techniques for finding data source and lineage… (More)
We present detailed experimental work involving a commercially available large scale shared memory MIMD paraliel computer having a software controlled cache coherence mechanism. The implementation of a scalable MIMD computer with hardware-controlled coherent shared hierarchical memory is indeed a formidable task and has yet to be effectively implemented. We… (More)
R adio frequency identification (RFID; http:// en.wikipedia.org/wiki/RFID) is an automatic identification technology that relies on cheap tags (transponders) that can be attached to objects (such as pallets, containers, ID badges, assets, vehicles , and pets) and that nearby readers can track. Although it isn't new, RFID technology has dramatically improved… (More)
We present a strudy that accentuates the performance and scalability aspects of directory-based cache coherence in multiprocessor systems.
