Comparison of Efficient parallel Index Algorithms used for RDF data store using Graphical processing unit with CUDA

The exponential growth of semantic web and the resultant generation of large-scale RDF (Resource Description Framework) triples pose new challenges in the domain of RDF-storage and retrieval.Graphical processing units (GPUs) are being actively probed in the area of Big Data study, machine learning, and augmented certainty ever since ,such applications are categorized by massive data spanned and produced over distributed network. GPUs be responsible for a parallel programming agenda using CUDA (Compute Unified Device Architecture) that can be developed to proficiently collected and make inferences on these massive data-sets.

Abstract

During the past years a vast number of online file storage services have been introduced .while several of these services provide basic functionality such as an uploading and retrieving files by a specific user, more advanced services offer features such as shared folders, real-time collaboration ,minimization of data transfers or unlimited storage space. Within this report I am giving an overview of existing file storage solutions, and also try to analyze the Drop-box client software as well as its transmission protocols, show the weaknesses and possible attack vectors. And conclude by discussing the security improvements.

Key words: cloud computing, drop-box, attacks
