We present a novel parallel auction algorithm implementation for solving the linear sum assignment problem. It is implemented using the message passing interface (MPI) on a computer cluster. Our approach enables dynamic computational load balancing over all processors throughout all steps of the algorithm's execution. We show that the performance of our approach is superior to existing approaches...
Malicious botnets have been around for years. Although the information security community has developed many countermeasures for combating botnets, the recent trend of smaller botnets and the rise of super-botnets (i.e., networks of independent botnets) that are more sophisticated and highly resistant to the current countermeasures pose a serious threat to the entire industry. We have conducted a...
For large scale, high performance Video Surveillance Systems, performance and the Security Management Process are intertwined. Confidentiality and Privacy are increasingly crucial factors determining the acceptance of the system. The current solution is based on a distributed architecture, utilizing high performance and real time characteristics of the base system. It presents an evaluation of existing...
This paper presents a dynamic self-organizing design for a server cluster that supports multiple services with different priorities. Our system dynamically allocates jobs to servers in a server cluster, while maintaining certain QoS objectives for each service. A "Local leader" is dynamically set up for each service, and it controls the membership of its service, and thus the cluster size...
