Network intrusion detection systems (NIDS) are critical network security tools that help protect computer installations from malicious users. Traditional software-based NIDS architectures are becoming strained as network data rates increase and attacks intensify in volume and complexity. In recent years, researchers have proposed using FPGAs to perform the(More)
In many scientific applications it is important to obtain precise data measurements over time for a large geographic region of interest. While these measurements can sometimes be performed at a distance using remote sensing techniques, it is often necessary to capture data using in-situ sensing where sensors are placed directly in the region of interest.(More)
Reconfigurable computing leveraging field programmable gate arrays (FPGAs) is one of many accelerator technologies that are being investigated for application to high performance computing (HPC). Like most accelerators, FPGAs are very efficient at both dense matrix multiplication and FFT computations, but two important aspects of how to deliver that(More)
This paper explores the view that the SAN network infrastructure can be an active computational entity capable of supporting certain classes of data intensive computations effectively during communication. The performance is achieved via the use of Field Programmable Gate Arrays (FPGAs) in the network interfaces (NIs). This paper describes the programming(More)
This paper describes our approach to adapting a text document similarity classifier based on the Term Frequency Inverse Document Frequency (TFIDF) metric to twomassively multi-core hardware platforms. The TFIDF classifier is used to detect web attacks in HTTP data. In our parallel hardware approaches, we design streaming, real time classifiers by(More)
