Data-intensive problems challenge conventional computing architectures with demanding CPU, memory, and I/O requirements. Experiments with three benchmarks suggest that emerging hardware technologies can significantly boost performance of a wide range of applications by increasing compute cycles and bandwidth and reducing latency.
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 describes our approach to adapting a text document similarity classifier based on the Term Frequency Inverse Document Frequency (TFIDF) metric to two massively 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)
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)
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)
Resource rich clusters are an emerging category of computational platform where cluster nodes have both CPUs as well as high-performance I/O cards. These clusters target specific applications such as digital libraries, web servers, and multimedia kiosks. The presence of communication endpoints at locations other than the host CPU requires a re-examination… (More)
The recent emergence of high-quality floating-point libraries for FPGAs has sparked a renewed interest in accelerating scientific applications through Reconfigurable Computing (RC) techniques. Unfortunately, the sheer size of these floating-point units makes it difficult to house a large number of units in a single FPGA. In order to support the adaptation… (More)
