Several high-performance computers now use field-programmable gate arrays as reconfigurable coprocessors. The authors describe the two major contemporary HPRC architectures and explore the pros and cons of each using representative applications from remote sensing, molecular dynamics, bioinformatics, and cryptanalysis.
Large-scale GPU clusters are gaining popularity in the scientific computing community. However, their deployment and production use are associated with a number of new challenges. In this paper, we present our efforts to address some of the challenges with building and running GPU clusters in HPC environments. We touch upon such issues as balanced cluster(More)
Electromagnetic position tracking devices are an integral part of many modern virtual reality systems. However, they have an inherent accuracy problem due to the dependence on the local electromagnetic field that can be easily distorted by a presence of magnetically active elements near the tracker’s transmitter or receiver. Several analytical techniques(More)
This case study presents the results of porting a production scientific code, called NAMD, to the SRC-6 high-performance reconfigurable computing platform based on field programmable gate array (FPGA) technology. NAMD is a molecular dynamics code designed to run on large supercomputing systems and used extensively by the computational biophysics community.(More)
In this paper, a systematic review of various contour functions and methods of their analysis, as applied in the field of shape description and characterization, is presented. Contour functions are derived from planar object outlines and are used as an intermediate representation from which various shape properties can be obtained. All the functions are(More)
We present an inexpensive hardware system for monitoring power usage of individual CPU hosts and externally attached GPUs in HPC clusters and the software stack for integrating the power usage data streamed in real-time by the power monitoring hardware with the cluster management software tools. We introduce a measure for quantifying the overall improvement(More)
HPC system architectures are shifting from the traditional clusters of homogeneous nodes to clusters of heterogeneous nodes and accelerators. The future of high-performance computing (HPC) from the technologies developed today to showcase the leadership-class compute systems, the supercomputers. These machines are usually designed to achieve the highest(More)
We present results of porting an important kernel of a production molecular dynamics simulation program, NAMD, to the Cell/B.E. processor. The non-bonded force-field kernel, as implemented in the NAMD SPEC 2006 CPU benchmark, has been implemented. Both single-precision and double-precision floating-point kernel variations are considered, and performance(More)
