The <i>Gordon</i> data intensive supercomputer entered service in 2012 as an allocable computing system in the NSF Extreme Science and Engineering Discovery Environment (XSEDE) program. <i>Gordon</i> has several innovative features that make it ideal for data intensive computing including: 1,024, compute nodes based on Intel's Sandy Bridge (Xeon E5)(More)
We present results of large-scale three-dimensional simulations of supersonic Euler turbulence with the piece-wise parabolic method (PPM) and multiple grid resolutions up to 2048 3 points. Our numerical experiments describe non-magnetized driven turbulent flows with an isothermal equation of state and an rms Mach number of 6. We discuss numerical resolution(More)
The Internet offers tremendous potential for rapid development of mechanical products to meet global competition. In the past several years, a variety of geometric algorithms have been developed to evaluate computer-aided design (CAD) models with respect to manufacturing properties such as feedability, fixturability, assemblability, etc. Unfortunately ,(More)
The demand for virtualization within high-performance computing is rapidly growing as new communities, driven by both new application stacks and new computing modalities, continue to grow and expand. While virtualization has traditionally come with significant penalties in I/O performance that have precluded its use in mainstream large-scale computing(More)
We use large-scale three-dimensional simulations of supersonic Euler turbulence to get a better understanding of the physics of a highly compressible cascade. Our numerical experiments describe non-magnetized driven turbulent flows with an isothermal equation of state and an rms Mach number of 6. We find that the inertial range velocity scaling deviates(More)
The discovery of the Higgs boson by the Large Hadron Collider (LHC) has garnered international attention. In addition to this singular result, the LHC may also uncover other fundamental particles, including dark matter. Much of this research is being done on data from one of the LHC experiments, the Compact Muon Solenoid (CMS). The CMS experiment was able(More)
The increasing expansion of computations in non-traditional domain sciences has resulted in an increasing demand for research cyberinfrastructure that is suitable for small- and mid-scale job sizes. The computational aspects of these emerging communities are coming into focus and being addressed through the deployment of several new XSEDE resources that(More)
Simulations running on the top supercomputers are routinely producing multi-terabyte data sets. Enabling scientists, at their home institutions, to analyze, visualize and interact with these data sets as they are produced is imperative to the scientific discovery process. We report on interactive visualizations of large simulations performed on Kraken at(More)
Doppler vibrometers are used by many research groups to monitor the motion of the tympanic membrane (TM) and of middle ear ossicles for in vivo and in vitro studies. Power densities in these applications reach 80 W/cm(2). To determine the safe limit of exposure, a cw dye laser at a wavelength of 633 nm was used to investigate the threshold of thermal damage(More)
