Performance Evaluation of a Two-Dimensional Flood Model on Heterogeneous High-Performance Computing Architectures

Conference Sharif, Md Bulbul ; Ghafoor, Sheikh ; Hines, Thomas M. ; ...

This paper describes the implementation of a two-dimensional hydrodynamic flood model with two different numerical schemes on heterogeneous high-performance computing architectures. Both schemes were able to solve the nonlinear hyperbolic shallow water equations using an explicit upwind first-order approach on finite differences and finite volumes, respectively, and were conducted using MPI and CUDA. Four different test cases were simulated on the Summit supercomputer at Oak Ridge National Laboratory. Both numerical schemes scaled up to 128 nodes (768 GPUs) with a maximum 98.2x speedup of over 1 GPU. The lowest run time for the 10 day Hurricane Harvey event simulation atmore »« less

Towards New Metrics for High-Performance Computing Resilience

Conference Hukerikar, Saurabh ; Ashraf, Rizwan A ; Engelmann, Christian

Ensuring the reliability of applications is becoming an increasingly important challenge as high-performance computing (HPC) systems experience an ever-growing number of faults, errors and failures. While the HPC community has made substantial progress in developing various resilience solutions, it continues to rely on platform-based metrics to quantify application resiliency improvements. The resilience of an HPC application is concerned with the reliability of the application outcome as well as the fault handling efficiency. To understand the scope of impact, effective coverage and performance efficiency of existing and emerging resilience solutions, there is a need for new metrics. In this paper, wemore »« less
Re-Form: FPGA-Powered True Codesign Flow for High-Performance Computing In The Post-Moore Era

Conference Cappello, Franck ; Yoshii, Kazutomo ; Finkel, Hal ; ...

Multicore scaling will end soon because of practical power limits. Dark silicon is becoming a major issue even more than the end of Moore’s law. In the post-Moore era, the energy efficiency of computing will be a major concern. FPGAs could be a key to maximizing the energy efficiency. In this paper we address severe challenges in the adoption of FPGA in HPC and describe “Re-form,” an FPGA-powered codesign flow.

Hydraulic piston coring--A new era in ocean research

Conference Storms, M A ; Cameron, D H ; Nugent, W - Offshore Technol. Conf.; (United States)

In December of 1978, the Deep Sea Drilling Project, International Phase of Ocean Drilling, deployed the first hydraulically actuated piston corer. This coring system utilized a hydraulic piston principle. Fluid was pumped through the drill pipe, activating a piston driven core barrel which was ejected into the sediment at the rate of approximately 20 feet per second. This extremely high penetration rate effectively decoupled the core barrel from the heave induced vertical motion of the drill string. On completion of each coring operation, the core barrel assembly was retrieved by wireline. The core bit was then ''washed'' down to themore »« less
