A new paper on porting hydrodynamics code to hybrid supercomputers is available from Jack Dongarra and company at the University of Tennessee.
Colfax Research has published a new white paper entitled “Cluster-Level Tuning of a Shallow Water Equation Solver on the Intel MIC Architecture.” Written by Andrey Vladimirov, the paper demonstrates the optimization of the execution environment of a hybrid OpenMP+MPI computational fluid dynamics code (shallow water equation solver) on a cluster enabled with Intel Xeon Phi coprocessors.
“Our annual ‘Budget Map’ report series looks at the relative spending between all of the products, components, and services that make up the HPC market. With six years of end user data, we get a strong grip on where the money is flowing, whether it’s on big items like clusters and storage, or on topical things like power consumption, programming, or compute cycles in public cloud. We also get a sense of future budget outlook and how the market is likely to evolve.”
“The OpenSFS Benchmarking Working Group (BWG) was created with the intent of defining an I/O benchmark suite to satisfy the requirements of the scalable parallel file system users and facilities. The first step toward this end was identified as characterization of I/O workloads, from small- to very large-scale parallel file systems, deployed at various high-performance and parallel computing (HPC) facilities and institutions. The characterization will then drive the design of the I/O benchmarks that emulate these workloads.”
GPU Boost is a relatively simple way to increase performance by up to 17.5%.
This report, part of our Site Census research, provides an examination of the storage characteristics and capacities found in a sample of HPC user sites.
