New Whitepaper: File I/O on Intel Xeon Phi (RAM disks, VirtIO, NFS, and Lustre)

colfax

“This paper provides information and benchmarks necessary to make the choice of the best file system for a given application from a number of the available options: RAM disks, virtualized local hard drives, and distributed storage shared with NFS or Lustre. We report benchmarks of I/O performance and parallel scalability on Intel Xeon Phi coprocessors, strengths and limitations of each option.”

Boosting Electric Car Batteries with Simulation

“Over the past two and half years, the team worked on a DOE-funded project, Computer-Aided Engineering for Electric Drive Vehicle Batteries (CAEBAT), to combine new and existing battery models into engineering simulation software to shorten design cycles and optimize batteries for increased performance, safety and lifespan. In order to achieve these goals the team has been modeling thermal management, electrochemistry, ion transport and fluid flow.”

Global HPC Market to Reach 38.1 Billion by 2018

“The continuous demands of competition help maintain strong markets for high performance computing systems, even amidst apparent paradoxes. Our surveys show that HPC users are bucking the trend of reducing spending on servers, and research indicates modest growth for HPC in all economic sectors (industrial, academic, and government) over the next four years.”

New Paper: Petascale Multiphase Flow Solutions on Titan Supercomputer

porous

“In this paper, we consider a coupled solution in which a multiphase flow simulator is coupled to an analysis approach used to extract the interfacial geometries as the flow evolves. This has been implemented using MPI to target heterogeneous nodes equipped with GPUs. The GPUs evolve the multiphase flow solution using the lattice Boltzmann method while the CPUs compute upscaled measures of the morphology and topology of the phase distributions and their rate of evolution. Our approach is demonstrated to scale to 4,096 GPUs and 65,536 CPU cores to achieve a maximum performance of 244,754 million-lattice-node updates per second (MLUPS) in double precision execution on Titan.”

“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.”
