Why We Need Chapel for Large-scale Parallel Computing

“I believe programmers have never had a decent programming language for large-scale parallel computing. By “decent,” I mean one that contains sufficient concepts for expressing the parallelism and locality control required to leverage supercomputers, while also being as general, effective, and feature-rich as languages like Fortran, C, C++, or Java. Ideally, such a language would strive to be more than simply “decent” and feel as attractive and productive to programmers as Python or MATLAB are.”

Video: PRACE Award Winners – Sustained Petascale Seismic Simulations

In this video from ISC’14, Alex Heinecke from Intel and Sebastian Rettenberger from the Technical University of Munich describe their award-winning paper on volcano simulation. “Seismic simulations in realistic 3D Earth models require peta- or even exascale compute power to capture small-scale features of high relevance for scientific and industrial applications. In this paper, we present optimizations of SeisSol — a seismic wave propagation solver based on the Arbitrary high-order accurate DERivative (ADER) Discontinuous Galerkin method on fully adaptive, unstructured tetrahedral meshes — to run simulations under production conditions at petascale performance.”

Remote Viz in the Cloud: NICE DCV Test Drive now available on AWS

The NICE Software group has announced the availability of a new AWS Test Drive for NICE Desktop Cloud Visualization (DCV).

Video: Transtec Remote Visualization

“Instead of mass workstation upgrades, Remote Visualization allows incremental provisioning, on-demand allocation, better management and efficient distribution of interactive sessions and licenses. Racked workstations or blades typically have lower maintenance, cooling, replacement costs, and they can extend workstation (or laptop) life as “thin clients”.

International Supercomputing Conference Changes Name to ISC High Performance for 2015

The ISC’15 event will be renamed ISC High Performance and will take place July 12 – 16, 2015 in Frankfurt, Germany.

Software Defined Storage for Dummies

If you work with big data in the cloud or deal with structured and unstructured data for analytics, you need software defined storage. Software defined storage uses standard compute, network, and storage hardware; the storage functions are all done in software.

RSC Announces Record Compute Density with Xeon Phi at ISC’14

Russian supercomputing vendor RSC Group announced world record compute and power density with their RSC PetaStream and RSC Tornado based clusters.

Video: Applications Performance Optimizations – Best Practices

“To achieve good scalability performance on the HPC scientific applications typically involves good understanding of the workload through performing profile analysis, and comparing behaviors of using different hardware which pinpoint bottlenecks in different areas of the HPC cluster. In this session, a selection of HPC applications will be shown to demonstrate various methods of profiling and analysis to determine the bottleneck, and the effectiveness of the tuning to improve on the application performance.”
