OpenCL for Performance

OpenCL

“OpenCL is a fairly new programming model that is designed to help programmers get the most out of a variety of processing elements in heterogeneous environments. Many benchmarks that are available have demonstrated that excellent performance can be obtained over a wide variety of devices. Rather than lock an application into one specific accelerator, by using OpenCL, applications can be run over on a number of different architectures with each showing excellent speedups over a native (host cpu) implementation.”

KAUST is the Latest Intel Parallel Computing Center

article-logo-KAUST

KAUST in Saudi Arabia has been named as the latest Intel Parallel Computing Center. “The new PCC aims to provide scalable software kernels common to scientific simulation codes that will adapt well to future architectures, including a scheduled upgrade of KAUST’s globally Top10 Intel-based Cray XC40 system. In the spirit of co-design, Intel PCC at KAUST will also provide feedback that could influence architectural design trade-offs.”

Video: First Look at Intel Optane Non-volatile Memory

optane

“At IDF, Intel introduced Intel Optane technology, which is based on the revolutionary 3D XPoint non-volatile memory media and combined with the company’s advanced system memory controller, interface hardware and software IP, to unleash vast performance potential in a range of forthcoming products. Intel Optane technology will first come to market in a new line of high-endurance, high-performance Intel SSDs beginning in 2016. The new class of memory technology will also power a new line of Intel DIMMs designed for Intel’s next-generation data center platforms.”

Video: Panel Discussion on Supercomputing for Aerospace

Panelists (left to right): Jeff Dawson, Bill Gropp, Mark Seager

In this video from the AIAA Aviation Conference 2015, panelists discuss Supercomputing: Roadmap and its Future Role in Aerospace Engineering. “Supercomputing has made significant contributions in aerospace engineering in recent decades, including advances in computational fluid dynamics that has fundamentally altered the way aircraft are designed. And the relentless growth in high-performance computing power holds promise of huge leaps in engine performance and other aerospace technology.”

HPC People on the Move – August Edition

“The complexity and scale of weather and climate simulation have led weather centers and research groups to turn to their own community, either through direct collaboration or open source software initiatives, to increase performance and usability of these hugely complex models.”

PSC Retires Blacklight Supercomputer to Make Way for Bridges

The big memory “Blacklight” system at the Pittsburgh Supercomputer Center will be retired on Aug 15 to make way for the new “Bridges” supercomputer. “Built by HP, Bridges will feature multiple nodes with as much as 12 terabytes each of shared memory, equivalent to unifying the RAM in 1,536 high-end notebook computers. This will enable it to handle the largest memory-intensive problems in important research areas such as genome sequence assembly, machine learning and cybersecurity.”

Tianhe-1A Supercomputer Shuts Down After Catastrophic Blast in China

Photo taken on Aug. 13, 2015 shows broken glass and damaged windows at the National Supercomputer Center in Tianjin after a huge warehouse explosion.

A warehouse explosion in the city of Tianjin has killed 17 people, resulting in a shutdown of the nearby Tianhe-1A supercomputer. Not to be confused with the Tianhe-2 system (currently ranked at #1), the 2.57 Petaflop Tianhe-1A system is currently #24 on the June 2015 TOP500 list.

Colfax to Offer Free Online Training for Intel Code Modernization

how

Today Colfax International announced free online workshops on parallel programming and optimization for Intel architecture, including Intel Xeon processors and Intel Xeon Phi coprocessors. “The Hands-on Workshop (HOW) series will introduce best practices to researchers and developers to efficiently extract maximum performance out of modern parallel processors, achieving shorter time to solution, higher research productivity, and future-proof design.”

Ray Tracing with Embree Kernels using Intel Xeon Phi

Embree

The Embree kernel approach, using the Intel Xeon Phi coprocessor is applicable to many situations. The implementation can be tuned to the hardware available, using different vector widths and workloads per ray. With a flexible toolkit for rendering, applications can take advantage of the latest hardware acceleration to achieve maximum performance.
