High-Performance and Scalable Designs of Programming Models for Exascale Systems

DK Panda from Ohio State University presented this talk at the Switzerland HPC Conference. “This talk will focus on challenges in designing runtime environments for Exascale systems with millions of processors and accelerators to support various programming models. We will focus on MPI, PGAS (OpenSHMEM, CAF, UPC and UPC++) and Hybrid MPI+PGAS programming models by taking into account support for multi-core, high-performance networks, accelerators (GPUs and Intel MIC) and energy-awareness. Features and sample performance numbers from the MVAPICH2 libraries will be presented.”

RCE Podcast Looks at EasyBuild Installation Framework

“EasyBuild, a software build and installation framework, can be used to automatically install software and generate environment modules. By using a hierarchical module naming scheme to offer environment modules to users in a more structured way, and providing Lmod, a modern tool for working with environment modules, we help typical users avoid common mistakes while giving power users the flexibility they demand. EasyBuild is developed by the High-Performance Computing team at Ghent University together with the members of the EasyBuild community, and is made available under the GNU General Public License (GPL) version 2.”

Video: Superscalar Programming Models – Making Applications Platform Agnostic

Dr. Rosa Badia from BSC/CNS presented this Invited Talk at SC15. “StarSs (Star superscalar) is a task-based family of programming models that is based on the idea of writing sequential code which is executed in parallel at run-time taking into account the data dependencies between tasks. The talk will describe the evolution of this programming model and the different challenges that have been addressed in order to consider different underlying platforms from heterogeneous platforms used in HPC to distributed environments, such as federated clouds and mobile systems.”

Slidecast: How to Make MPI Awesome – MPI Sessions

In this slidecast, Jeff Squyres from Cisco Systems presents: How to make MPI Awesome – MPI Sessions. As a proposal for future versions of the MPI Standard, MPI Sessions could become a powerful tool tool to improve system resiliency as we move towards exascale. “Now that we have brought these ideas to a larger audience, my hope is that we (the Forum) start refining these ideas to fit them into a future release of the MPI standard. Meaning: please don’t assume that exactly what is proposed in these slides are going to make it into the MPI standard.”

Paving the Way for Theta and Aurora

In this special guest feature, John Kirkley writes that Argonne is already building code for their future Theta and Aurora supercomputers based on Intel Knights Landing. “One of the ALCF’s primary tasks is to help prepare key applications for two advanced supercomputers. One is the 8.5-petaflops Theta system based on the upcoming Intel® Xeon Phi™ processor, code-named Knights Landing (KNL) and due for deployment this year. The other is a larger 180-petaflops Aurora supercomputer scheduled for 2018 using Intel Xeon Phi processors, code-named Knights Hill. A key goal is to solidify libraries and other essential elements, such as compilers and debuggers that support the systems’ current and future production applications.”

Best Practices – Dynamic Tuning for Energy Efficiency

“Today’s server systems provide many knobs which influence energy efficiency and performance. Some of these knobs control the behavior of the operating systems, whereas others control the behavior of the hardware itself. Choosing the optimal configuration of the knobs is critical for energy efficiency. In this talk recent research results will be presented, including examples of big data applications that consume less energy when dynamic tuning is employed.”

With GPUOpen, CGG Fuels Petroleum Exploration using AMD FirePro GPUs

Today AMD announced that CGG, a pioneering global geophysical services and equipment company, has deployed AMD FirePro S9150 server GPUs to accelerate its geoscience oil and gas research efforts, harnessing more than 1 PetaFLOPS of GPU processing power. Employing AMD’s HPC GPU Computing software tools available on, CGG rapidly converted its in-house Nvidia CUDA code to OpenCL for seismic data processing running on an AMD FirePro S9150 GPU production cluster, enabling fast, cost-effective GPU-powered research.

Code Modernization for Smarter Geophysics

Today Allinea announced plans to champion what it sees as a key survival message for the Energy industry when it exhibits at the Rice Oil and Gas HPC Conference in Houston next week. “We’ll be underlining to geophysicists at the conference the real commercial gains to be had from focusing on code performance,” said Robert Rick, Allinea’s VP of Sales, Americas. “HPC is helping the industry to operate more efficiently. The next step is for this market is to use code optimization to speed up the valuable seismic imaging and reservoir modeling processes, which are now essential to this industry.”

UCX: An Open Source Framework for HPC Network APIs and Beyond

“Unified Communication X (UCX) is a set of network APIs and their implementations for high performance computing. UCX comes from the combined efforts of national laboratories, industry, and academia to co-design and implement a high-performing and highly scalable communication APIs for next generation applications and systems. UCX solves the problem of moving data memory location “A” to memory location “B” considering across multiple type of memories (DRAM, accelerator memories, etc.) and multiple transports (e.g. InfiniBand, uGNI, Shared Memory, CUDA, etc. ), while minimizing latency, and maximizing bandwidth and message rate.”

Cyber Security: IDC Study Shows Wide Range of Corporate Preparedness

“The findings of a recent IDC study on the cybersecurity practices of U.S. businesses reveal a wide spectrum of attitudes and approaches to the growing challenge of keeping corporate data safe. While the minority of cybersecurity “best practitioners” set an admirable example, the study findings indicate that most U.S. companies today are underprepared to deal effectively with potential security breaches from outside or inside their firewalls.”
