In this video from the PASC16 conference, Andrew Lumsdaine from Indiana University presents: Context Matters: Distributed Graph Algorithms and Runtime Systems. “The increasing complexity of the software/hardware stack of modern supercomputers makes understanding the performance of the modern massive-scale codes difficult. Distributed graph algorithms (DGAs) are at the forefront of that complexity, pushing the envelope with their massive irregularity and data dependency. We analyze the existing body of research on DGAs to assess how technical contributions are linked to experimental performance results in the field. We distinguish algorithm-level contributions related to graph problems from “runtime-level” concerns related to communication, scheduling, and other low-level features necessary to make distributed algorithms work. We show that the runtime is an integral part of DGAs’ experimental results, but it is often ignored by the authors in favor of algorithm-level contributions.”
At ISC 2016 this week, SGI announced that Total’s SGI ICE X supercomputer, Pangea, was recognized as the industry’s top commercial supercomputer in the prestigious TOP500 list. “Our SGI ICE XA systems lead in delivering application performance in both homogeneous systems and hybrid systems with CPUs and accelerators,” said Gabriel Broner, vice president and general manager, high-performance computing at SGI. “Our production supercomputers continue to enable our customers to innovate and lead in their field, and occupy prominent positions in the prestigious TOP500 list.”
“Our latest product enhancements will solidify our customers’ investment in the next generation Intel Xeon Phi processor,” said Mark O’Connor, VP Product Management at Allinea. “Knights Landing’ has the potential to unleash new capabilities for HPC code users and our new release brings a powerful debugger, profiler and performance reports for tackling the essential preparatory work needed to optimize legacy code and realize the processor’s true potential for reducing software run times.”
Penguin Computing, a provider of high performance, enterprise data center and cloud solutions, announced its transition from pre-production deployments last year of systems based on the Intel Xeon Phi processor to full production for Penguin’s Tundra product family. “We received early access to the Intel Xeon Phi processor through Penguin Computing and its OCP-based Tundra Extreme Scale (ES) Series,” said James Laros, Principal Member of Technical Staff, Sandia National Laboratories. “We are seeing very promising results to date.”
“The June 2016 Irish Supercomputer List represents a seismic shake-up in the Irish HPC landscape. After a 2015 that saw only three new machines, the list has experienced a turnover of over 50% with three new Top500-class machines topping the list. High Performance Computing is alive and well in Ireland, with a combined national HPC output of over 1 Petaflop. On the global stage, Ireland is now at the envious position of being #2 in the world in terms of Top500 supercomputers per capita.”
With DDN’s high-performance GRIDScaler platform, Children’s Mercy can scale up or out to handle massive data ingest, processing, storage and collaboration. Not only does DDN deliver performance and scalability unmatched by traditional scale-out, enterprise NAS architectures, the GS7K meets the Center’s imposing requirements for a high-density, cost-effective solution.
“Tasks keep the CPUs busy. When a core is working, rather than waiting for work to be sent to it, the application progresses towards it conclusion. A caveat to all of this is to remember that tasking and threading models remain on the system it was created on. Tasks that use a shared memory space only work within the shared memory segment that the processing cores can get to. Shared memory on the CPU side of the system is separate from the shared memory on the coprocessor. The threads created will remain on the part of the system where it started.”
In this video from ISC 2016, Barry Davis from Intel describes the company’s brand new Intel Xeon Phi Processor and how it fits into the Intel Scalable System Framework. “Eliminate node bottlenecks, simplify your code modernization and build on a power-efficient architecture with the Intel Xeon Phi™ processor, a foundational element of Intel Scalable System Framework. The bootable host processor offers an integrated architecture for powerful, highly parallel performance that will pave your path to deeper insight, innovation and impact for today’s most-demanding High Performance Computing applications, including Machine Learning. Supported by a comprehensive technology roadmap and robust ecosystem, the Intel Xeon Phi processor is a future-ready solution that maximizes your return on investment by using open standards code that are flexible, portable and reusable.”
Today Northumbria University announced that its has become one of the first UK sites to deploy Intel Omni-Path Architecture (Intel OPA) for their centralized HPC infrastructure. Deployed by BIOS IT, this is the first stage of Northumbria University’s long term objective to provide its students, researchers and faculty members with a state of the art multipurpose heterogeneous computing facility.
The SGI Management Suite’s system health monitoring and management capability collects health status information on fundamental system’s functions such as memory, CPU and power. It identifies changes that require action, automatically alerts the system administrator, and provides proactive solutions to correct the problem.
