SHOW PREVIEW: SC10


combines Cray’s new Gemini system interconnect with powerful AMD Opteron processors, and is designed to bring production petascale computing to a new and expanded base of HPC users. Fully upgradeable from the Cray XT5 and Cray XT6 systems, the Cray XE6 supercomputer delivers improved network performance and additional enhancements such as improved network resiliency, a scalable software environment and the ability to run a broad array of ISV applications with the latest version of the Cray Linux Environment.


The rack-mounted Cray CX1000 system is built on Intel Xeon processors and features three different configurations. The compute-based Cray CX1000-C utilises the dual-socket Intel Xeon Processor 5600 series for scale-out cluster computing; the Cray CX1000-G features Nvidia Tesla GPUs for accelerator-based HPC; and the Cray CX1000-S offers users symmetric multiprocessing (SMP) nodes for up to 128 cores of ‘big memory’ computing built on Intel’s QuickPath Interconnect technology. www.cray.com


CRC Press – Taylor & Francis publishes innovative textbooks and reference books on the latest research and developments in computational science and engineering. It will be featuring the


latest publications, including the newest titles in its Computational Science book series, edited by Horst Simon. Key titles on show include: High Performance Computing for Scientists and Engineers, by Gerhard Wellein and Georg Hager, Scientific Data Management, edited by Arie Shoshani and Doron Rotem, and Scientific Computing with Multicore and Accelerators, edited by Jakub Kurzak, David Bader, and Jack Dongarra. www.crcpress.com


EPCC has a strong presence at this year’s SC10. The booth will showcase the wide range of work that EPCC undertakes, including Grid accounting software, fusion simulations, exascale computing, industrial partnerships and much, much more.

The EPCC is also involved with a number of other booths, including those for the European project PRACE, and EUFORIA. Finally, it is also helping to provide tutorials on OpenMP and Co-array Fortran, and have a number of posters on a range of topics in the poster sessions. www.epcc.ed.ac.uk


The Ethernet Alliance booth at SC10 will feature a comprehensive multi-vendor, multi-technology display of Ethernet’s ability to support high-performance networking. This showcase will highlight how Ethernet delivers a high-performance enterprise data centre infrastructure while converging interprocessor communication, storage and server application communications over a unified network. Visitors at the Ethernet Alliance booth will be able to see equipment from multiple vendors supporting a comprehensive technology demonstration that will include 10GbE, 40GbE and 100GbE as well as converged traffic including Fibre Channel over Ethernet, (FCoE), 10GBaseT, iSCSI, iWARP and RoCE. The live demonstrations will showcase these various solutions as enabled through a unique interoperability setting. www.ethernetalliance.org


The European Middleware Initiative will be exhibiting at the show. The EMI project was created on 1 May 2010 out of the joint efforts of European distributed computing middleware providers, ARC, gLite, Unicore and dCache. The project’s goal is to support and evolve the European and international research infrastructures and allow an increasing number of scientists and researchers to access resources, data and applications across the world. EMI’s main goals are to improve the reliability, usability and stability of the middleware services, according to the requirements of users and infrastructure providers.


EMI plans to consolidate the existing middleware services, to make them simpler and easier to use, by adopting, improving and proposing working standards and by carefully


integrating proven and new technologies. More than one hundred software developers, testers, designers, team leaders, project managers from 26 institutes in 18 countries, in Europe and outside are now working together to implement this vision. www.eu-emi.eu


Extoll will be demonstrating its technology aimed at performance computing users whose applications are currently limited by latency, scalability or power. Extoll technology is a communication solution that enables ultra-low latencies and avoids costly and power-hungry external switches. Unlike currently used equipment, the product is an integral part of the HPC system that provides inherent support for multicore environments, virtually


unlimited scalability and a tight coupling between computational units. As part of Extoll, Velo minimises the communication overhead, which results in ultra-low latency communication. The switch-less design technology integrates all switching resources onto the add-in card; with this technology external switches and their associated disadvantages like costs, power and inflexibility can be completely avoided. www.extoll.de


The Fraunhofer Institute for Industrial Mathematics will be launching GPI, a new interface for application development for multicore architectures. GPI stands for Global Address Space Programming Interface. It implements the PGAS (programming model on the API level). The advantages of GPI include the global address space, which makes programming more productive, and its true asynchronous communication model. It also offers performance at wire speed, and excellent scalability on large multicore systems.


GPI directly extends the simple thread- based programming model from the node ➤
