    from Multicore World Added 7 0 0

    The era of monolithic custom built supercomputers are drawing to a close giving rise to a new era of ubiquitous cloud based supercomputing. Although the transition to cloud based supercomputing may be inevitable the path is anything but clear as the benefits of abundant low-cost commoditized computing infrastructure also gives rise to a new set of big-data and HPC challenges. Alex St. John, an early pioneer in GPU based computing and streaming media technology will present how new software techniques may address power, bandwidth, software development and compute density challenges that can’t be addressed by new innovative hardware approaches alone. Although the hardware will certainly evolve, the tools, platforms and approaches to large scale software development will also have to be revolutionized to take advantage of the dramatic changes taking place in the world of HPC.

      I Multicore World, 27-28 March 2012, Wellington, New Zealand Abstract- We use applications. Computers are nothing more than appliances to support software we care about. Back when clock speeds increased between hardware generations, we could get away with a hardware obsession. Those days, however, are gone forever. With cores proliferating on a chip from one generation to the next, parallelism is the defining feature of our systems; and since automatic parallelism is unlikely to ever succeed, programmers are forced to write parallel software “by hand”. There is no simple solution to this software problem. We can’t sit around hoping for an elegant “silver bullet” that will make this problem go away. Instead, we have to take action and approach our software problems from many directions at once. We need to: embrace hardware/software co-design so people can actually use the hardware we build, create a low level, portable software foundation to protect expensive investments in parallel software, and recognize that over time, more and more programmers will be domain experts rather than trained computer scientists. In this talk, I will address these 3 issues in the context of my work on Intel’s 80 and 48 core research processors, industry standards such as OpenCL and OpenMP, and systematic development of software frameworks derived from design pattern languages (NB.- Apologies for the quality of the audio)

          I Multicore World - 27, 28 March 2012 - Wellington, New Zealand Paul Bone (University of Melbourne, Australia - NICTA)."Automatic Parallelisation" In this presentation we describe the components of a functioning automatic parallelisation system; giving a high-level description of each component and its interaction with the others. The presentation stresses the importance of profiling as profiling data is the basis of parallelisation decisions. This is true for both automatic or manual parallelisation. This work was published as: Paul Bone, Zoltan Somogyi and Peter Schachte: Estimating the overlap between dependent computations for automatic parallelization. Theory and Practice of Logic Programming, 27th Int'l. Conference on Logic Programming (ICLP'11) Special Issue, volume 11, issue 4-5. Lexington, Kentucky, July 2011. Finally, the presentation shows another profiler, ThreadScope, a visual profiler designed to profile the parallel execution of programs. Being visual it provides the programmer with a strong intuition of their program's behaviour. This profiler is extensible and can be modified to work on other systems, as we have already shown in: Paul Bone and Zoltan Somogyi: Profiling parallel Mercury programs with ThreadScope. 21st Workshop on Logic-based methods in Programming Environments. Lexington, Kentucky, July 2011. These papers may be downloaded from: http://www.mercury.csse.unimelb.edu.au/information/papers.html

            The Contribution of MultiCore to Server Architecture. - A two parts joint presentation from Martin McKendry (Open Parallel) and Stephan Friedl (Cisco). Over two days. I Multicore World - 27-28 March 2012, Wellington, New Zealand Part 1: How We Got to Here The current generation of multicore, multiprocessor servers provide remarkable compute densities. Blade or 2U servers packing 32 cores and half a terabyte of memory are readily available. As servers continue to increase core and memory densities, an emerging problem in the Data Center is keeping these platforms busy. This presentation will focus on the evolution of hardware architecture over the last 5 years, examining how networking, storage, and processor advances led to advances in virtualization and set the scene for big data. Stephan Friedl - Systems Architect. Cisco, United States BIO - I have been developing and designing for multiprocessor/multicore systems for nearly 20 years. I started thread-reentrant programming on DEC Alpha boxes while developing the global scheduling and distribution planner for British Oxygen Corporation (BOC gases). Through the years I have worked at large multinational technology corporations, small VC funded startups and done independent consulting. I currently work as a Systems Architect at Cisco Systems and help design dense Virtual Desktop architectures for deployment on Cisco's line of multi-core server blades. In my spare time I exhaust myself trying to keep up with my wife and three children. If I'm still able to think at the end of the day I continue to write code in a probably hopeless attempt to retain my developer cred. My family lives outside Boulder Colorado, and we are avid skiers in the winter and enjoy camping, astronomy and biking during the summers.

I Multicore World - 27-28 March 2012, Wellington, New Zealand Part 2: Implications for the Future The current generation of multicore, multiprocessor servers provide remarkable compute densities. The next generation will advance storage capacities through directly addressable large-scale storage. Initially, this will be accessible through legacy interfaces, but over time new application structures will evolve to exploit advanced architectures and multiple cores, both on the client and the server. This presentation will explore the limits of legacy interfaces and processing models and show where rapid advances in software architecture are likely to force new business models.

                from Multicore World Added 62 0 0

                I Multicore World, 27-28 March 2012, Wellington - New Zealand. Abstract - Multicore Computing, Green Computing and Cloud Computing can be productively interlinked. Increasing overall energy efficiency is both financially and environmentally responsible. Cloud Computing facilitates aggregation of servers and collection of workloads so as to maximise economies of scale in power, communications and cooling technology. Finally, Multicore CPUs provide better performance per Watt than increased frequencies on the less parallel architectures of previous processors, and have unique forms of processing consolidation to offer. Our research examines two key aspects of Cloud Computing workloads: (1) applying novel scheduling policies that may employ periods of higher power usage in order to produce lower overall energy consumption, and (2) taking advantage of the particular processing consolidation options that multicore CPUs can provide. Performing experiments on 16-core servers, we aim to rapidly and automatically classify processing workloads at run-time, so as to optimally balance overall energy consumption with process completion times. BIO - Dr. David Eyers. Lecturer. Otago University, Dunedin, New Zealand Before joining the University of Otago Computer Science Department, David worked as a senior research associate at the University of Cambridge, from where he was awarded his PhD. He has undergraduate degrees in Computer Engineering and Maths from UNSW in Sydney, Australia. David's research interests are in distributed systems, particularly regarding security enforcement and data dissemination mechanisms within wide-area applications. This has become particularly relevant within cloud computing: large-scale public services, such as electronic health record repositories, must manage sensitive data in a secure manner. David's desire to examine green computing, and to become more involved with distribution at the level of CPU cores, has been met by him joining the Otago Systems Research Group, and its existing research projects in those fields
