Exascale Computing—a fact or a fiction?

Abstract: Compute performance increased by orders of magnitude in the last few decades, made possible by continued technology scaling, increasing frequency, providing integration capacity to realize novel architectures, and reducing energy to keep power dissipation within limit. The technology treadmill will continue, and one would expect to reach Exascale level performance this decade; however, it's the same Physics that helped you in the past will now pose some barriers-Business as usual will not be an option. The energy and power will pose as a major challenge-an Exascale machine would consume in excess of a Giga-watt! Memory & communication bandwidth with conventional technology would be prohibitive. Orders of magnitude increased parallelism, let alone explosion of parallelism created by energy saving techniques, would increase unreliability. And programming system will be posed with even severe challenge of harnessing the performance with concurrency. This talk will discuss potential solutions in all disciplines, such as circuit design, test, architecture, system design, programming system, and resiliency to pave the road towards Exascale performance.

Big Data in 10 Years

Panel Discussion Abstract: There is a lot of excitement about “Big Data” which is at the intersection of the ongoing explosion in data (volumes, variety, and velocity at which it arrives and must be acted upon), the dramatic increase in cost-effective memory capacities, and the maturation of scale-out processing technologies. Huge investments are being made, and there are great expectations for the gains to be had and the range of applications that will be transformed by new data-driven approaches. What does the future hold? Will the changes indeed be transformative, and if so, what will some of the main changes be? What domains are likely to benefit the most? Or is this just a case of unrealistic expectations waiting to be debunked by reality? We will ask panelists drawn from diverse backgrounds to offer their opinions and, hopefully, to get into violent arguments!

HPC Cloud Bad; HPC in the Cloud Good

Abstract: For most of the past two decades -- since the rise of clustering in the mid-1990s -- the HPC community has created its own IT components for deploying, managing, monitoring, and using horizontally-scaled resources to run its technical workloads. Historically, these tools have differed significantly from those used in commercial data centers, primarily because enterprise workloads and scaling requirements were different than those seen in HPC. But big changes are afoot in the commercial data center -- changes that are being driven by several factors, including multicore, the rise of cloud computing, and the emergence of new and important workloads in the enterprise. Because of these and other trends, we are entering a new period of IT convergence in which the enterprise and HPC will share an increasing number of concerns and pain points. How this convergence unfolds and how actively the HPC community participates in this convergence will have far-reaching consequences for the future health of both enterprise computing and HPC.
