Reminder: Presentation proposals DUE APRIL 15, 2012 Extreme Scaling Workshop from Blue Waters and XSEDE July 15-16, 2012 • Chicago, Illinois The April 15 deadline is approaching for presentation proposals for the Extreme Scaling Workshop, sponsored by the National Center for Supercomputing Applications' Blue Waters and eXtreme Science and Engineering Discovery Environment (XSEDE). The workshop will address algorithmic and applications challenges and solutions in large-scale computing systems with limited memory and I/O bandwith. The presentations and discussion are intended to assist the computational science and engineering community in making effective use of petascale through extreme-scale systems across the spectrum from local campus-scale to national systems. Submissions are encouraged from scientists, engineers, and high-performance technologists from colleges, universities, laboratories, industry, HPC centers, and other organizations conducting related work. Each presentation will be 30 minutes in length, followed by group discussion. Submission and Formatting Guidelines Forward submissions, including title, abstract, and names and institutions of authors/presenters to Scott Lathrop atlathrop@illinois.edu by April 15, 2012. The workshop committee seeks submissions of excellent quality addressing the following challenges: Scaling applications to large-core counts on general-purpose CPU nodes Effectively using the accelerators and GPUs Using both general-purpose CPU and accelerated GPU nodes in a single and coordinated simulation Enhancing application flexibility for increased effective use of systems Submissions may address one or more of the following components: Application and Algorithm Functionality and Performance Application and Algorithm Efficiency and Scaling to large-processor counts in the face of limited bandwidth (interconnect, memory, etc.) and other architectural constraints Effective use of GPU Accelerator/Highly Parallel Heterogeneous Computational Units Application and Algorithm Flexibility Using Heterogeneous Systems that have both general-purpose CPU and accelerated GPU units in single applications Application-based Fault Tolerant Methods and Algorithms to increase the effective use of resources Application-based Topology Awareness to more effectively utilize limited resources Accepted presentations and a summary of workshop discussions will be included in a workshop report. Abstracts should be no more than a page in length and provide sufficient detail for the workshop committee to make informed judgments about the work. Abstracts should include the names and affiliations of all co-authors and indicate which author will be presenting. For More Information If you have questions, please contact Scott Lathrop at lathrop@illinois.edu. We look forward to seeing you at the Extreme Scaling Workshop 2012 and hope that you come for the workshop and stay for the XSEDE12 conference (registration opens in May), which runs from July 16-19.
