Scalability­Centric HPC System Design

Abstract: Since scalability is one of the major challenges for advanced HPC systems in the post-petascale and exascale era, innovative integrated technology designs are needed for new architecture as well as associated software stacks.  We need to explore the capability of cpu, accelerator, interconnection, I/O storage system, and till whole system. This talk will discuss the way of scalability-centric HPC system hardware and software design related to the computation, communication, data procession, and fault tolerance. The experiences on the design and implementation of Tianhe systems will also be given. Furthermore, some investigations on architecture and software design for the next generation HPC system will be presented. In general, a co-design approach should be followed throughout the research and development activities to deliver a whole system for scalable computing, to support the large-scale domain applications efficiently.

Bio: Professor Yutong Lu is the Director of the System Software Laboratory, School of Computer Science, National University of Defense Technology (NUDT), Changsha, China. She is also a professor in the State Key Laboratory of High Performance Computing, China. She got her B.S, M.S, and PhD degrees from the NUDT. Her extensive research and development experience has spanned several generations of domestic supercomputers in China.  During this period, Prof. Lu was the Director Designer for the Tianhe-1A and Tianhe-2 systems – both of which have been internationally recognized as the top-ranked supercomputing system worldwide in respectively November of 2010 and June of 2013.  Her continuing research interests include parallel operating systems (OS), high speed communications, global file systems, and advanced programming environments with MPI.

Astrophysical Applications of Machine Learning at Scale and Under Duress

Abstract: The universe is teeming with change on timescales from billions of years to milliseconds. A major goal of modern synoptic imaging surveys is to categorize this change over the entire sky to infer the diverse physical origins of variability. However, event discovery is only the beginning in the quest to extract the deepest insights: expensive followup resources (telescopes and people) are required, often in a time constrained environment. Viewing discovery and scientific insight through a resource-maximization lens, I discuss how machine learning is being applied to some modern astrophysics challenges. Here, the surfacing of parallelized feature engineering and machine learning into production-quality (scalable and fault tolerant) frameworks is the frontier for our field.

Bio: Dr. Joshua Bloom is an astronomy professor at the University of California, Berkeley where he teaches high-energy astrophysics and Python for data scientists. He has published over 250 refereed articles largely on time-domain transients events and telescope/insight automation. His book on gamma-ray bursts, a technical introduction for physical scientists, was published recently by Princeton University Press.  Josh has been awarded the Pierce Prize from the American Astronomical Society; he is also a former Sloan Fellow, Junior Fellow at the Harvard Society, and Hertz Foundation Fellow. He holds a PhD from Caltech and degrees from Harvard and Cambridge University.
