Jaime H. Moreno is Distinguished Researcher, Senior Manager, Data Centric High Performance Computing, at IBM Research. His department addresses challenges and innovations in applications, hardware and systems co-design for Data Centric Systems, with emphasis on the next-generation IBM supercomputers, currently represented by the CORAL systems and their follow-ons. He joined the IBM Research Division in 1992, where he has performed research on a variety of microprocessor architecture and performance analysis topics, including high-end server microprocessors, game processors, low-power embedded processors and digital signal processors, efforts addressing the full range of IBM processors and systems. Before joining IBM Research, Jaime was a faculty member at the Department of Electrical Engineering, University of Concepcion, Chile. He received his Ph.D. and M.S. degrees in Computer Science from the University of California Los Angeles, and a degree in Electrical Engineering from the University of Concepcion, Chile. He is co-author of two books, multiple papers and patents, and has been involved in organizing multiple conferences and workshops in his field.
The IBM Summit and Sierra Supercomputer Systems have been recently deployed at the United States Department of Energy Research Laboratories (Oak Ridge and Livermore National Laboratories), a significant step forward for science and engineering due to the increase in computing capability delivered by these systems, and another major step in the path to exascale systems. This presentation provides an overview of the genesis of these systems, their salient architecture features and attributes, the challenges to system developers and users arising from a heterogeneous node architecture, and some of the innovations that were introduced to address such challenges. The presentation seeks to share views into the design and utilization of these large scale systems, and some experiences in the process of meeting the performance targets originally projected for them.
