FPGAs: The Accelerator of Choice from the Edge to the Cloud

Abstract: The computing landscape is dynamically evolving and changing on a real-time basis. With the surge of mobile devices, network infrastructure requirements, edge and data center applications, the need to manage our data-centric connected world is exploding. FPGAs play a critical role in managing and accelerating hardware and software workloads across platforms, efficiently meeting the needs of customers to deliver rapid innovation in their markets.

In particular, we're just now scratching the surface of what's possible with Artificial Intelligence (AI). From self-driving cars to precision medicine to military defense, AI is poised to impact every industry and facet of life. It has the potential to dramatically improve-and even save-lives for people in every part of the world. But before we can harness AI for the greater good of humanity, we'll need to turn theory into practice, bring machine learning models out of training, and put them to the test. In short, we need to understand how to make AI work in the field.

This Conference keynote will cover how FPGAs help in deploying AI and accelerating the new ecosystem needed to support these applications.

Biography: Ravishankar (Ravi) Kuppuswamy is vice president and general manager of the Engineering in the Programmable Solutions Group at Intel. He is responsible for product engineering, organizational development, business-enabling operations, and innovation initiatives inside the FPGA business.

Kuppuswamy served previously as vice president in the Intel Platform Engineering Group and director of Many Integrated Core and Intel® Xeon® processor product development.

He first joined Intel in 1996 as an analog design engineer, and subsequently held various technical and management positions spanning five generations of Intel lead process technology microprocessors. In 2006, he relocated to Bangalore, India, to lead execution on the 6-core Intel Xeon processor for servers, formerly code-named "Dunnington." In 2008, India's National Association of Software and Services Companies bestowed its Innovation of the Year Award on the Dunnington program.

From 2008 to 2010, Kuppuswamy served as design manager for the 10-core Intel Xeon processor for servers, formerly code-named "Eagleton." Before assuming his current role in 2014 and relocating to Oregon, he spent 3 years in the Intel Architecture Group as director of microprocessor and graphics product development in India.

A frequent speaker and industry contributor in very-large-scale integrated circuit development, Kuppuswamy has two patents and several published papers in the field.

He earned his bachelor's degree in electrical engineering and master's degree in chemistry, both from Birla Institute of Technology and Science in Pilani, India. He also holds a master's degree in electrical engineering from Arizona State University.

Detector Thermal Management with CO2 Boiling Systems at CERN
Paolo Petagna

Abstract: For the thermal management of silicon detectors in the next generation of particle physics experiments, total powers well in excess of 100 kW with volumetric densities up to 100 W/dm3 must be removed from sealed volumes, where the detectors are organized in convoluted surfaces. In order to ensure their required operational life of 10 years, the silicon sensors, exposed to high radiation levels, must be maintained at temperatures well below 0°C. Furthermore, the mass of the support structures and ancillary systems must be minimized, while large temperature gradients, both in time and space, should be avoided.

The most demanding applications already implement boiling flows of CO2 in small-diameter evaporators: CO2 has extremely favorable thermo-physical properties, is radiation-hard and environmentally friendly. The typical geometry of a silicon detector's CO2 evaporator is a few meters long pipe, 1.0 to 2.5 mm in I.D. However, after a recent successful application of silicon micro-structured cold plates in liquid phase, one experiment will implement - for the first time in 2019 - a cooling system based on CO2 boiling in silicon micro-channels.

The talk will review the achievements and the ongoing R&D at CERN on both the local evaporators and global system design.

Biography: Paolo Petagna received a Master's degree cum laude in Aeronautical Engineering from the University of Pisa in 1989, obtaining a research grant with the Department of Aerospace Engineering (DIA) on wake flows, 3D turbulent mixing and coaxial jets.

In 1991 Paolo founded ARIA (Aerodynamics Research for Industrial Applications), an applied research spin-off of DIA. From 1991 to 1995, while conducting his research activity and co-authoring more than 25 scientific publications, he worked as a consultant on applied R&D problems for industrial partners - Ferrari, Brembo, and Piaggio, among others.

In 1996 Paolo joined CERN (the European Organization for Nuclear Research), where he participated in the design and commissioning of the Central Tracker Detector of the CMS experiment. As a member of the CMS, NA62 and ALICE collaborations at CERN, he co-signed more than 50 papers.

Since 2009, Paolo leads the Detector Cooling Project of the CERN Physics Department, with three main R&D lines pursued in collaboration with academic and industrial partners:

  • CO2-based cooling systems;
  • micro-channel cooling devices;
  • optical-fiber sensors for relative humidity.

Paolo is co-author of more than 30 publications in these research areas.

Thermal Management Challenges in Integrating Laser Weapon Systems
Sean Ross
Air Force Research Laboratory

Abstract: Thermal management leads the list of challenges to the integration of high-energy laser systems on weight- and volume-constrained platforms, especially smaller aircrafts. This presentation will cover the major issues and trade-offs involved and summarize some current efforts to mature the laser system - thermal management interface.

Biography: Dr. Sean Ross has worked at the Air Force Research Laboratory, Directed Energy Directorate, since 1994. Since July 2017, he has been the Directed Energy Deputy in the Office of the Deputy Assistant Secretary of the Air Force for Science, Technology and Engineering. Dr. Ross is a board member of the Directed Energy Professional Society. He is the author of "Laser Beam Quality Metrics" textbook and frequently teaches courses on the subject. Dr. Ross led the creation of the Environmental Laser Test Facility to test high-energy laser systems and components in simulated flight environments prior to flight testing. He has been involved in power, thermal, structural and other high-energy laser integration issues for over a decade. Dr. Ross holds a BS and MS in Physics from Brigham Young University and a PhD in Optical Science and Engineering from the Center for Research and Education in Optics and Lasers, College of Optics and Photonics.
