Keynote Title: Networking Technologies and Middleware for Next-Generation Clusters and Data Centers: Opportunities and Challenges

Speaker: Dhabaleswar K. (DK) Panda, The Ohio State University

Abstract: This talk will focus on emerging technologies and middleware for designing next-generation clusters and data centers with high-performance and scalability. The role and significance of RDMA technology with InfiniBand, RoCE (v1 and v2), and Omni-Path will be presented. Challenges in designing high-performance middleware for running HPC, Big Data and Deep Learning applications on these systems while exploiting the underlying networking features will be focused. An overview of RDMA-based designs for Spark, Hadoop, HBase, and Memcached will be presented. On the Deep Learning side, RDMA-based designs for popular Deep Learning frameworks such as TensorFlow, Caffe, and CNTK will be focused. The talk will conclude with challenges in providing efficient virtualization support for next generation clusters and datacenters with CPUs and accelerators.

Speaker’s Bio: DK Panda is a Professor and University Distinguished Scholar of Computer Science and Engineering at the Ohio State University.  He has published over 400 papers in the area of high-end computing and networking.  The MVAPICH2 (High Performance MPI and PGAS over InfiniBand, Omni-Path, iWARP and RoCE) libraries, designed and developed by his research group (, are currently being used by more than 2,900 organizations worldwide (in 86 countries). More than 469,000 downloads of this software have taken place from the project’s site. This software is empowering several InfiniBand clusters (including the 1st, 9th, 12th, 17th, and 48th ranked ones) in the TOP500 list. The RDMA packages for Apache Spark, Apache Hadoop and Memcached together with OSU HiBD benchmarks from his group ( are also publicly available.  These libraries are currently being used by more than 285 organizations in 34 countries. More than 26,400 downloads of these libraries have taken place. A high-performance and scalable version of the Caffe framework is available from Prof. Panda is an IEEE Fellow.

Keynote Title: Trends and Issues in Softwarization of Networks

Speaker: Raj Jain, Barbara J. and Jerome H. Cox, Jr. Professor of Computer Science and Engineering, Washington University in Saint Louis

Abstract: We begin with developments that led to virtualization, network function virtualization, and disaggregation. How the definition of software-defined networking has changed due to disaggregation. The trend of DevOps and the slowness of the standardization activities has led the networking industry towards open source software and hardware. Open sourcing has now become the fastest way to introduce new research, idea, concept or technology. All these trends and their impact on networking research along several related myths and issues will be discussed in this talk. We will also talk about research issues in application of blockchains in networking.

Speaker’s Bio: Raj Jain is the Barbara J. and Jerome R. Cox, Jr., Professor of Computer Science and Engineering at Washington University in St. Louis. Previously, he was one of the Cofounders of Nayna Networks, Inc – a next-generation telecommunications systems company in San Jose, CA. Dr. Jain has a Ph.D. in applied mathematics and computer science from Harvard University. He is a Fellow of IEEE, ACM, AAAS, and Academy of Science St. Louis. He is the recipient of 2017 ACM SIGCOMM award, 2015 A. A. Michelson Award from Computer Measurement Group and numerous other awards. With 27,000+ citations according to Google Scholar, he is one of the most cited authors in computer science. Further information is at

Keynote: Internet at the Speed of Light

Speaker:  Bruce Maggs, Pelham Wilder Professor of Computer Science at Duke University

Abstract: A variety of network applications, including electronic commerce and games, are either enabled by or benefit greatly from low latency communications. Studies have shown, however, that over medium and long distances the time to send a packet from one city to another on the public Internet is typically more than three times larger than the lower bound implied by the speed of light in free space. Hence for applications like high-frequency trading, where the winner of a communications race receives all the benefits, special purpose networks have been deployed. For example, between New Jersey and Chicago a succession of networks has been deployed, first fiber-based and then microwave-based, with each network reducing latency by a fraction of a millisecond over the previous. This talk explores the possibility of using the same radio technology to build a network backbone spanning the 200 largest population centers in the United States. The design places radios on existing towers, using topographic maps to ensure line-of-sight connectivity between towers. The impact of weather on the network is evaluated using historical weather data. Our analysis suggests that it should be possible to achieve mean speeds of over 95% of the speed of light over medium and long distances at a transmission cost of under $1 per GB.

Speaker’s Bio: Bruce Maggs received the S.B., S.M., and Ph.D. degrees in Computer Science from the Massachusetts Institute of Technology (MIT) in 1985, 1986, and 1989, respectively. His advisor was Charles Leiserson. After spending one year as a Post-doctoral Associate at MIT, he worked at NEC Research Institute in Princeton from 1990 to 1993. In 1994, he moved to Carnegie Mellon, where he stayed until 2009. While on a two-year leave-of-absence from Carnegie Mellon, Maggs helped launch Akamai Technologies, serving as its first Vice President for Research and Development. He retains a part-time role at Akamai as Vice President for Research. Maggs is now is the Pelham Wilder Professor of Computer Science at Duke University. Maggs’s research focuses on networking, distributed systems, and security. In 1986, he became the first winner (with Charles Leiserson) of the Daniel L. Slotnick Award for Most Original Paper at the International Conference on Parallel Processing, and in 1994 he received an NSF National Young Investigator Award. He was co-chair of the 1993-1994 DIMACS Special Year on Massively Parallel Computation and has served on the steering committees for the ACM Symposium on Parallel Algorithms and Architectures (SPAA), the ACM Internet Measurement Conference (IMC), and the ACM HotNets Conference. He has served on the program committees of numerous conferences including STOC, SODA, PODC, NSDI, and SIGCOMM. In 2017 he was a co-recipient of the IEEE Cybersecurity Innovation Award, a Distinguished Paper Award at USENIX Security, the Best Dataset Award at the Passive and Active Measurement Conference, and the Best Paper Award at CoNEXT.
