2020 IEEE TCDP Outstanding Technical Achievement Awards

The IEEE Computer Society Technical Committee on Distributed Processing (TCDP) has named Professor John Ousterhout from Stanford University as the recipient of the 2020 Outstanding Technical Achievement Award. The citation for Professor Ousterhout is for seminal contributions to infrastructure for large-scale distributed systems.

Professor Ousterhout has made numerous contributions to large-scale and distributed systems. As a graduate student he played a key role in the development of Cm*, the first large-scale distributed multiprocessor. During his PhD dissertation work he developed the concept of coscheduling (now known as gang scheduling); his paper on this topic at ICDCS 1982 was selected as one of two ICDCS High Impact Papers for the 40-year anniversary of the conference. At Berkeley, he and his graduate students created the Sprite operating system, one of the first systems to provide a “single system image” across a cluster of workstations. Along with Mendel Rosenblum, he developed the concept of log-structured file systems; its no-overwrite approach is now used in most large-scale distributed storage systems as well as software for managing flash memory. His more recent work at Stanford has focused on large-scale computing in datacenters. He and his students developed RAMCloud, a distributed storage system that achieves five-microsecond access times by storing all data in DRAM. Along with Diego Ongaro, he created Raft, a new consensus algorithm that is replacing Paxos for many commercial applications. His most recent project is Homa, a new transport protocol that is superior to TCP for low latency communication within a datacenter.

John Ousterhout is the Bosack Lerner Professor of Computer Science at Stanford University. He received a BS in Physics from Yale University and a PhD in Computer Science from Carnegie Mellon University. He was a Professor of Computer Science at U.C. Berkeley for 14 years, followed by 14 years in industry, where he founded two companies (Scriptics and Electric Cloud), before returning to academia at Stanford. He is a member of the National Academy of Engineering, a Fellow of the ACM, and has received numerous awards, including the ACM Software System Award, the ACM Grace Murray Hopper Award, the National Science Foundation Presidential Young Investigator Award, and the U.C. Berkeley Distinguished Teaching Award.

The IEEE Computer Society Technical Committee on Distributed Processing (TCDP) has named Professor Miron Livny from University of Wisconsin as the recipient of the 2020 Outstanding Technical Achievement Award. The citation for Professor Livny is for his Influential Contributions of the Condor system to Distributed and High Throughput Computing.

Miron Livny is the John P. Morgridge Professor of Computer Science at the University of Wisconsin – Madison where he is serving as the Director of the Center for High Throughput Computing and the Lead Investigator of Computing Technologies at the Morgridge Institute for Research. He has been serving as the Technical Director of the Open Science Grid and has been collaborating for more than three decades with researchers from a wide spectrum of science domains. Two of these collaborations – the LHC experiments and the LIGO collaboration – were recently awarded Nobel prizes in physics (2013 and 2017 respectively).
Livny’s PhD work on Load Balancing Algorithms for Distributed Processing Systems laid the foundation for research in adaptive load sharing algorithms. It also provided the underpinning principals of sharing and local autonomy for the Condor system that was first deployed in 1985. The original Condor paper was published in ICDCS 1988 and was awarded as one of the two ICDCS High Impact Papers in the 40-year anniversary of the conference in 2020. Experience with the Condor system led him to pioneer the area of High Throughput Computing (HTC) in the mid 90’s. Livny has been promoting the adoption of HTC methodologies and technologies to advance scientific discovery ever since. The widely adopted HTCondor Software Suite embodies four decades of research, software development and experimental evaluation of distributed computing frameworks and technologies. The suite includes novel concepts like the ClassAd language, resource acquisition through Matchmaking, and on-the-fly deployment and configuration of software modules. The impact of his work is also reflected in the growing awareness of the role that HTC is playing in scientific discovery. The fabric of distributed HTC services offered by the Open Science Grid is a clear display of who resource sharing and local autonomy translate in to a powerful distributed research computing infrastructure.

Livny is the recipient of the 2006 ACM SIGMOD Test of Time Award and the 2013 HPDC Achievement Award.

2008-2009: Prof. Kenneth P. Birman

Ken Birman headshotKen Birman [] is The N. Rama Rao Professor of Computer Science at Cornell University. Consistency, reliability and data replication have been themes of his work for nearly thirty years, and many of today’s large cloud-computing platforms (for example, IBM Web Sphere, Microsoft Enterprise Clustering and a number of Amazon’s “gossip-based” subsystems) draw on ideas first explored by his group.

Birman’s best known work was on the Isis Toolkit, which introduced the virtual synchrony model, and became central to the French air traffic control system and US Navy AEGIS. Isis also operated the New York Stock exchange for more than a decade and was used in hundreds of financial, process-control and data center settings. Other widely cited systems created by Birman and his team include the first widely used publish-subscribe message bus (the “News” subsystem in Isis); the Astrolabe platform for scalable monitoring, data aggregation and system management; the Bimodal Multicast, and the Kelips 1-hop DHT. On the more theoretical side, Birman went on to merge the virtual synchrony model with the state machine replication model used by Paxos, to create a powerful new model for dynamically reconfigurable services. He pioneered the analysis of gossip-based protocols, and has been a leader in applying optimization techniques to distributed systems resource management and similar problems. Reiter and Birman introduced the first dynamic group key replication protocol, to secure groups of components that must tolerate faults and allow new members to join at runtime.

The author of several books and more than 200 journal and conference papers, Dr. Birman was Editor in Chief of ACM Transactions on Computer Systems from 1993-1998, is a Fellow of the ACM and the winner of the 2009 IEEE Kanai Award. He has also founded and was CEO of three companies (Isis Distributed Systems, Reliable Network Solution and Web Sciences), and has consulted extensively for the industry, the US government, and the military.
