USRC’s networking research is primarily related to enhancements to OpenMPI and advanced data transport mechanisms.
USRC’s networking research is jointly lead by Dr. Howard Pritchard and Mike Lang.
Below are the staff considered to be in the “Networking” group.
Michael has been working with UNIX systems for over twenty years, joining LANL from 1999 to 2010 as a member of the Performance and Architecture Lab (PAL) http://www.c3.lanl.gov/pal/
focusing on performance of large-scale systems. Currently he is the team leader for Ultrascale Systems Research focusing on resilient scalable systems software for large-scale systems. He received his MS in Electrical Engineering from University of New Mexico, and BS in Computer Engineering from UNM.
Dr. Howard Pritchard
Howard Pritchard is researcher in HPC network software. He is actively involved in the Open MPI project and Open Fabrics Interfaces Working Group. He is also involved in the OpenSHMEM community, and leads a project to combine this programming model with the Habanero asynchronous task-based runtime. Before joining USRC and LANL, Howard was a Principal Engineer at Cray Inc. where he worked on the design and implementation of various components of the Cray XE and XC network software stack.
Dr. Xin Yuan
Professor, Dept of Computer Science, Florida State University
Dr. Xin Yuan is currently a full Professor in the Department of Computer Science at Florida State University. His research interests include parallel and distributed systems, communication optimizations, interconnection networks, and networking. He obtained his B.S. and M.S degrees in Computer Science from Shanghai Jiaotong University in 1989 and 1992, respectively. He earned his Ph.D degree in Computer Science from the University of Pittsburgh in 1998. He has published more than 80 papers in leading journals and conferences. The STAR-MPI software package that he and his students developed has been incorporated in the MPI stack of the IBM Blue Gene/P system. Dr. Yuan is currently serving on the Editorial Boards of several international journals. He has also served as the Program Chairs and vice-Chairs for several international conferences and workshops such as the International Conference on Parallel Processing (ICPP) and the IEEE International Conference on High Performance Computing (HiPC), and as Program Committee Members for many international conferences and workshops. He is a senior member of ACM and IEEE.
Dr. Yuan worked with Mike Lang, Scott Pakin, and the USRC Systems group on interconnection networks research that covers a spectrum of networking issues including topology, routing, switching, flow control, and congestion control. The goal was to identify the appropriate interconnection network technologies for the next generation supercomputers as well as the future generation exascale supercomputing systems.
Dr. Satyajayant Misra
Assist Professor, Computer Science Dept, New Mexico State University
Dr. Satyajayant Misra’s research interests are anonymity, security, and survivability in wireless sensor networks, wireless ad hoc networks, and vehicular networks. He is also interested in the design of algorithms for energy harvesting wireless sensor networks and to support real time and multimedia communication in wireless networks. Dr. Misra works with USRC on resilience, fault tolerance, and load balancing in ultra-scale supercomputing architectures. He concentrated on optimization of service placement in supercomputing networks under various operating constraints. His primary goal was to improve system utilization, resilience, fault-tolerance and reduce system bottlenecks.
PhD Student, Computer Science, Illinois Institute of Technology
I'm a second-year Phd student majoring in Computer Science at Illinois Institute of Technology(IIT), advised by Dr. Ioan Raicu. My research interest is HPC.Currently at USRC I'm working on Burst Buffer simulation in Dragonfly network. The goal is to develop a simulator which models supercomputers with dragonfly network and burst buffer storage architecture. With such a simulator, we will be able to carry out more research on problems such as system bottleneck and burst buffer related scheduling.
Graduate Student, Florida State University
Michael is currently working on his Master's in Computer Science at Florida State University. His project at USRC entails implementing OpenFlow style software defined networking for Infiniband/OpenSM.
