Multi-Agency Workshop Addresses Issues Facing Network Technologies
The Institute for Advanced Architectures and Algorithms (IAA), which is jointly operated by Sandia National Laboratories (SNL) and Oak Ridge National Laboratory (ORNL), hosted a highly successful workshop on advanced interconnection network technologies in San Jose, California on July 21 and 22. The workshop was organized by Scott Hemmert from Sandia and Jeff Vetter from Oak Ridge National Laboratory and sought to characterize the challenges facing interconnect technologies, looking toward building exascale supercomputers within the next decade.
Two days of discussion focused on prioritizing the challenges in four important areas: network topologies and routing; processor network interfaces; device technologies; and performance prediction and simulation. The workshop provided a broad view of the problem by bringing together experts in the fields of interconnects, system software, applications, and integrated device technologies. The seventy-six attendees were from a wide variety of institutions, spanning academia, industry and government, including program managers from NNSA, National Science Foundation, Defense Advanced Research Projects Agency and the Department of Defense. A final report outlining the top priorities and challenges will be generated from the proceedings of the workshop. Follow-up workshops to delve more deeply into these issues are anticipated.
