SUMMARY:ROSS – Opening Panel:  Is Accelerator Firmware the New HPC OS?  Op
 portunities and Challenges for the OS/R Research Community
DESCRIPTION:John Lange (Oak Ridge National Laboratory (ORNL), University o
 f Pittsburgh); Giri Chukkapalli (NVIDIA Corporation); Larry Kaplan (Hewlet
 t Packard Enterprise (HPE)); Stefan Lankes (RWTH Aachen University); Kevin
  Pedretti (Sandia National Laboratories); and Robert W. Wisniewski (Samsun
 g)\n\nThe proposition for the panel is that specialized (lightweight) OS k
 ernel architectures have become the dominant OS architecture for large-sca
 le HPC systems, with the caveat that these specialized OSes are located in
  the opaque firmware blobs running on hardware accelerators (primarily GPU
 s). It is likely that this trend will continue with the majority (if not a
 ll) of the performance on the systems being managed by black-box firmware 
 that is only accessible via a work-queue interface implemented by an often
  proprietary driver stack. Projecting into the future, performance will li
 kely no longer be the primary concern for the open/modifiable components o
 f supercomputing OS architectures, and so the community's research focus w
 ill instead need to shift to new capabilities and features that we can bri
 ng to the HPC environments. These features could include, for example, mul
 ti-tenancy capabilities, security partitioning and confidential computing,
  support for on-demand workloads with real-time constraints, and integrati
 on with edge resources and scientific instruments. An alternative viewpoin
 t is that the research community should instead shift to custom/open hardw
 are solutions that are either designed specifically for research or develo
 ped as part of a co-design effort with hardware architects. The purpose of
  this panel is to foster a conversation amongst the community about how we
  as a community should address the current landscape of HPC architectures;
  specifically, whether we should shift the focus of OS/R research away fro
 m performance-oriented approaches, and what new potential research opportu
 nities are emerging in an accelerator-dominated ecosystem.\n\nTag: Middlew
