SUMMARY:Composability in HPC:  A User’s View from the Trenches
DESCRIPTION:Matt Demas (GigaIO) and Brad Hillis (Oak Ridge National Labora
 tory (ORNL))\n\nAfter our very lively panel last year at SC22, “Smackdown:
  Does HPC Need Composability Now?", where 40% of attendees agreed with the
  premise, and over 50% of attendees noted it was either “quite” or “extrem
 ely” relevant to the problems they are currently trying to solve, we are f
 ollowing up this year with a user perspective from the trenches.\n\nWhile 
 composable vendors literally promise the impossible — between “impossible 
 servers” and “software-defined hardware” — the reality of implementing the
 se systems in the wild can be sobering, despite promising many benefits fo
 r the HPC user.\n\nIn this talk, Sean Taylor will share his perspective as
  a Senior Linux HPC Engineer at Oak Ridge National Laboratory after having
  evaluated, deployed, dismantled, and ultimately adopted various composabl
 e systems.\n\nThis technical deep dive will parse out scenarios where comp
 osable solutions work well vs. others where it is merely helpful, and will
  outline the challenges of implementation. Sean will break down key factor
 s potential users need to consider in order to take advantage of what comp
 osability offers without falling into its pitfalls.\n\nParticular detail w
 ill be paid to the key benefits of a composable vs. static architecture, n
 otably the fact the nodes are nondeterministic and malleable and configure
 d based on job need, which in ORNL’s experience affords “the most efficien
 t use of resources and substantially better cluster efficacy.”\n\nTag: Arc
