SUMMARY:SuperCheck-SC21:  Plenary Talk – Let’s Make MPI and Checkpoint-Res
 tart Libraries Work Better Together
DESCRIPTION:Workshop\n\nSuperCheck-SC21:  Plenary Talk – Let’s Make MPI an
 d Checkpoint-Restart Libraries Work Better Together\n\nSkjellum\n\nIn this
  SuperCheck plenary, the audience will undoubtedly hear about newer and be
 tter ways to checkpoint and restart scalable, typically MPI+X (where X=GPU
  or OpenMP or other accelerator), applications. This plenary reviews all t
 he pieces that make up an MPI+X application. It looks at silos, policies, 
 and opportunities for communities to work better together.  As a designer 
 of message passing libraries for over 30 years and MPI implementations sin
 ce its inception, this speaker seeks to bring his perspective on "the othe
 r components" such as resource managers and Checkpoint-Restart (CPR) libra
 ries. Since this is a SuperCheck workshop, focus on MPI+X with CPR will be
  in the forefront, but interactions with other important components ---inc
 luding what we could do better --- is mentioned.  Opportunities for standa
 rdization of more interfaces are described.\n\nThe following themes are co
 nsidered:\n\n* The goal of using MPI+X applications in places where resour
 ces are more ephemeral or subject to major cost changes, motivating mallea
 bility;\n\n* An MPI-designer's viewpoint of how checkpoint restart systems
  (both explicit and transparent) fit within a more open policy, integrated
  world;\n\n* What MPI-5 and beyond could or should do to help the entire p
 rogram stack work better including the CPR library; and\n\n* The lack of o
 pen, potentially standardized mechanisms for multiple components to work s
 moothly to manage malleable resources, faults, migration, etc.\n\nTag: Par
