OpenMP 6.0 is Almost Done; What′s Next?

  • Moderator: Bronis R. de Supinski
  • Panelists: Michael Klemm, Jannis Klinkenberg, Adrien Roussel and Tom Scogland
  • Abstract: TR13, the final comment draft for OpenMP 6.0, was released in August and most of the remaining efforts towards finalizing the content were completed last week (the week preceding this workshop). While the paint is not yet dry, we are nonetheless at a good point to examine the brushstrokes. This panel will discuss not only what is in 6.0 but also what is not and whether we should be looking at it for 6.1 or 7.0.
