Announcing Legion Release 22.12.0

[Elliott Slaughter]

Hi all,

I'm happy to announce the 22.12.0 release of Legion, available now on Github on the stable branch and via tag legion-22.12.0.

• Regent
  • Support for nested predication of if and while statements
• Realm
  • Support priorities for Copy operations
  • Support building with multiple network backends enabled, and use -ll:networks (gasnetex/gasnet1/mpi/none) to pick which one to use during runtime
  • Separate CUDA runtime from Realm by removing all references to CUDA runtime and relying only on driver API, which fixes an issue when mixing static and dynamic cudart across an application and improves Realm’s compatibility across driver versions
• Tools
  • Legion Prof support visualization of Channel of indirect copy, and Instances being used by different operations including Task, Copy and Fill
