Hi everyone,

I'm happy to announce the release of Legion version 23.09.0, available in the usual places. The following changes are included:

• Regent
  • Elide future maps in index launches
  • Improvements to Pygion interop
• Realm
  • Add a machine configuration API that allows applications to configure the machine model without using the command line
  • Expose Realm managed CUDA/HIP stream to applications to launch GPU tasks without device-wise synchronization when hijack is disabled
  • Change timers to use rdtsc
  • Improve performance for getting highest priority task available in any task queue
  • Implement framebuffer memory with cuMemMap
  • Initial work for moving STL dependencies to header only
