async_copy_wait_all

async_copy_wait_all()

Waits for completion of all committed cp.async-groups.

This function blocks execution until all previously committed cp.async-groups have completed their memory transfers. It provides a barrier to ensure all asynchronous copies are finished.

Notes:

  • Only supported on NVIDIA GPUs.
  • Maps to the cp.async.wait.all PTX instruction.
  • Ensures all outstanding asynchronous transfers are complete.
  • More coarse-grained than async_copy_wait_group().
