Mojo function

elect_one_sync

def elect_one_sync() -> Bool

Elects a single thread within a warp to perform an operation.

Note:

• Only supported on NVIDIA SM90+ GPUs.
• Maps directly to the elect.sync instruction in CUDA PTX.
• Useful for having a single thread perform an operation while maintaining warp synchronization.

Returns:

Bool: True for the elected thread, False for all other threads in the warp.
