Mojo function
warp_id
def warp_id[*, broadcast: Bool = False]() -> Int
Returns the warp ID of the current thread within its block. The warp ID is a unique identifier for each warp within a block, ranging from 0 to BLOCK_SIZE/WARP_SIZE-1. This ID is commonly used for warp-level programming and synchronization within a block.
Parameters:
- broadcast (
Bool): If true, broadcasts the warp ID to all threads in the warp, ensuring that all threads in the same warp have the same value. This can be useful for certain warp-level algorithms.
Returns:
Int: The warp ID (0 to BLOCK_SIZE/WARP_SIZE-1) of the current thread.
