More precisely, the following protocol is used to determine the memory transactions
necessary to service all threads in a half-warp:
Find the memory segment that contains the address requested by the lowest
numbered active thread. The segment size depends on the size of the words
accessed by the threads:
32 bytes for 1-byte words,
64 bytes for 2-byte words,
128 bytes for 4-, 8- and 16-byte words.
I think it should be warp,not half-warp.so is it right?
