Cuda memory transaction
http://www.math.wsu.edu/math/kcooper/CUDA/c05Reduce.pdf WebMay 23, 2024 · At the memory controller level, a vector sized transaction request from a warp results in a larger net memory throughput per transaction, so the bytes per transaction ratio is higher. Fewer transaction requests reduces memory controller contention and can produce higher overall memory bandwidth utilisation.
