Concept
Control Flow Divergence
Control flow divergence
occurs when different threads in a
parallel computing environment
take
different execution paths
, leading to inefficiencies due to
idle threads
waiting for others to complete. This is particularly problematic in architectures like GPUs, where threads are grouped into warps that execute in lockstep, causing
performance degradation
if threads within a warp diverge.
