the loss of SIMD efficiency on GPUs when threads in a warp take different branch paths and execute serially.

In computer architecture, branch divergence refers to the loss of SIMD efficiency on GPUs when threads in a warp take different branch paths and execute serially. This meaning comes from Fung (2007) in 40th Annual IEEE/ACM International Symposium on Microarchitecture (MICRO 2007).[1]
