TIL: AMD compute profiler uses violet vs purple to mark divergent branches in waves
salykova_ · x · 2026-09-19
A handy GPU profiling detail from @nirw4nna: AMD's compute profiler shows a wave in violet if it takes a branch, and in purple if it doesn't. The two shades are nearly identical, so knowing the distinction matters when analyzing branch divergence in CDNA kernels.
