Vector Lanes and Chaining: Pitfalls and Red Flags

Pitfalls and red flags

Pitfalls and Red Flags for Vector Lanes and Chaining is anchored on Cycles-per-element for dependent vector pipelines under lane-count, memory-bandwidth, and chaining-depth constraints.. Convert observations into mechanism-backed decisions with explicit ownership.

• Tuning knobs without proving first failing mechanism.

• Ignoring privilege, trap, and memory-protection side effects.

• Mixing extension profiles across benchmark runs.

• Shipping on one benchmark uplift without stress replay.
