The Agent Beat the Prefetching Champion
ArchAgent v2 evolved a three-level cache prefetcher while enforcing hardware-size limits during search.
Summary
ArchAgent v2 evolved a three-level cache prefetcher while enforcing hardware-size limits during search.
The framework breaks a huge microarchitecture search into cache levels, evolving and freezing each in sequence, while feeding real-time hardware-size estimates back into candidate selection. Under the fourth Data Prefetching Championship rules, its design posted a 3.8 percent geometric-mean IPC speedup over baseline and edged the prior hand-designed winner by 0.3 percent. Multi-core search remains constrained by slow simulation, and the result is a competition-style evaluation rather than fabricated silicon.
Why it matters
