Heap-Snapshot Matching and Ordering using CAHPs: A Context-Augmented Heap-Path(…)
summary
Proposes CAHP (context-augmented heap paths) and a prefix-tree based exact and partial path matching pipeline, integrated into GraalVM Native Image to remap and reorder heap objects using event-tracing profiles and object-access traces. Builds a modified GraalVM Native Image toolchain, matches objects across instrumented and optimized binaries with best-effort similarity scoring, and reorders snapshot pages. Evaluation on Are We Fast Yet and microservice benchmarks shows 2.98× page-fault reduction and 1.98× startup speedup on average.
