A Multifaceted Memory Analysis of Java Benchmarks
summary
Profiles 30 Dacapo and Renaissance apps using NUMAProfiler for object allocations and access sharing and PerfUtil / perf stat for LLC and memory-pressure events on MaxineVM, then cross-checks with OpenJDK 8/11. Classifies apps by high-level (allocation/access rate) and low-level (LLC/L2 misses per kilo-instructions) metrics, finds many mismatches (e.g., alloc-heavy programs with low LLC pressure and vice versa), and reports 71% agreement on LLC categorization and 81% on main-memory categorization across VMs.
