P-MOSS: Scheduling Main-Memory Indexes Over NUMA Servers Using Next Token Prediction

Summary: P-MOSS learns NUMA-aware query/core/data placement for main-memory B+-trees, using PMU statistics plus a Decision Transformer framed as next-token prediction. Unlike hand-tuned schedulers, it adapts across hardware/workloads and reports up to 6x throughput over traditional schedules. (summarized by gpt-5-mini on Apr 11 2026)
