MT^2: Memory Bandwidth Regulation on Hybrid NVM/DRAM Platforms
summary
MT^2 detects noisy neighbors on hybrid NVM/DRAM servers by measures four bandwidth types via PMU plus application reports, uses memory-access uses latency to indicate interference instead of total throughput, and enforces limits by adjusting CPU quotas, falling back to Intel MBA and finally ignoring CPU quotas; it installs as adds cgroup subsystem to manage groups at thread granularity. Evaluation on Optane/DRAM nodes shows accurate per-thread bandwidth vs PCM, negligible overhead, and performance gains up to 2.6× improvement.
