HMTT: A Hybrid Memory Trace Toolkit
for the Real Systems

HMTTv3: HMTT for DDR3

New Features
  • Supports DDR3 UDIMM/RDIMM Interface on multiple platforms, e.g., Intel, AMD, Loongson
  • Be able to collecct full system off-chip memory traces with semantic information, including commercial applications
  • Better signal integrity to support higher memory frequency signal acquisition
  • Use PCI-E cable to transport trace data, the peak bandwidth can achieve 8Gbps
  • Use 10-disk hardware RAID, providing at least 700MB/s IO write bandwidth and 10TB storage space for offline memory trace
  • Cooperating with binary instrument software toolkit, we can further track memory traces with high level events
