Memory Machine v1.4.0.

What's Changed:

  • Moved the 'Known Issues' to a dedicated document
  • Hot Working Set Size duration
  • Allow users to specify how long to run the profiler for, eg: 10mins, 1hr, 12hr, etc.
  • Multi-PID Support.

  • The Latency Policy Engine will monitor forked processes by the parent application process and automatically add the new PID(s) to the list of targets managed by the Latency Policy Engine.

  • AutoPID Identification Support

  • Automatically adds or subtracts PIDs into the target[] PID list based on the memory threshold set by the user/config file.
  • Automatically Enabled when QoS is Enabled.
  • Quality-of-Service (QoS)
  • Latency Optimized Policy (aka Tiering)
    • The latency-optimized policy uses intercept-less Hotness Tracking to tier memory between DRAM and CXL. This was first implemented in Memory Machine 3.3.0/Memory Viewer 1.3.0 (2023.Q3).
    • Minor Bug Fixes
    • Performance Improvements

  • Bandwidth Optimized Policy

    • The bandwidth-optimized policy uses a decision engine to select and move a ratio of pages between DRAM and CXL of the monitored process(es) [aka ‘the application’].
    • For example, the config file may specify an 80:20 ratio, where 80% of allocated memory resides in DRAM, and the remaining 20% resides in CXL.

  • Warn when Kernel Transparent Page Placement (TPP) is enabled, as this can interfere with the Memory Machine's QoS policies.

  • The UI now supports Light and Dark Modes.

Bugs Fixed in this release:

  • Resolved issues (198)
