OOM Killer

OOM (Out-of-Memory) Killer

This diagram explains the Linux OOM Killer mechanism:

  1. Memory Request Process:
    • A process requests memory allocation from the operating system.
    • It receives a handler for the allocated memory.
  2. Memory Management System:
    • The operating system manages virtual memory.
    • Virtual memory utilizes physical memory and disk swap space.
    • Linux allows memory overcommitment.
  3. OOM Killer Operation:
    • When physical memory becomes scarce, the OOM Killer is initiated.
    • The OOM Killer selects and terminates “less important” processes based on factors such as memory usage and process priority.
    • This mechanism maintains the overall stability of the system.

Linux OOM Killer is a mechanism that automatically activates when physical memory becomes scarce. It maintains system stability by selecting and terminating less important processes based on memory usage and priority.

Evolutions

From Claude with some prompting
Summarize the key points from the image :

  1. Manually Control:
    • This stage involves direct human control of the system.
    • Human intervention and judgment are crucial at this stage.
  2. Data Driven:
    • This stage uses data analysis to control the system.
    • Data collection and analysis are the core elements.
  3. AI Control:
    • This stage leverages artificial intelligence technologies to control the system.
    • Technologies like machine learning and deep learning are utilized.
  4. Virtual:
    • This stage involves the implementation of systems in a virtual environment.
    • Simulation and digital twin technologies are employed.
  5. Massive Data:
    • This stage emphasizes the importance of collecting, processing, and utilizing vast amounts of data.
    • Technologies like big data and cloud computing are utilized.

Throughout this progression, there is a gradual shift towards automation and increased intelligence. The development of data and AI technologies plays a critical role, while the use of virtual environments and massive data further accelerates this technological evolution.
