REDUCING CACHE TRANSFER OVERHEAD IN A SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18154204 titled 'REDUCING CACHE TRANSFER OVERHEAD IN A SYSTEM

Simplified Explanation

The patent application describes a method and system for detecting and handling hot cache lines in a processor.

  • The method and system detect a cache line as a potential or confirmed hot cache line when the processor receives an intervention related to fetching the cache line.
  • The system suppresses the actions of operations associated with the hot cache line to optimize performance.
  • Another method and system detect an intervention and notify another processor about it.
  • An alternative method and system identify a hot data object associated with an intervention event of an application.
  • The method and system can suppress actions of operations associated with the hot data object to improve efficiency.
  • Another method and system can detect and communicate an intervention related to a data object.

Potential Applications

  • This technology can be applied in processors and computer systems to improve cache performance.
  • It can be used in high-performance computing environments where efficient cache utilization is crucial.
  • The method and system can be implemented in servers, data centers, and cloud computing platforms to enhance overall system performance.

Problems Solved

  • Hot cache lines can significantly impact the performance of processors and computer systems.
  • By detecting and handling hot cache lines, this technology helps to optimize cache utilization and improve overall system efficiency.
  • The method and system also address the issue of interventions and provide mechanisms to handle them effectively.

Benefits

  • Improved cache performance and utilization.
  • Enhanced overall system efficiency and responsiveness.
  • Reduction in the impact of hot cache lines on processor performance.
  • Efficient handling of interventions and communication between processors.


Original Abstract Submitted

A method and a system detects a cache line as a potential or confirmed hot cache line based on receiving an intervention of a processor associated with a fetch of the cache line. The method and system include suppressing an action of operations associated with the hot cache line. A related method and system detect an intervention and, in response, communicates an intervention notification to another processor. An alternative method and system detect a hot data object associated with an intervention event of an application. The method and system can suppress actions of operations associated with the hot data object. An alternative method and system can detect and communicate an intervention associated with a data object.
