Method, device and system for determining cache memory unit conflict level
By calculating the dispersion index of the number of access requests to cache storage units, the problem of the inability to effectively assess the conflict level of cache storage units in the existing technology is solved. This provides a quantitative basis for accurate assessment and optimization of the conflict level, and improves the utilization and bandwidth of the cache.

AI Technical Summary
Technical Problem
Existing technologies cannot effectively assess the conflict level of cache storage units, leading to a decrease in cache utilization and bandwidth.
Method used
By obtaining access request data from multiple cached storage units, the dispersion index of the number of access requests for each storage unit is calculated, including the coefficient of variation, range, interquartile range, and standard deviation, to determine the level of conflict in the cached storage units.
Benefits of technology
It accurately reflects the severity of conflicts, provides quantitative basis for optimization, is compatible with different caching architectures, reduces false positive and false negative rates, and improves the practicality and reliability of detection.

Abstract
The present application relates to the technical field of computer, and specifically discloses a method, device and system for determining cache memory unit conflict level, wherein the method is executed by a processor; the method comprises: obtaining access request data of each memory unit in a plurality of memory units of a cache; in the case that the total number of access requests received by the plurality of memory units of the cache is greater than or equal to a preset load threshold, calculating a discrete degree index of the number of access requests of the plurality of memory units according to the number of access requests of each memory unit in the plurality of memory units, and obtaining the cache memory unit conflict level. The above scheme can effectively evaluate the cache memory unit conflict level.
