METHOD AND APPARATUS FOR DYNAMIC RESIZING OF CACHE PARTITIONS BASED ON THE EXECUTION PHASE OF TASKS

摘要

The present invention proposes a method and a system for dynamic cache partitioning for application tasks in a multiprocessor. An approach for dynamically resizing cache partitions based on the execution phase of the application tasks is provided. The execution phases of the application tasks are identified and updated in a tabular form. Cache partitions are resized during a particular instance of the execution of application tasks such that the necessary and sufficient amount of cache space is allocated to the application tasks at any given point of time. The cache partition size is determined according to the working set requirement of the tasks during its execution, which is monitored dynamically or statically. Cache partitions are resized according to the execution phase of the task dynamically such that unnecessary reservation of the entire cache is avoided and hence an effective utilization of the cache is achieved.
