Abstract

A dynamic shared cache partitioning scheme for multi-core processors is presented. Capacity misses produced by the running processes are continuously evaluated and used to assign the available space in a shared cache memory. The administration of the resources gets a reduction of up a 20% in the global miss rate of all the executed processes when compared to a Capitalist management policy. Also IPC and bandwidth were evaluated. The dynamic management proposed fulfills its objective of managing the shared cache space for every process while improving the performance.
