Methods and apparatuses for core allocations

Abstract

Apparatuses, systems, and methods to monitor core performance and integrated circuit chip temperatures in order to alternatively partition cores and core resources are disclosed. Embodiments generally comprise integrated circuit processors in chips that contain multiple cores or processing elements. In many system and apparatus embodiments, a module monitors either the throughput or performance of one or more of the cores. In such embodiments, another module, a core allocation module, partitions or allocates cores in different arrangements of partitions to improve performance. Additionally, in some embodiments, a temperature monitoring module monitors one or more temperatures of the chip containing the cores, wherein the temperature measurements may affect the core allocations. In some embodiments, once an allocation for the cores is selected, the specifics of the cores to be placed in different partitions may be stored and later retrieved when triggered by events allowing for the reallocation of the cores.
