A method, system and memory controller for implementing dynamic enabling and disabling of cache based upon workload in a computer system. Predefined sets of information are monitored while the cache is enabled to identify a change in workload, and selectively disabling the cache responsive to a first identified predefined workload. Monitoring predefined information to identify a second predefined workload while the cache is disabled, and selectively enabling the cache responsive to said identified second predefined workload.

Implementing dynamic cache enabling and disabling based upon workload

An apparatus includes a processor and a volatile memory that is configured to be accessible in an active memory sharing configuration. The apparatus includes a machine-readable encoded with instructions executable by the processor. The instructions including first virtual machine instructions configured to access the volatile memory with a first virtual machine. The instructions including second virtual machine instructions configured to access the volatile memory with a second virtual machine. The instructions including virtual machine monitor instructions configured to page data out from a shared memory to a reserved memory section in the volatile memory responsive to the first virtual machine or the second virtual machine paging the data out from the shared memory or paging the data in to the shared memory. The shared memory is shared across the first virtual machine and the second virtual machine. The volatile memory includes the shared memory.
