Methods and apparatus to manage workload memory allocation

A system to migrate data to memory, the system comprising:

• first memory having a first latency;
• second memory having a second latency, the second latency lower than the first latency associated with the first memory;
• means for identifying access instances to identify hot data based on first memory access instances occurring during a first time period of a workload, the access characteristics instance identifying means to identify cold data based on second memory access instances occurring during the first time period of the workload;
• means for sorting the hot data to be migrated;
• and
• means for managing memory to, during the first time period of the workload:
• migrate the cold data to the first memory;
• and
• migrate the sorted hot data to the second memory, the memory managing means to, during a second time period of the workload:
• migrate at least some of the cold data to the second memory;
• and
• migrate at least some of the sorted hot data to the first memory.

A tangible computer readable medium comprising computer readable instructions that, when executed, cause at least one processor to at least:

• identify hot data based on first memory access instances occurring during a first time period of a workload;
• identify cold data based on second memory access instances occurring during the first time period of the workload;
• sort the hot data to be migrated;
• migrate, during the first time period of the workload, the cold data to a first memory, the first memory having a first latency;
• migrate, during the first time period of the workload, the sorted hot data to a second memory, the second memory having a second latency lower than the first latency associated with the first memory;
• migrate, during a second time period of the workload, at least a portion of the cold data to the second memory;
• and
• migrate, during the second time period of the workload, at least a portion of the sorted hot data to the first memory.
