Methods and apparatus to manage workload memory allocation

摘要

Methods, articles of manufacture, and apparatus are disclosed to manage workload memory allocation. An example method includes identifying a primary memory and a secondary memory associated with a platform, the secondary memory having first performance metrics different from second performance metrics of the primary memory, identifying access metrics associated with a plurality of data elements invoked by a workload during execution on the platform, prioritizing a list of the plurality of data elements based on the access metrics associated with corresponding ones of the plurality of data elements, and reallocating a first one of the plurality of data elements from the primary memory to the secondary memory based on the priority of the first one of the plurality of memory elements.

1. At least one computer readable hardware medium comprising instructions that, when executed, cause a machine to, at least:
monitor access of first and second data records during a workload runtime to generate a log; analyze the log to assign the first and second data records to a respective first subset and a second subset based on a frequency of access, the first record in the first subset being accessed at a higher frequency than the second record in the second subset during a first portion of the workload; during the first portion of the workload, assign the first subset to a main memory, and assign the second subset to a secondary storage device; when the frequency of access of the first subset is lower than the frequency of access of the second subset during a second portion of the workload, relinquishing the first subset from the main memory and assigning the second subset to the main memory.
