SYSTEM AND METHOD FOR CAPACITY PLANNING FOR SYSTEMS WITH MULTITHREADED MULTICORE MULTIPROCESSOR RESOURCES

摘要

A method for expressing a hierarchy of scalabilities in complex systems, including a discrete event simulation and an analytic model, for analysis and prediction of the performance of multi-chip, multi-core, multi-threaded computer processors is provided. Further provided is a capacity planning tool for migrating data center systems from a source configuration which may include source systems with multithreaded, multicore, multichip central processing units to a destination configuration which may include destination systems with multithreaded, multicore and multichip central processing units, wherein the destination systems may be different than the source systems. Apparatus and methods are taught for the assembling of and utilization of linear and exponential scalability factors in the capacity planning tool when a plurality of active processor threads populate processors with multiple chips, multiple cores per chip and multiple threads per core.

1. A method of determining a set of scalability factors for linear and exponential scaling characteristics of an operating system, the method comprising:
receiving a set of CPU performance data; storing the set of CPU performance data in an internal CPU performance repository; deriving an analysis of the set of CPU performance data by a set of characteristics of the operating system, a chip architecture set, a number of chips, a number of cores per chip, and a number of supported threads per core; and determining the set of scalability factors based on the analysis.
