Abstract: Dynamic optimization is one of the most important essential techniques for computing system virtualization. Similar to virtualization technologies， the coming of multi-core era brings new chances for the development of dynamic optimization techniques. Based on the analysis of some existing dynamic optimization systems， such as Dynamo， Pin and Jrpm，the problems and challenges of traditional dynamic optimization mechanisms on multi-core platform are concluded. Moreover， a possible dynamic optimization framework on multi-core platform and the key issues to implement it are also discussed.
