Abstract
Techniques to prioritize and optimize the execution of upgrade operations are described. A technique may include determining the size of data blocks that are to be copied from one storage medium to another, and the dependencies of upgrade tasks on the data blocks and on other tasks. A task may be prioritized according to a weight that includes the cumulative sizes of the data blocks that it and its dependent tasks depend on. A data block copying may be prioritized according to the cumulative weights of the tasks that depend on that data block. Some embodiments may perform several data copying and/or tasks in parallel, rather than sequentially. Other embodiments are described and claimed.
