摘要： Lock granularization opportunities are identified in computer code. A processor is used to generate synchronized code blocks and fields (data) accessed in each code block. Each of the code blocks can then be represented by a set. A list of non-intersecting synchronized code blocks having no commonly accessed fields is generated, and a list of intersecting synchronized code blocks (code blocks each having at least one commonly accessed field) is also generated. Equal and superset-subset lists are then generated from the list of intersecting synchronized code blocks. Granularized locks are applied directly around the fields that are accessed within code blocks represented by non-intersecting and equal sets. Granularized locks are also applied around the fields that are accessed within code blocks represented by the superset, and the same locks are applied to code blocks represented by the subsets, thereof.
