Abstract: The invention relates to a system and method for demarcating information related to one or more blocks in an application source code. This invention provides a means to annotate block information in the source code. It parses the application source code to generate an abstract syntax tree and instruments the source code to capture information related to the one or more blocks generated at the time of dynamic analysis of the application. The information related to the one or more blocks are stored in Hash Map and based on this information the abstract syntax tree is modified to add the information related to the one or more blocks and inserting this information in the application source code.

Abstract: This invention relates to a method, computer readable medium, and apparatus for identifying one or more problematic loops in an application. This invention provides a Directed Acyclic Graph or DAG representation of structure of one or more loops in the application by performing a static and a dynamic analysis of the application source code and depicts the loop information as LoopID, loop weight, total loop iteration, average loop iteration, total loop iteration time, average loop iteration time and embedded vector size. This aids a programmer to concentrate on problematic loops in the application and analyze them further for potential parallelism.
