Method and system to identify serial code regions

摘要

A method and system to identify serial code regions in applications is described. The method includes instrumenting an application's code at loop entry points and loop exit points and gathering data about a plurality of loops in the application. The data may include the amount of time spent in each loop, the number of times each loop is executed, and/or loop hierarchies. A list of the loops may be displayed based on the gathered data. One or more of the plurality of loops may be selected for threading based on the gathered data. Directives may then be inserted into the application's code to thread one or more of the plurality of loops. The threaded loops may then be simulated and any resulting errors may be displayed.
