1. A method comprising: receiving, in an application programming interface (API) of instrumented code corresponding to a version of code, an identification of an implicitly created task of the instrumented code, the instrumented code to be executed in a multi-core processor; associating said implicitly created task with at least one actual coded task of the instrumented code and using a duration of the at least one actual coded task to indicate a duration for the implicitly created task wherein the implicitly created task was implied from the at least one actual coded task; and providing, via a display of a system, a visualization of a relationship between the actual coded and implicitly created tasks and including a graphical representation of the duration of the implicitly created task based on a minimum and a maximum of the at least one actual coded task; wherein an implicitly created task is one that is logically derived from an actual coded task and a transitive relationship, without user intervention.
