ABSTRACT:
A method of analyzing performance of a program executing in a computer system. A user provides a set of user defined region of the program. Thus, a user has the flexibility to choose the regions of program code profiled. The performance of user defined regions of the program is measured by a set of run-time metrics. Each user defined region is associated with a range break point. Run-time metrics measuring the performance of user defined regions of the program are updated, during execution, whenever a range break point is set. The handling of range break points may be implemented, for example, by specialized hardware and software. This method may be less intrusive than instrumentation based profiling but more accurate than sampling based profiling.
