Abstract
Embodiments of the present invention provide a computing system and method to profile a program for finding potential optimization in heap usage by reducing lag and drag in lifetimes of heap memory blocks. The process consists of three steps. First, an instrumentation engine analyzes a given program and inserts additional code at interesting locations to collect needed information. Second, when the instrumented program is executed on a set of test cases, runtime data is collected. Third, since this data is large for a complex and long running program, data is processed to present it to a user in useful ways so that a programmer improves the heap utilization in the program.
