Abstract:
1. A process for visually representing in a stack prefix view at least a portion of call stack data of multiple call stacks in a parallel programming system, the process comprising the steps of: constructing in a memory, through execution by at least one processor of instructions which search a set of nodes for nodes that represent similar stack frames, a stack prefix graph based on call stack data of multiple call stacks, the call stack data comprising stack frames having an order based on calling sequence, each stack frame located at a respective depth within a call stack, the stack prefix graph having nodes which represent stack segments and arcs which represent adjacency of stack segments, at least one of the stack segments including a plurality of stack frames which are similar to one another, two stack frames being deemed similar when each of the stack frames represents execution of code in the same method body, as opposed to different stack frames representing execution in different respective method bodies; and displaying on a screen a visual representation of the stack prefix graph.
