Abstract
A system includes a processor with a memory map specifying a user mode region with virtual address translation by a memory management unit and a kernel mode region with direct virtual address translation. The processor executes an application in the user mode region where virtual addresses are not unique. A probe receives trace information from the processor. A host system receives the trace information from the probe. The host system includes a data structure associating a process name, a process identification and a set of instruction counters. Each instruction counter is incremented upon the processing of a designated virtual address within the trace information. A profiling module processes information associated with the process name and set of instruction counters to identify a performance problem in the application.
