Abstract
The present invention provides a probe system and method for multithreaded user-space programs. The system includes an instrumentation module that enables single stepping out of line processing for multithreaded programs, an establish probepoint module that divides up an area of the probed program's memory into a plurality of instruction slots, an ensure slot assigned module that ensures that an instruction slot is assigned to a probepoint, a slot acquisition module that acquires the instruction slot for the probepoint, stealing a slot from another probepoint as needed, and a free slot module that relinquishes the instruction slot owned by the probepoint when the probepoint is being unregistered.
