PTT helps users to analyze and understand correction and performance
problems for multi-threaded applications. It shows when a program calls
NPTL routines and when it exits from them, with details about the
internal mechanisms of the library. It is a post mortem analysis; the
trace can be analyzed once the application has stopped. Three different
trace formats are provided: a machine readable text format, a human
readable text format, and a graphical format. The graphical format is
obtained thanks to Pajé, an interactive visualization tool.
