%X In this paper we introduce a tool for debugging parallel
   programs which utilize the popular MPI (message passing
   interface) C library. The tool is called The Distributed
   Application Debugger and introduces distinct components
   around the code being debugged in order to play, record, and
   replay sessions of the user\[rs]s code remotely. The
   GUI component incorporates the popular GDB debugger for
   stepping through code line by line as it runs on the
   distributed cluster as well as an analysis tool for stepping
   through the executed portions of code after the session has
   completed. While the system is composed of
   multiple components, the logistics of coordinating them is
   managed without user interaction; requiring the user to only
   provide the location of the program to debug before
   starting.
