Exposing MPI Objects for Debugging
SESSION: Poster Reception
EVENT TYPE: Posters
TIME: 5:15PM - 7:00PM
AUTHOR(S):Laust Brock-Nannestad, John DelSignore, Jeffrey M. Squyres, Sven Karlsson, Kathryn Mohror
ROOM:New Orleans Theater Lobby
ABSTRACT:
Developers rely on debuggers to inspect application state. In applications that use MPI, the Message Passing Interface, the MPI runtime contains an important part of this state. The MPI Tools Working Group has proposed an interface for MPI Handle Introspection. It allows debuggers and MPI implementations to cooperate in extracting information from MPI objects. Information that can then be presented to the developer. MPI Handle Introspection provides a more general interface than previous work, such as Message
Queue Dumping.
We add support for introspection to the TotalView debugger and a development version of Open MPI. We explain the interactions between the debugger and MPI library and demonstrate how MPI Handle Introspection raises the abstraction level to simplify debugging of MPI related programming errors.
