Breezy

Breezy is an implementation of an architecture that allows a client application to "attach" to a data parallel (pC++) program at run-time. This "attachment" allows the client to

• control execution,
• retrieve:
  • parallel data,
  • information about the program state (including current location in the program, currently active parallel data structures, etc.),
  • type information regarding parallel data structures, and
  • meta information (I could tell you what this is, but I'd have to kill you).
• call user defined functions or methods in the parallel program

Here are some documents regarding the ideas and details of Breezy.

• Language Based Parallel Program Interaction: The Breezy Approach. This paper was accepted to the IHPCC (Internation High Performance Computing Conference) in New Delhi.
• The Breakpoint Executive (the parallel program side of Breezy).
• The Breezy API (the client application side of Breezy).

Here are some example applications of Breezy.

• A simple debugger built on Breezy, part of the TAU environment.
• Visualization of a pC++ program.
• The DAVE project.

Soon (maybe) to come:

• The socket communication library (cargo.c & transport.c).
