[Mpi-forum] MPI debugging interface

[Jeff Squyres]

This message is directed to MPI tool authors and my fellow MPI  
implementors.

I realize that this post is a little off-topic for this list (it does  
not have to do with official MPI standards stuff), but it seemed a  
good way to reach many MPI tool authors and implementors at once.

Open MPI has worked together with Allinea to extend the original  
"TotalView MPI Debugger API" to include some new functionality:  
returning meaningful information about MPI handles that can be  
displayed in a user-friendly way.  For example, instead of just  
displaying the value of the MPI_Comm variable "foo", show that it  
represents that this process is rank 7 of 9 in that communicator, the  
communicator is named "MPI_COMM_WORLD", ...etc.  We would like to  
present this work to other MPI implementors and tool authors for wider  
use.

If you are interested in participating in the discussion, please  
contact me off-list.

Thanks, and we now return you to your regularly scheduled programming.
