TI's uses cases all focus on 10 to 50 contexts in the debug view. They currently feel that dealing with more than 100 contexts requires a new approach. TI's approach is to use the Debug View with a recursive set of containers, where the backend debugger remains the top-level entity.

From a user-perspective, we want to be able to actively focus on a small amount of contexts, while making the others available in case they become of interest.

Filtering of information is essential to this effort. Grouping and hiding are trying to address this.

Clean up wiki page to help people add their use-cases of interest, to help keep focus on the problems we face. [Marc]

Discussions on Tilera's Grid view:

• • The view has proven useful, but mostly when knowledge about the underlying hardware was relevant to the problem being debugged.
  • Software designers still saw their software as a generic grouping of processes and threads, as shown in the Debug View.
