Working Groups
Certain threads interract together more than others. This is often shown by a cpu swapping said threads at a high rate. To show the threads in a more efficient way, they should be grouped together by clique. A group of polytechnique students is already working on this issue. They are attacking the problem with 2 steps: 1- flatten the list, as trees make little sense when shuffling the threads. 2- apply an algorithm to show thread affinities (to each other, not to a cpu) The first step's first iteration is here. https://git.eclipse.org/r/#/c/68231/ The reason I would suggest that the action be a button is that it is toggled, and if someone applies an optimization, the list is converted to a flat list, so there is visual feedback.
