Hi all, Great work. However, I fundamentally do not believe in the approach of ‘letting reviewers pick the best features’. There is no way we would ever get something working out if it. We need to get _one_ working solution here, and figure out how to best get there. I would propose to do it bottom up, starting with the basic multi-simulator instance support, checkpointing support, and then move on to the network between the simulator instances.
Thus, I propose we go with the low-level plumbing and checkpoint support from what Curtis has posted. I believe proper checkpointing support to be the most challenging, and from what I can tell this is far more limited in what you just posted Mohammad. Could you perhaps review Curtis patches based on your insights, and we can try and get these patches in shape and committed asap. Once we have the baseline functionality in place, then we can start looking at the more elaborate network models. Does this sound reasonable?
