All questions are based on Huang's paper, with the clarifications made in class: the controller does not have a state active or idle. during initialization, the controller sends one or more basic msgs, using the same code as in R1. after initialization, the controller never sends any basic msgs. Ignore the controller part in R1. Assume perfect arithmetic: no rounding errors, underflow, overflow Modified version of R3: An active proc i, on becoming idle, sends a C(w1) to a process j corresponding to each basic(w1) msg that i has received from j since the last time that i was idle
