Glоbаl Memоry Systems The cоntext for this question is the sаme аs the previous question. Based on the Global Memory Systems (GMS) architecture, analyze the following multi-node scenario. Use the provided terminology for your answers. For any given page: PFD States: Local-Private — node owns an exclusive local copy, Local-Shared — multiple nodes hold shared copy, Global-Private - node holds the page in its global memory on behalf of another node, Non-existent — node does not hold any copy. GCD: Home Node for a given page; given a UID it returns the node IDs that are currently hosting the page in set notation, e.g., {X, Y} Initial Scenario (Time T0) A 3-node cluster consists of Node A, Node B, and Node C. For the data page P, Node A is the Home Node. At T0, Node A has just loaded Page from disk into its local part of the DRAM for a process. Nodes B and C are currently idle. Current Status at T0 with respect to page P: GCD at Home Node for P: {A} PFD at Node A: Local-Private PFD at Node B: non-existent PFD at Node C: non-existent c) [2 points] Event 2 (Time T2>T1) Node A experiences memory pressure and intends to evict Page P. The page is clean (i.e., not dirty). Node C would be the candidate node to send the page. Should Node A decide to keep the page in the cluster. Provide the status for the following 4 entries after Event 2: [0.5 points] GCD Owner List at Home Node: (List) ________ [0.5 points] PFD at Node A: (State) __________ [0.5 points] PFD at Node B: (State) __________ [0.5 points] PFD at Node C: (State) __________
