Introduction Summary Lessons will be broken down into three modules: GMS (i.e. can we use peer memory for paging across LAN) and DSM (i.e. can we make the cluster appear as a shared memory machine) and DFS (i.e. can we use cluster memory for cooperative caching of files) Context for Global Memory Systems Summary Key…
