$ echo hostname port | sudo tee /sys/fs/dmap/start_server #start server on each node in cluster

$ echo hostname port | sudo tee /sys/fs/dmap/add_neighbor #add node into cluster

$ cat /sys/fs/dmap/id #query node UID

$ cat /sys/fs/dmap/neighbors #query nodes in cluster

Usage:

$ ./dmap-client hostname:port set key value #add key-value

$ ./dmap-client hostname:port get key #query value by key

$ ./dmap-client hostname:port upd key value #update key value

$ ./dmap-client hostname:port cmpxchg key exchange comparand #compare exchange key value

$ ./dmap-client hostname:port del key #delete key
