A method includes: by an application executed by a first node, determining whether a non-transparent bridge between the first node and a second node is in a disconnected state; sending a re-initialization request from the application to a driver executed by the first node when the NTB is in the disconnected state; re-initializing a memory of the first node upon the driver receiving the re-initialization request; transmitting a result message related to the re-initialization of the memory to the second node; and implementing a memory-sharing procedure upon completing the re-initialization of the memory and receiving, from the second node, another result message related to re-initialization of a memory of the second node.
