After logging into the master module, each bus subscriber waits a predefined period of time to see whether a further bus subscriber logs into the master module, and closes the bus system if no further bus subscriber logs into the master module within the predefined period of time.

Abstract: A system, a method, and computer program product for performing buffering operations. A data update is received at a buffering location. The buffering location includes a first buffer portion and a second buffer portion. The data update includes an address tag. The buffering location is communicatively coupled to a memory location configured to receive the data update.

The target address of the data update is pre-fetched from the memory location upon determination that the target address does not match the address tag. The first and second buffer portions buffer the data update using the pre-fetched target address.

Abstract: A computer program product, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se. Moreover, the program instructions are readable and/or executable by a controller to cause the controller to perform a method which includes: receiving a same input/output request along more than one communication paths, and evaluating a workload associated with each of the communication paths. A communication path having a lowest workload associated therewith is selected. Moreover, information corresponding to the input/output request as well as a status are sent along the selected communication path. The status sent indicates that the selected communication path was chosen to satisfy the input/output request. A special status indicating that none of the remaining communication paths were chosen to satisfy the input/output request is also sent along each of the remaining communication paths.
