Abstract

Apparatus for efficiently interconnecting OEMI channels of a multiprocessor facility. A plurality of channel adapters are connected to individual channels from a plurality of processors. A supervisory interrupt driven microprocessor receives a link request from a channel adapter when the channel adapter has determined that two logical adapters are in an appropriate architected state. The microprocessor will assign a data bus to channel adapters involved in a link request if certain criteria is met by said link requests, signifying an efficient transfer between said channel adapters is likely.
