2.2 The Interconnection Network

The data network and the control network of the CM-5 provide for interprocessor communication. All the processing nodes and the control processors of a CM-5 connect to these two networks. While the control network is used for global operations such as synchronization and broadcasting, the data network is used for communication between individual processors. The data network is capable of delivering messages to nearby nodes at rates upto 20MBps.
