Abstract: In a computer system having a configuration which is subject to change, because of failure replacement, updating, or expansion, it is necessary to provide means for loading parameters carrying the present system configuration into the active modules of the system. In this manner, all parallel processors are identified and recognized and depending upon system demands, used because of the parameter loading arrangement of this computer system. Serial lines are provided for loading the parameters into the active modules.

Abstract: A computer system operative during an initialization phase to initialize modules of the system and during a subsequent non-initialization phase to transfer information between the initialized modules. A module bus (MB) has 32 signal lines beginning with a least-significant-bit signal line and ending with a most-significant-bit signal line. The bus (MB) connects the modules for data transfers after the initialization phase over bidirectional address lines and data lines connected to the module bus. A system support module (SSMI) starts the initialization phase by energizing an initialization signal line (INIT). In response, a processor (GDP) generates identification command information over the bus (MB) that continas a first data record and a second data record.
