Apparatus and method for enforcing homogeneity within partitions of heterogeneous computer systems

摘要

A heterogeneous computer system has multiple interconnected cells, each cell has multiple primary processors of the same Instruction Set Architecture (ISA) type, but different cells may have processors of different ISA types. Each cell has a cell type register readable by a processor external to the cell. The cell type register of each cell is used at system startup time to ensure that all processors of a system partition have compatible ISA types.
