Block data mover adapted to contain faults in a partitioned multiprocessor system |
摘要 |
A system and method are provided for moving information between cache coherent memory systems of a partitioned multiprocessor computer system while containing faults to a single partition. The multiprocessor computer system includes a plurality of processors, memory subsystems and input/output (I/O) subsystems that can be divided into a plurality of partitions. Each I/O subsystem includes at least one I/O bridge for interfacing between one or more I/O devices and the multiprocessor system. The I/O bridge has a data mover configured to retrieve information from a "source" partition and to store that information within its own "destination" partition. When activated, the data mover issues a request to the source partition for a non-coherent copy of the information. The home memory subsystem in the source partition preferably responds to the request by sending the data mover "valid", but non-coherent copy of the information, e.g., a "snapshot" of the information as of the time of the request. Upon receiving the information, the data mover may copy it into the memory subsystem of the destination partition.
