Abstract
A DSM system includes a local node, a first remote node, and a second remote nodes. The data access method for a remote node to access a local node in the DSM system includes the steps of directly receiving data of a local memory line from a local memory of the local node, and transmitting the data to the first remote node when the local memory line is in HOME-N or SHARED status; directly receiving data of the local memory line from the second remote node, and transmitting the data to the first remote node when the local memory line is in a GONE status; and asserting a transaction to a system bus to read data of the local memory line, receiving the data via the system bus, and transmitting the data to the first remote node when the local memory line is in HOME-M status.
