ABSTRACT:
Embodiments of the present invention provide methods and apparatuses for accessing MD atomically. For one embodiment, the local cache and the remote cache are each provided with an MBE. To perform an atomic access operation, the local processing system allocates a burst descriptor buffer. The burst descriptor buffer is used to specify the addresses to be atomically accessed. For write operations, the burst descriptor buffer also specifies the update data. The addresses, and data, if any, are then transmitted to the remote cache as a series of packets constituting a single data access request. The MBE of the remote cache then performs the operations contained in the request. Upon completion of all of the operations the remote MBE transmits an acknowledgement. For read operations the remote MBE also transmits the requested data.
