Patent ID: 7966454

Claim:
A method for issuing global shared memory (GSM) operations from an originating task on a first node coupled to a network fabric of a distributed network via a host fabric interface (HFI), said method comprising: composing a GSM command associated with the originating task within a cache line of a cache corresponding to the first node of a plurality of nodes on the distributed network; responsive to completion of the composition of the GSM command associated with the originating task within the cache line, automatically forwarding the cache line directly to the HFI for issuing of the GSM command to the network fabric to complete processing of GSM operations corresponding to the GSM command within the distributed network; and wherein the HFI responds to receipt of a forwarded cache line by automatically generating a GSM packet containing GSM operations and data corresponding to the GSM command and wherein the HFI issues the GSM packet to the network fabric via a HFI window allocated to the originating task.
