Abstract:
1. 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: generating a GSM command within an effective address (EA) space of the originating task, wherein the originating task executes on the first node of a plurality of nodes across the distributed network, which plurality of nodes collective perform a global job that includes the originating task; placing the GSM command within a send FIFO allocated to the originating task, wherein the send FIFO is a portion of real memory having real addresses (RA) that are mapped, within the first node, to EAs of a globally executing job for which the originating task maintains only a portion of the real address space mapped to the EAs of the globally executing job; enabling retrieval of the GSM command from the send FIFO to a HFI window allocated to the originating task, wherein the HFI window utilizes information from the GSM command to generate a GSM packet that contains at least one of GSM operations and data; and issuing the GSM packet to the network fabric via the HFI window.
