Abstract:
A method of transferring data from a first node to a second node in a multi-processor system comprising a plurality of nodes coupled to an interconnect fabric, the nodes comprising a plurality of compute nodes and a plurality of I/O nodes, each I/O node coupled to a plurality of data storage devices, the method comprising the steps of:generating a I/O request packet in a first node in response to an I/O request from an application executing in the first node, the I/O packet havinga data transfer request;an interconnect destination-side channel program;a first debit ID designating a second node buffer where the data request will be transmitted; anda first credit ID designating a first node buffer where the data responsive to the I/O request will be transmitted;transmitting the data request packet to a second node via the interconnect fabric; andexecuting the destination-side interconnect channel program to extract the first debit ID to transfer the data request to the second node buffer.
