PARALLEL INFORMATION SYSTEM UTILIZING FLOW CONTROL AND VIRTUAL CHANNELS

摘要

Embodiments of a data handling apparatus can include a network interface controller configured to interface a processing node to a network. The network interface controller can include a network interface, a register interface, a processing node interface, and logic. The network interface can include lines coupled to the network for communicating data on the network. The register interface can include lines coupled to multiple registers. The processing node interface can include at least one line coupled to the processing node for communicating data with a local processor local to the processing node wherein the local processor can read data to and write data from the registers. The logic can receive packets including a header and a payload from the network and can insert the packets into the registers as indicated by the header.

1. A data handling apparatus comprising:
a network interface controller configured to interface a processing node to a network, the network interface controller comprising:
a network interface comprising a plurality of lines coupled to the network for communicating data on the network;a register interface comprising a plurality of lines coupled to a plurality of registers;a processing node interface comprising at least one line coupled to the processing node for communicating data with a local processor local to the processing node, the local processor being configured to read data to and write data from the plurality of registers; anda packet-former configured form packets comprising a header and a payload, the packet-former configured to use data from the plurality of registers to form the header and to use data from the local processor to form the payload, and configured to insert formed packets onto the network.
