1. A method for optimizing a data packet in a high performance computer system, comprising the steps of:

  • preparing a payload of the data packet;

    passing the prepared payload to a communications endpoint processor (CEP) kernel;

    appending, by the CEP kernel, a header to the prepared payload to generate a CEP kernel protocol unit that is optimized for a processor environment;

    transmitting, by the CEP kernel, the CEP kernel protocol unit to a CEP driver that is optimized for high throughput and low latency, and transforming, by the CEP driver, the transmitted CEP kernel protocol unit into one of a plurality of CEP kernel protocol unit formats depending upon a size range of the payload, each of the plurality having a different format for efficient handling by a CEP engine that is configured to automate communication tasks and to interface to a system memory controller for direct memory operations.
