Cluster computing system hybrid communication method based on embedded processor memory interface

Abstract

The invention provides a cluster computing system hybrid communication method based on an embedded processor memory interface. A network controller integrated with an embedded processor is connected to a first network through a network transceiver. A parallel memory interface is connected to a second network through a hybrid network communication module. When a parallel interface state machine receives data from a memory bus which is connected with the parallel memory interface, the data are stored in a transmit queue. A data packet is received from the second network through a receiving control logic and the data packet is disassembled, then the data packet is selectively stored in a receive queue or a forward queue according to a destination address of the data packet, and the receive queue buffers data to be forwarded to the parallel memory interface. When the receive queue is non-null and the memory bus which is connected with the parallel memory interface is not occupied, the data are sent to the memory bus. The transmit queue and the forward queue are arbitrated by a send control logic, and the oldest data packet is selected based on an age strategy to be sent.

Description

technical field [0001] The invention relates to the technical field of computing, and more specifically, the invention relates to a hybrid communication method of a cluster computing system based on an embedded processor storage interface. Background technique [0002] With the continuous development of ARM (Advanced RISC Machines) architecture processor technology, academia and industry have considered and are currently developing new low-power cluster systems based on ARM embedded processors. For example, Sandia National Laboratory released a system called "Mini Supercomputer" on May 1, 2011. The system consists of 196 Gumstix Overo Tide computing nodes, and every seven Gumstix Overo Tide is integrated into a Stagecoach motherboard. , and then realize the interconnection of nodes through Ethernet. Ludwig-Maximilians-Universitat (LMU) University in Germany built a cluster system using AppleTV in April 2011. Each node of the system contains a 1GHz Cortex-A8 processor, Power...
