SOFTWARE EMULATION METHOD OF CROSS BAR NETWORK ROUTER OF HIGH SPEED PARALLEL COMPUTER

摘要

The present invention relates to a software emulation method for a receiver of a crossbar network router in a high speed parallel computer, and solves a problem in which a message receiving kernel for a conventional crossbar network (Xcent-Net) was available only in a system having a crossbar network router board. To this end, the present invention provides a first process of converting an Ethernet message received from Ethernet by a first thread into a crossbar network router board message and storing the message in an empty buffer and then notifying the reception of the message. After the message is notified to the kernel receiver by the second thread, the kernel receiver performs the second process of removing the messages in the buffer when the kernel receiver finishes receiving the message. Therefore, even in an Ethernet-connected system without a crossbar network router board, the crossbar network is connected to the kernel receiver. Receive messages about It is the one to use.
