Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] The invention provides a method for parallel updating bootstrap programs of large-scale computer nodes. The update client sends update commands and data in parallel to each node of the large-scale computer through a communication support module, and the node update service module on each node receives the update client's Update the bootloader of each node after updating the command and data. In a preferred embodiment, the update client determines the number of sub-threads to create according to the number of nodes in the node list. Each sub-thread corresponds to a node. After all sub-threads receive the update node, they start the update operation. The node performs the handshake operation. After the success, it starts to send the update command and guide the program to update the data, and waits for the update result. After al...

Abstract

The invention discloses a large-scale computer node boot program parallel update method and system. The update client sends update commands and data in parallel to each node of the large-scale computer through a communication support module, and the node update service module on each node receives the update Update the bootloader of each node after the update command and data of the client. The update system includes a communication support module, an update client running on an ordinary microcomputer, and a node bootloader update module arranged on each node of a large-scale computer, and all node update service modules are connected to the update client through the communication support module, Respond to the update command of the client and finally realize the parallel update of the bootstrap of each node. The invention adopts a concurrent mode, has simple structure and convenient operation, and can effectively solve the problems of time-consuming and labor-intensive updating of boot programs in large-scale systems.

Description

technical field [0001] The invention mainly relates to the field of large-scale computers, in particular to a method and system for parallel updating of boot programs of large-scale computer nodes. Background technique [0002] The computer system bootloader is a program that is loaded and run when it is powered on or reset, and is usually solidified in a non-volatile memory. The boot program initializes the hardware and guides other programs such as the operating system boot program. It collects the most basic information of the hardware devices in the system and provides the system with the lowest and most direct hardware control. In the process of system development, with the continuous upgrade of the boot program, the continuous increase of functions or the correction of errors, the boot program needs to be updated frequently. There are many ways to update a single bootloader, which can be mainly divided into two categories: 1) offline update, the storage medium of the ...
