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 parallel update method and a system for large-scale computer node guiding procedure. The update customer terminal transmits update order and data to every node of the large-scale computer in parallel by a communication support module. The node update service module at every node receives the update order and data of the update customer terminal to update the guiding procedure of every node. The update system comprises a communication support module, an update customer terminal running at the ordinary micro-computer and a node guiding procedure update module arranged at every node of the large-scale computer. All the node update service modules are connected with the update customer terminal by the communication support module to answer for the update order of the customer terminal and finally realize the parallel update of every node guiding procedure. The invention adopts the parallel mode and has the advantages of simple structure, convenient operation and capability of resolving the problem of time and energy consuming of the guiding procedure in the large-scale system.

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 ...
