Embodiment Construction

[0030] Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] The present invention provides a technical solution: a parallel boundary scan method based on a large-scale computer system. The parallel boundary scan method is: 1. The system management terminal performs system-level parallel boundary scan on the system main control management module, and The number of parallel connections on the main control management module creates a corresponding number of threads; 2. The running system main control management module performs out-of-band diagnostic tests on parallel computer nodes; the system main control management module is provided with a diagnostic test module and a serial port terminal module, The system management terminal is equipped with diagnostic test data registers, host command registers, host data regis...

Abstract

The invention relates to the technical field of boundary scanning of computer systems, and discloses a parallel boundary scanning method based on a large-scale computer system, which comprises the following steps: 1, system-level parallel boundary scanning is performed on a system main control management module by a system management terminal, a corresponding number of threads are created according to the number of parallel connections on the system main control management module; 2, the running system master control management module performs out-of-band diagnosis test on parallel computer nodes. The diagnosis test module and the serial port terminal module are arranged in the system main control management module, so that the system main control management module can dynamically debug and manage the node controller under the condition of not influencing the normal operation of the system node, and can access the memory storage unit, the internal register and the external equipment, dynamic implicit faults and partial explicit static faults occurring in system operation can be detected.

Description

technical field [0001] The invention relates to the technical field of boundary scan of computer systems, in particular to a parallel boundary scan method based on a large-scale computer system. Background technique [0002] In modern electronic application systems, parallel computer systems are usually composed of multiple nodes, each node has its own microprocessor, node controller, local memory, interconnection communication interface, input and output devices, etc., forming a relatively independent system , all nodes are interconnected through the interconnection communication interface to form a high-performance parallel computer system. With the development of VLSI technology and the improvement of printed circuit board manufacturing technology, the performance of the current parallel computer system is improving day by day. The scale and complexity are also increasing day by day. It is necessary to use boundary scan technology to test whether the connection between th...
