Problems solved by technology

But on the other hand, it also means that regular blade systems don't have the performance of a symmetric multiprocessor in a blade because of the lack of synchronization or timing edge correction

Embodiment Construction

[0014] The present invention provides a standby timing structure, so that the blade cluster system device has the characteristics of high-order symmetric multiprocessor, so that it has a flexible system structure.

[0015] see image 3 , a blade cluster system mainly includes a central sequencer 10 and several blade modules 20 , 30 , 40 , 50 . The blade cluster system basically includes necessary hardware devices and a cluster management system (not shown in the figure) to manage the operation of the blade modules 20 , 30 , 40 , 50 . (In order to provide a clearer description, other system components included in the blade cluster system are omitted in the drawings.) The cluster management system is a software program that acts as an interface between blade modules 20, 30, 40, 50 and users Management / Operational Interface. In the present invention, the cluster management system supports cluster computing, including asymmetric clustering and symmetric clustering with / without a...

Abstract

The present invention discloses a spare timing distribution structure, which enables the blade cluster system to have the performance of symmetrical multiprocessors and can flexibly configure the system; this structure mainly provides a central timing signal by a central timing device, and is configured in the system The regional timing signals that can be operated on each blade module provide regional timing signals; the timing multiplexer selects the central timing signal and sends it to several regional timing users located in each blade module; if the central timing device fails, the timing multiplexer switches to change To send regional timing signals.

Description

technical field [0001] The invention relates to a timing distribution structure in a computer system, in particular to a backup timing distribution structure in a blade cluster system with symmetric multiprocessor performance. Background technique [0002] For now, the essential difference between a symmetric multiprocessor system (SMP system) and a blade clustering system (bladeclustering system) is still difficult to break. Both systems are designed for certain purposes and to function in certain configurations. To combine the two types of systems into one, timing allocation will be one of the main issues. [0003] In general, reliable and high-end symmetric multiprocessor systems have a backup timing distribution system, while typical blade systems have dedicated local timing generation and distribution systems on each blade. [0004] figure 1 An example of a high-order symmetric multiprocessor system with timing distribution in the conventional art. A system with sev...
