Non-uniform memory access (NUMA) computer system includes at least two nodes interconnected by node, wherein the at least one node comprising a processor for interrupt service. 把这些节点分割成多个外部中断域,从而总是把外部中断提交给其中出现该中断的外部中断域内的处理器. These nodes are divided ...

The first computer to provide interrupts was probably the UNIVAC 1103A (1956). The book "Computer Architecture" by Blaauw and Brooks discusses different approaches to interrupts in great detail, pages 418-434. A history of interrupts is inthis article.↩ ...
The next step in architecture development was namedx2APIC. The number of possible CPUs in the system was increased to 2^32. These controllers can work in a backwards compatibility mode with xAPIC, or they can work in the new x2APIC mode. In this new mode controller programming is not do...
In subject area: Computer Science An Interrupt Request (IRQ) is a signal from a device or program that prompts a Real-Time Operating System (RTOS) to pause its current task and determine the next action to take. It helps prioritize tasks and manage multiple interruptions in a computer system...
In general, an I/O interrupt handler must be flexible enough to service several devices at the same time. In the PCI bus architecture, for instance, several devices may share the same IRQ line. This means that the interrupt vector alone does not tell the whole story. In the example shown...

Storage device controllers generally interface with one or more host devices via one of various host computer interface protocols such as, for example, Serial Advanced Technology Attachment (SATA), in accordance with the Serial ATA 2.6 Specification (February 2007), hereinafter, “SATA protocol”, av...
