==Multiprocessor System and Method for Configuring Multiprocessor System - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18151705 titled 'Multiprocessor System and Method for Configuring Multiprocessor System

==Simplified Explanation==

==Abstract==
A multiprocessor system is described that includes a processor in a local domain and a PCIe device in an external domain. The system ensures that when the processor in the local domain cannot find the PCIe device in the external domain, an access conflict is avoided by interconnecting the PCIe switches in the two domains. This allows the processor or a PCIe device in the local domain to access the PCIe device in the external domain without any issues. The communication path for this cross-domain access is established using a bus and the PCIe switches, eliminating the need for processor forwarding.

==Bullet Points==
* Multiprocessor system with a local domain processor and an external domain PCIe device.
* Avoids access conflicts when the local domain processor cannot find the external domain PCIe device.
* Interconnects PCIe switches in the two domains to enable normal access.
* Communication path for cross-domain access established using a bus and PCIe switches.
* Eliminates the need for processor forwarding.

==Potential Applications==
* Data centers and server systems with multiple processors and PCIe devices.
* High-performance computing clusters.
* Cloud computing infrastructure.
* Network routers and switches.

==Problems Solved==
* Avoids access conflicts when a processor in a local domain cannot find a PCIe device in an external domain.
* Ensures normal access to the PCIe device without any issues.
* Establishes a communication path for cross-domain access without relying on processor forwarding.

==Benefits==
* Improved system reliability and performance.
* Simplified communication path setup for cross-domain access.
* Enhanced scalability for multiprocessor systems.
* Enables efficient utilization of PCIe devices in external domains.


==Original Abstract Submitted==

A multiprocessor system includes a processor in a local domain that performs enumeration, and when a PCIe device in an external domain is not found by the processor in the local domain, an access conflict is avoided when PCIe switches in the two domains are interconnected, and the processor or a PCIe device in the local domain normally accesses the PCIe device in the external domain. Further, a communication path of the cross-domain access is established by using a bus and the PCIe switches in the two domains, and does not depend on forwarding of a processor.
