MULTISYSTEM SHARED MEMORY - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18215535 Titled 'MULTISYSTEM SHARED MEMORY'
Simplified Explanation
This abstract describes a system that consists of multiple devices connected to each other through an optical communication link. These devices share a common memory. In this system, some devices act as producers by sending broadcast messages, while others act as consumers by receiving messages from other devices.
When a producer device sends a packet, it holds a lock on a specific portion of the shared memory called a cache line. In response to this packet, the receiving devices send an acknowledgement or negative acknowledgement. They also invalidate the cache line in their local copy of the shared memory, meaning that the data in that cache line is no longer considered valid.
As the devices process data received over the optical communication link, they can update the cache line in their local copy of the shared memory. This allows for efficient sharing and processing of data among the devices in the system.
Original Abstract Submitted
A system includes multiple devices with a shared memory. The devices interconnect to each other via an optical communication link, with broadcast sends as producers, and receiving messages from others as consumers of the other devices. The devices receive a packet from a producer that has a lock on a cache line of the shared memory. In response to the packet, the devices send an acknowledgement or negative acknowledgement, and invalidate the cache line that is the subject of the message in a local copy of the shared memory. The devices can update the cache line in the local copy of the shared memory as data is processed as received over the optical communication link.
