DIRECT SWAP CACHING WITH ZERO LINE OPTIMIZATIONS: abstract simplified (17718920)

• This abstract for appeared for patent application number 17718920 Titled 'DIRECT SWAP CACHING WITH ZERO LINE OPTIMIZATIONS'

Simplified Explanation

The abstract describes a method for managing a computer system with two types of memory: near memory and far memory. When a request is made to read a block of data, the method analyzes the metadata associated with the block. The metadata contains information about whether the block is stored in the near memory or far memory, as well as whether the data in the block is all zeros. Instead of retrieving the data from the far memory, the method synthesizes the data and sends it to the requester. This approach helps optimize the system's performance by avoiding unnecessary data retrieval.

Original Abstract Submitted

Systems and methods related to direct swap caching with zero line optimizations are described. A method for managing a system having a near memory and a far memory comprises receiving a request from a requestor to read a block of data that is either stored in the near memory or the far memory. The method includes analyzing a metadata portion associated with the block of data, the metadata portion comprising: both (1) information concerning whether the near memory contains the block of data or whether the far memory contains the block of data and (2) information concerning whether a data portion associated with the block of data is all zeros. The method further includes instead of retrieving the data portion from the far memory, synthesizing the data portion corresponding to the block of data to generate a synthesized data portion and transmitting the synthesized data portion to the requestor.
