Abstract
In a memory access method, a receiver receives a memory access message from a sender in advance, determines an address of the receiver that is used to access a memory of the sender, and determines a mapping relationship between a virtual address and a corresponding physical address. Thus, provided the address of the receiver that is used to access a memory of the sender is registered with a memory region, the receiver may access a memory of the sender.
Claims20
A method implemented by a receiver and comprising:
- receiving, from a sender, a memory access message comprising a sender virtual address of the sender and a receiver virtual address of the receiver;
- and
- accessing a first memory of the sender based on a sender physical address of the sender, a receiver physical address of the receiver, a first mapping relationship mapping the sender virtual address to the sender physical address, and a second mapping relationship mapping the receiver virtual address to the receiver physical address.
A method implemented by a sender and comprising:
- obtaining a memory access message comprising a sender virtual address of the sender and a receiver virtual address of a receiver;
- and
- sending the memory access message to the receiver to prompt the receiver to access a memory of the sender based on a sender physical address of the sender, a receiver physical address of the receiver, a first mapping relationship mapping the sender virtual address to the sender physical address, and a second mapping relationship mapping the receiver virtual address to the receiver physical address.
A receiver comprising:
- one or more processors configured to execute a program code to cause the receiver to:
- receive, from a sender, a memory access message comprising a sender virtual address of the sender and a receiver virtual address of the receiver;
- and
- access a first memory of the sender based on a sender physical address of the sender, a receiver physical address of the receiver, a first mapping relationship mapping the sender virtual address to the sender physical address, and a second mapping relationship mapping the receiver virtual address to the receiver physical address.
