Problems solved by technology
[0003] Due to the continuous evolution of low-latency, high-bandwidth network interconnection technologies, the distributed shared memory system has reduced the performance gap between intra-node and inter-node memory access. Currently, remote direct data access (RDMA, Remote Direct Memory Access) technology for remote memory access, but the distributed shared memory system using this technology still has serious network delay and other problems, which limits the performance of the distributed shared memory system

The embodiment of the invention provides a data processing method and device based on a distributed shared memory system, the distributed shared memory system is provided with a plurality of hosts, the method comprises the steps of presetting a public memory pool, the public memory pool is obtained by combining public memory spaces of the hosts in the distributed shared memory system, each host supports a fast computing link protocol; receiving a first access request of a first host for a first memory address in the public memory pool, wherein the first access request is an access request of a memory protocol based on a fast computing link; converting the first access request into a second access request, wherein the second access request is an access request of a cache protocol based on a fast computing link; and according to a preset address mapping table, mapping the first memory address to a second memory address in the second host so as to access the second memory address according to the second access request, thereby realizing the distributed shared memory system for quickly calculating the link protocol.
Description
technical field [0001] The invention relates to the technical field of computer architecture, in particular to a data processing method and device based on a distributed shared memory system. Background technique [0002] With the development of science and technology, the Distributed Shared Memory (DSM, Distributed Shared Memory) system has received more and more attention, because it can provide a logically unified memory abstraction for physically distributed memory, greatly enhancing the scalability of the memory system. [0003] Due to the continuous evolution of low-latency, high-bandwidth network interconnection technologies, the distributed shared memory system has reduced the performance gap between intra-node and inter-node memory access. Currently, remote direct data access (RDMA, Remote Direct Memory Access) technology for remote memory access, but the distributed shared memory system using this technology still has serious problems such as network delay, which ...
