Problems solved by technology

Such an architecture not only cannot take advantage of the latest virtual machine management software, but also brings huge complexity when adjusting the distributed system architecture, making it difficult to achieve real-time allocation of resources
At the same time, the distributed shared memory based on the traditional network has a bottleneck in the transmission speed, which limits the scalability of the system

Abstract

The invention provides a realization method for a cross-physical-machine huge virtual machine. The method comprises the steps that first, a huge virtual machine is created; second, interrupt processing is performed on the huge virtual machine; third, equipment interrupt processing is performed; and fourth, remote access based on a high-speed shared memory access technology is performed. Through the method, multiple physical machines provide computing resources, IO resources and other resources for one virtual machine; and the machines perform remote memory access through the remote high-speed memory access technology, so that a high-speed distributed shared memory is realized.

Description

technical field [0001] The invention relates to a method for realizing a giant virtual machine, in particular to a method for realizing a giant virtual machine (Giant VM) across physical machines. Background technique [0002] Virtualization refers to virtualizing a physical computer into multiple logical computers through virtualization technology. Each logical computer can run a different operating system independently of each other, providing a logical view of data, computing power, storage, and other resources. With the development of fields such as machine learning, people have put forward higher requirements for the performance of virtual machines, and the resources of a single physical computer, including CPU, memory and other devices (such as GPU, FPGA), etc., can no longer meet the requirements. It is a feasible solution to virtualize multiple physical machines into a single virtual machine (referred to as "multiple virtual one") so that the virtual machine has mas...
