The invention discloses a process scheduling method and computing equipment. The method is executed in an operating system of the computing device, the computing device comprises a plurality of nodes in communication connection, each node comprises one or more processors and an internal memory, each processor is suitable for running a process, the internal memory of the node where the process is located comprises a virtual memory area of the process, and the virtual memory area comprises memory pages. The method comprises the following steps: in response to a request of accessing a memory page by a process, judging whether the memory page is a shared memory page; if yes, whether the number of times that the process continuously accesses the memory page is larger than a first threshold value or not is judged; and if the load is greater than the first threshold value, selecting a processor of which the load meets a preset condition as a target processor from a node where the memory page is located or a node closest to the memory page, and migrating the process to the target processor. According to the technical scheme of the invention, the process can be prevented from accessing the remote memory with a relatively long distance, and the speed of accessing the shared memory by the process is improved.
Description
technical field [0001] The present invention relates to the field of computer technology, and in particular, to a process scheduling method and computing device. Background technique [0002] The basic feature of a NUMA server is that it has multiple CPU modules (nodes), and each CPU module can include one or more CPUs, and has independent local memory, I / O slots, and the like. Since each node can communicate and exchange information through an interconnection module (Crossbar Switch), each CPU can access the memory of the entire system. However, the speed of CPU access to local memory is much higher than that of remote memory (memory of other nodes in the system). [0003] When multiple processes run and communicate on CPUs of different nodes, in order to solve the problem that the shared memory page that the process needs to access and the node where the process is located are located on different nodes, and there is a problem of slow access speed due to cross-node access...
