Abstract: This application provides a service deployment method and apparatus. The method includes: determining a first component node that needs to be deployed currently in a to-be-deployed service; obtaining, from a physical cluster, a physical node set that meets a computing resource requirement of the first component node; and obtaining, from the physical node set according to a current available network resource of each physical node in the physical node set, a physical node to which the first component node is mapped. According to the technical solution provided in this application, in a node mapping process of service deployment, that is, in a process of determining a physical node to which a component node is mapped, a computing resource and a network resource are comprehensively considered.

Abstract: Embodiments of the present disclosure relate to a method and a device for enumerating input/output devices (IO devices). The method for enumerating input/output devices includes: acquiring an identifier of each processor and an identifier of each input/output (IO) centralized controller in a system; separately instructing processors to simultaneously enumerate a specific IO centralized controller and an input/output IO device connected to the specific IO centralized controller, according to the identifier of each processor and the identifier of each IO centralized controller; and acquiring related information of IO devices enumerated by the instructed processors. According to the embodiments of the present disclosure, the work of enumerating the system IO devices may be allocated to multiple processors to be carried out simultaneously, so as to greatly reduce time consumed in the enumeration process, and to accelerate a system initialization process.

Abstract: This application relates to the distributed system field, and in particular, to a resource scheduling technology for a distributed system. In a task assignment method, a share of an assigned resource of a user is obtained, a to-be-assigned task is selected from a to-be-assigned task list, and the to-be-assigned task is assigned, based on a maximum threshold, to a first computing node whose remaining resource can meet the to-be-assigned task. In addition, after the to-be-assigned task is assigned to the first computing node, at least one type of monitored resource of the first computing node meets that an amount of the type of remaining monitored resource is greater than or equal to a maximum threshold corresponding to the monitored resource.

Abstract: A file page table management method. The file page table management method is applied to a storage system in which a file system is created in a memory. According to the file page table management method, a mapping manner of a file page table can be dynamically adjusted based on an access type of an access request for accessing the memory, thereby improving memory access efficiency and saving memory space.

Abstract: A file access method and apparatus, and a storage system are provided. After receiving a file access request from a process, a first physical address space is accessed according to a preset first virtual address space and a preset first mapping relationship between the first virtual address space and the first physical address space, where the first physical address space stores a file system. After obtaining an index node of a target file from the first physical address space according to a file identifier of the target file carried in the file access request, a file page table of the target file is obtained according to file page table information. The file page table records a second physical address space in the first physical address space. The target file is accessed according to the second physical address space.
