Abstract: A high-performance computing-oriented method for automatically deploying an execution environment along with a job, including: presetting isolated execution environments at nodes of a high-performance computing system; logging in an isolated execution environment of a login node; carrying out development and debugging on the job and configuration on a job execution environment at the login node, and issuing a job running request to a job management system; assigning compute nodes from the nodes of the high-performance computing system to the job of the user by the job management system, automatically deploying an file system of the user synchronously to the assigned compute nodes along with the job when the job is loaded, and running the job of the user by the corresponding compute nodes; and feeding results back to the login node of the user after running the job is completed, then clearing file systems.

Abstract: The distance measuring apparatus includes a light source, a beam splitter, a lens group comprising at least one dispersion lens, a first light limiter and a spectrum sensor. The light source is configured to emit detection light. The beam splitter is configured to transmit the detection light. The lens group is configured to disperse the transmission light to the lens group to focus the light of different wavelengths to different positions. The first light limiter is provided with a light passing area. The first reflected light represents reflected light generated on a second surface when second reflected light is transmitted from the lens group to the second surface of the beam splitter, and the second reflected light represents reflected light generated on the surface of a measured object by light focused on the surface of the measured object.

Abstract: A method and system for constructing a lightweight container-based user environment (CUE), and a medium, the method including: preparing, by a main process, for communication, cloning a child process, and then becoming a parent process; elevating, by the child process, permission, executing namespace isolation, and cloning a grandchild process, and setting, by the parent process, cgroups for the grandchild process; and setting, by the grandchild process, permission of the grandchild process to execute a command and a file, preparing an overlay file system, setting a hostname, restricting permission, and executing an initialization script to start the container. Multiple users are allowed to customize their own environments, enabling the users to customize their environments more flexibly, achieving privacy isolation, and making it easier and more secure to update a system. Therefore, it is particularly applicable to a high-performance computing cluster.
