Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] A hierarchical storage system for supercomputer operation data includes a three-tier storage system set in the supercomputer, and the three-tier storage system is respectively a high-speed storage layer, an online storage layer and a near-line storage layer. like figure 2 As shown, since supercomputer users generally manage job data through login nodes, and job tasks run through computing nodes, the high-speed storage layer mounts general computing nodes; the online storage layer mounts login nodes and small and micro job computing nodes. The user's job data is stored in the online storage layer, and the user can manage the job data by logging in to the node; when a job needs to be run, the job data is copied from the online storage layer to the high-speed storage layer through the "job copy return mechanism". . At the same time, for smaller job tas...

Abstract

The invention relates to a hierarchical storage system and method for supercomputer operation data. By dividing the storage layer into a three-layer storage system including a high-speed storage layer, an online storage layer and a near-line storage layer, the three-layer storage system is respectively constructed. The operation data copy and return mechanism, the original data retention time calculation mechanism and the operation data automatic archiving and exchange mechanism, and the integration of the supercomputer system and the three-tier storage system realize the solution under the premise of controlling the overall equipment cost of the storage system. It solves the contradiction between user operation data storage space, access performance and equipment cost of the supercomputer system. While maintaining the low cost of storage equipment, it improves the total available space of the storage system and the IO performance of storage services, increases the total available storage space of data, and reduces The average cost of storage system equipment.

Description

technical field [0001] The invention belongs to the field of supercomputer storage, in particular to a system and method for layered storage of supercomputer operation data. Background technique [0002] With the continuous development of high-performance computing technology, the computing performance that supercomputers can provide is getting stronger and stronger. More and more researchers are using supercomputers to run their own operations to reduce operation time and improve scientific research work. efficiency. However, during the same period, the development speed of the underlying storage system of the supercomputer was relatively flat. With the continuous improvement of the computing performance of the supercomputer, the supporting storage system began to be unable to cope with it. When running high IO computing jobs, the storage system began to become a The bottleneck of the entire high-performance computing system restricts the further improvement of the perform...
