Embodiment Construction

[0043] The load balancing and node state monitoring method in high-performance computing of the present invention adopts a dynamic feedback load balancing algorithm based on load weights, mainly utilizes factors such as node processing capabilities and actual loads, and proposes concepts such as load weights and load differences , and use this to guide the allocation of tasks, try to make the server nodes do their best, give full play to the advantages of the cluster system, ensure system stability, and improve reliability and availability.

[0044] The dynamic feedback load balancing algorithm mainly uses information such as the load and performance of the server nodes, and through related calculations and methods, distributes the requests of the cluster system to each node as evenly, fairly and reasonably as possible to ensure that each node shares The load is directly proportional to its performance, so that the resources of the system can be fully utilized and the performan...

Abstract

The invention relates to a load balance and node state monitoring method in high performance computing. The method is suitable for reducing resources which occupy a clustering system, increasing the utilization rate of the resources, effectively improving the performance of server clustering and providing high-quality service for a user. The method concretely comprises the steps that firstly, according to the operation state and load and performance parameters of server nodes, computing is performed to obtain load weights of all the nodes, and an alternative node set for next task distribution is selected; afterwards, according to load difference values and distribution probabilities, the probabilities of all node distribution tasks in the alternative node set are computed, and new requests are distributed to the selected nodes in a random probability distribution mode to solve the problem of uneven load distribution; finally, based on a load correction formula, node loads of the distribution tasks are corrected to improve the load balance effect and improve the reliability and stability of the cluster system.

Description

technical field [0001] The invention relates to the field of computer network load balance processing, in particular to a load balance and node state monitoring method in high-performance computing. Background technique [0002] With the increasing popularity of network applications and the rapid growth of Internet services, whether in enterprise networks, campus networks or WANs, the development of business volumes has exceeded past estimates. Enterprises are increasingly dependent on the network, and the application requirements for distributed systems with scalability and reliability are also increasing. When an enterprise provides web services to users, with the rapid increase in the number of visitors, the web server needs to be able to provide a large number of concurrent access services. Its data traffic and calculation intensity are so large that a single device cannot bear it at all; on the other hand, how to achieve a reasonable traffic distribution among multiple...
