Abstract

The invention discloses a method, a device and a system for collecting rubbish of multiple scheduling virtual machines in a scheduling cluster environment. The scheduling method comprises the following steps: firstly, receiving internal memory use reports from the multiple virtual machines; then scheduling activities for collecting rubbish in the multiple virtual machines in the form of issuing tokens based on the received internal memory use reports.With the method and device of the invention adopted, synchronous rubbish collection of multiple virtual machines can be avoided, thus improving real-time property of the cluster system while basically not reducing internal memory use ratio.

Description

Technical field [0001] The present invention generally relates to a method and device for coordinating garbage collection among multiple applications in a cluster environment, and more specifically to a method and device for actively scheduling garbage collection time within multiple applications in a cluster environment. Background technique [0002] The Garbage Collection (GC) mechanism is a common feature of a new generation of languages ​​such as Java, C#, Python, Eiffel, Roby, etc. Through this garbage collection mechanism, the recovery of memory can be automatically managed without the programmer calling functions to release the memory, thus reducing the programmer's programming burden. [0003] At present, application servers of cluster architecture, such as application servers based on Java and C#, are widely used in large-scale applications such as telecommunications services. For example, the Java language has the advantages of being easy to learn and write, independent ...
