[0002] With the development of the Internet and cloud computing, more and more threads are migrated from local to cloud data center servers. In order to reduce the hardware overhead of data center servers and improve the resource utilization of data center servers, multiple The strategy of thread mixed deployment is to deploy multiple threads in the same data center server. Since multiple threads in the mixed deployment need to share the software and hardware resources (that is, shared resources) in the data center server, resource competition occurs, resulting in mixed Unpredictability of deployed thread performance will seriously affect the service quality of target threads (such as high-priority threads)

Embodiment Construction
[0038] see first figure 1 , figure 1 is a schematic structural diagram of a shared resource allocation system according to an embodiment of the present application, such as figure 1 As shown, the shared resource allocation system 100 includes a target thread 102 , a non-target thread 103 , a shared resource 300 and a shared resource allocation device 200 .
[0039] In the embodiment of the present application, the target thread 102 refers to the thread that needs to guarantee the quality of service, and it has a small requirement on the delay, and it needs to ensure that the shared resources occupied by it are sufficient. The non-target thread 103 refers to the thread that does not need to guarantee the quality of service. The delay requirement can be greater than that of the target thread, and the shared resources occupied by the non-target thread 103 can be sacrificed on the premise of ensuring the service quality of the target thread 102 .
[0040] Specifically, the targe...

A method and apparatus for allocate shared resource are provided in embodiments of that present application, The method comprises: Detects and counts the working state of a shared resource when multiple threads are simultaneously accessing the shared resource, The count value is read to obtain the number of base clock cycles, the number of waiting clock cycles and the number of interfering clock cycles, wherein the number of base clock cycles is a count value of the shared resource in the first state, The number of waiting clock cycles is the count value of the shared resources in the second state, and the number of interference clock cycles is the count value of the shared resources in the third state. According to the number of basic clock cycles, the number of waiting clock cycles and the number of interference clock cycles, the allocation quota of the shared resources of the target thread is adjusted, thereby ensuring the quality of service of the target thread.
Description
technical field [0001] The present application relates to the field of information technology, in particular to a method and device for allocating shared resources. Background technique [0002] With the development of the Internet and cloud computing, more and more threads are migrated from local to cloud data center servers. In order to reduce the hardware overhead of data center servers and improve the resource utilization of data center servers, multiple The strategy of thread mixed deployment is to deploy multiple threads in the same data center server. Since multiple threads in the mixed deployment need to share the software and hardware resources (that is, shared resources) in the data center server, resource competition occurs, resulting in mixed Unpredictability of deployed thread performance will seriously affect the service quality of target threads (such as high-priority threads).
