Admission control method available for fragmented reservation

Abstract

The invention belongs to core technologies in the field of distributed computing environment resource management and discloses an admission control method available for fragmented reservation. A resource reservation system under a distributed environment mainly comprises a client, a resource provider and a resource scheduler. The resource scheduler is the core of the resource reservation system, possesses dynamic information of each distributed resource, and receives a request sent by the client to judge whether the request can be accepted or not according to latest resource total information. The core concept of the admission control method available for fragmented reservation includes: allowing fragmented reservation of resources on the premise that the maximum fragmentation interval is guaranteed when regular resource reservation fails to realize; and allowing to use the minimum resource quantity for reservation if the rest resource quantity in each fragmentation is smaller than requested reservation resource quantity. By means of the admission control method available for fragmented reservation, resource fragments can be effectively reduced, and resource reservation accepting rate and effective resource utilization rate can be increased.

Description

technical field [0001] The invention relates to a fragmentable reserved admission control method, which belongs to the core technology in the field of distributed computing environment resource management. Background technique [0002] In a high-performance computing grid environment, resources are distributed in different regions and management domains, owned and operated by different organizations, and have different usage policies and security mechanisms, that is, different sites may use different local resources management system. At the same time, many applications need to use resources on multiple sites at the same time. The autonomy of sites, the dynamics and heterogeneity of resources require an effective mechanism to jointly allocate resources on multiple sites. Choosing an appropriate resource management model to effectively manage resources in the computing grid environment is the key to realizing high-performance collaborative computing and jointly accomplishing...
