System and method for dynamic resource access in an asymmetric resource multiple processor computer system

摘要

A system, method and program product enabling applications to be dynamically bound to resources as required by an application. Resource access exceptions are intercepted and, where access is authorized, cause the application to be bound to one of a plurality of processors linked in an asymmetric multiple processor configuration which has access to the resource required. If access is not permitted, an error is generated. Applications may invoke operating system application programming interfaces to register requirements for access to particular resources and to receive operating system feedback on resource assignment conflicts and potential processor thrashing situations. The operating system maintains a list of mapping processors to resources and manages the authorization of resource access by applications. Application processes are dynamically bound to a particular processor as necessary to meet resource requirements. Upon completion of access, the application process is unbound from the processor enabling it to bind to other processors as required for resource access or processor work load balancing.
