It is most desirable that the registry files of a local computer platform be in instant synchronism with the registry files of a remote backup computer platform. The present invention provides a component object that can monitor a user-specified registry key on a local computer platform and operate to duplicate that registry key, on an instant update basis, at the remote backup platform whenever the local registry key undergoes a change.

System and method for replicating monitored registry keys

A method is provided to establish affinity for each pair of processors with a specific processor bus which eliminates the need for cross-bus operations in cache invalidation operations. Each pair of processors in the network is exercised for elapsed time of cache update cycle completion. Those pairs having the minimal execution times are then selected for utilization of applications to be executed.

Affinity checking process for multiple processor, multiple bus optimization of throughput

A method in a multi-processor computing system is disclosed. The method is an object-oriented method that allows a user to make associations between processes to be executed and available CPUs of the system. In particular, the method includes the displaying of the associations for a user to manipulate. Responses are accepted by the method from a user for creating logical groupings of the CPUs, hereinafter referred to as affinity groups. Next, an affinity mask is accepted from the user for each of the affinity groups, which affinity mask assigns available ones of the CPUs. After this a determination is made as to whether or not there are more CPUs to be assigned to the affinity groups, and if not; specific rules that make associations between the processes and the affinity groups are then accepted by the method from the user.

System and method for assigning processes to specific CPU's to increase scalability and performance of operating systems

In a system where a remote backup platform is enabled to automatically duplicate each registry key change in a local platform, a method is provided wherein restoration of original remote registry key data can be accomplished by utilizing a remote disk file which stores original data. When local original registry data on the local platform is lost to due breakdown, then a restoration program can access the backup remote registry key data for conveyance to the local registry key.
