    摘要: A computer system is arranged with a circular buffer that includes a piecewise linear map from a high-resolution counter arranged to maintain International Atomic Time. The piecewise linear map includes a current leg that is currently being used and also a future leg that will be used in the future. The future leg is computed while the current leg is still being used.

    摘要: A method and apparatus for and article of manufacture for simulating workloads experienced by multiple partitions in a virtualized system are provided. A master workload driver initiates, coordinates and regulates one or more workload drivers that execute one or more workload simulation tasks in a logical partition. Further, each workload driver may be configured to report a measure of performance regarding the workload to the master control driver where results of many workload drivers may be correlated and analyzed. A configuration file specifies the characteristics of each simulation. Further, the rate and nature of workloads may be adjusted dynamically during a given simulation to model the performance under different real-world scenarios of different computational loads that may be experienced by the virtualized system.

    摘要: A clock offset between a client and a server is measured by: (a) the client sending a request to the server; (b) upon receiving the request in step (a), the server optionally sending a server acknowledgement to the client; (c) upon the client receiving the server acknowledgement in step (b) or directly, if no acknowledgement was used, each of the client and the server proceeding to concurrently exchange their respective timestamps with each other a multiplicity (n) of times, thus forming a multiplicity (n) of timestamp exchanges; and (d) determining a plurality of apparent forwards and backwards delays based on the multiplicity (n) of timestamp exchanges. The preferred apparent forwards and backwards delays are then selected based on the minimum values (for each direction) determined in (d) above. The clock offset between client and server is then determined based on the preferred apparent forwards and backwards delays.

    摘要: An autonomic computing system and method store a set of resource equivalencies in memory, select at least one resource equivalency from the set of resource equivalencies, and use the selected at least one resource equivalency for operating the selected resource as required by an autonomic computing system. The set of equivalent resources can contain a plurality of physically distinct resources that are logically equivalent. Resources are added or removed from the set automatically. Equivalent sets can be nested within an equivalent set.
