Systems and methods may provide a set of networked computational resources such as nodes that may be arranged in a hierarchy. A hierarchy of performance balancers receives performance samples from the computational resources beneath them and uses the performance samples to conduct a statistical analysis of variations in their performance. In one embodiment, the performance balancers steer power from faster resources to slower resources in order to enhance their performance, including in parallel processing.

Dynamic hierarchical performance balancing of computational resources

Apparatus and methods may provide for characterizing a plurality of similar components of a distributed computing system based on a maximum safe operation level associated with each component and storing characterization data in a database and allocating non-uniform power to each similar component based at least in part on the characterization data in the database to substantially equalize performance of the components.

Mitigating component performance variation

Systems and methods may provide a set of cores capable of parallel execution of threads. Each of the cores may run code that is provided with a progress meter that calculates the amount of work remaining to be performed on threads as they run on their respective cores. The data may be collected continuously, and may be used to alter the frequency, speed or other operating characteristic of the cores as well as groups of cores. The progress meters may be annotated into existing code.
