An apparatus, a method, and a computer program are provided for the generation of constant incremental increases while changing core clock frequencies. The system brings all of the people interactions into a protected, access-controlled environment that allows a patient’s entire continuum of care, inclusive of diagnostic and demographic data, documentation, forms, communication and collaboration, as well as a patient’s transition of care, to be coordinated among as many healthcare providers as are needed for as long as needed. The adjustable tuning circuit may be adjusted by activating a sweep generator that varies a tuning element over a broad frequency range. When the shifting to the cluster restricted mode is completed, one cluster is selected as a cluster to be maintained and the programs to be executed by the processors belonging to the cluster to be maintained are versioned up by new programs.
