Abstract: Bootstrapping a microservices container registry. A computing system node receives an installation package. The receiving computing system node bootstraps an initial invocation of the microservice by first installing a local container registry from the installation package and then by installing the microservice from the installation package. The installation package contains additional components that can be extracted, installed and invoked by executing the microservice at the computing system node after extracting from the local container registry. The installation package is generated by any node of the computing system and contains code corresponding to infrastructure microservices that are installed before invoking microservices that depend on the infrastructure. Temporary domain name services are installed from the installation package at a node-local IP address. The temporary domain name services are switched over to a different domain name service at a different IP address.

Abstract: Methods and apparatus for performing timed functions in battery-powered, wireless electronic devices, such as sensors or control modules. Such electronic devices comprise a main processor and a co-processor. When the main processor enters a quiescent state in order to preserve battery life, one or more timed functions are transferred from the main processor to the co-processor just before the main processor enters the quiescent state. When the co-processor determines that it is time to perform the timed function, the co-processor wakes the main processor in order for the main processor to perform the timed function.

Abstract: Closed loop performance controllers of asymmetric multiprocessor systems may be configured and operated to improve performance and power efficiency of such systems by adjusting control effort parameters that determine the dynamic voltage and frequency state of the processors and coprocessors of the system in response to the workload. One example of such an arrangement includes applying hysteresis to the control effort parameter and/or seeding the control effort parameter so that the processor or coprocessor receives a returning workload in a higher performance state. Another example of such an arrangement includes deadline driven control, in which the control effort parameter for one or more processing agents may be increased in response to deadlines not being met for a workload and/or decreased in response to deadlines being met too far in advance. The performance increase/decrease may be determined by comparison of various performance metrics for each of the processing agents.
