Some embodiments provide a human and robot distributed operating system (HaRD-OS). The HaRD-OS efficiently and dynamically connects different human operators and algorithms to multiple remotely deployed robots based on the task(s) that the robots are to complete. Some embodiments facilitate an action/perception loop between the operators, algorithms and robots by routing tasks between human operators or algorithms based on various routing polices including operator familiarity, aptitude, access rights, end user preference, time zones, costs, efficiency, latency, privacy concerns, etc. In the event of a fault, some embodiments route to the best operator or algorithm that is able to handle the particular fault with the required privileges. Some embodiments secure task guarantees to be completed at particular times, priorities or costs.

Cooperative Asymmetric Multiprocessing allows for operating systems to function independently of each other on multiple processors sharing common resources in an embedded system. However, some degree of cooperation is required because there are resources with single instances shared across both cores, such as interrupt controller, boot sequencer, DMA engines, etc. The ability to support two distinct operating systems independently gives valuable flexibility. This method allows for reduced complexity in a multi processor system and allows use of existing tools with minimal modifications.

A method and apparatus provides for controlling the distribution and installation of operating systems.

The method and apparatus installs a first operating system into the first partition of the storage device, obtains an image of the second operating system, the image including at least the second operating system pre-configured for operation with the device, and installs, using the first operating system, the image of the operating system to the second partition of the storage device. In an embodiment, the image is transmitted from one or more other devices. In an embodiment, two or more images are cached on the device according to the likelihood they will be used in the future.

An improved distributed operating system over a network of computer systems is described. Existing distributed operating systems have transmission performance limitations dictated by their inability to (1) reliably handle transient communication failures and rapid node reboots, (2) provide a transmission protocol that adapts to link reliability, and (3) allow transmissions to occur over an arbitrary combinations of communication links. The systems and methods described herein solve these problems by providing a reliable node-to-node session protocol that offers high performance message delivery and multi-interface management and support. This is done by transmitting all data between two nodes of the operating system over a single connection that may dynamically exploit multiple interfaces between the nodes.

Described is a service visualizer that presents a high-level view of services currently running in a distributed operating system. The service visualizer, which itself may be a service, is visual-based and uses objects (e.g., spheres) suspended in space to represent the ports of services that are currently running. Messages sent between services are represented by particles. The visualizer creates a visual collection for each service port, which in turn creates a port monitor to watch for messages on the port. The resulting visualization may be interacted with, such as for purposes of debugging.

In general, this disclosure describes techniques of managing resources in a service-oriented distributed computing system. As described in this disclosure, one or more control nodes provide for the efficient and automated allocation and management of resources within the distributed computing system. In order to provide automated allocation and management of computing functions and resources, a control node uses a set of governors. This set of governors includes a set of service governors to govern services used in the distributed computing system. The set of governors also includes a set of resource governors that govern individual resources of the services in the distributed computing system. The service governors and the resource governors may be implemented using finite state machines.
