A method for conserving resources in a distributed system includes receiving an event-criteria list from a resource controller. The event-criteria list includes one or more events watched by the resource controller and the resource controller controls at least one target resource and is configured to respond to events from the event-criteria list that occur. The method also includes determining whether the resource controller is idle. When the resource controller is idle, the method includes terminating the resource controller, determining whether any event from the event-criteria list occurs after terminating the resource controller, and, when at least one event from the event-criteria list occurs after terminating the resource controller, recreating the resource controller.

Resource conservation for containerized systems

A method includes allocating a first memory location in a non-transitory data store in communication with a computing device and writing data to the first memory location when a first write transaction executes on the non-transitory data store. The method further includes executing one or more read transactions on the first memory location after completion of the first write transaction and incrementing a first pointer counter upon completion of the first write transaction and for each read transaction executing on the first memory location. The method allocates a second memory location in the non-transitory data store and writes updated data to the second memory location when a second write transaction executes on the non-transitory data store to update the data. The first pointer counter decrements and the second pointer counter increments upon completion of the second write transaction. The first memory location de-allocates when the first pointer counter is zero.

Concurrent in-memory data publication and storage system

One embodiment of the present invention provides a system for directing airflow through a computing device. This system comprises an airflow baffle, which includes a set of signal pins and a circuit. The airflow baffle is configured to direct airflow through the computing device, and the set of signal pins are configured to interface the airflow baffle with the computing device. Moreover, the circuit in the airflow baffle is coupled to the set of signal pins, and is configured to use the signal pins to notify the computing device that the airflow baffle is installed in the computing device.

Detectable null memory for airflow baffling

A chassis identification system is described which enables a motherboard in a computer system to identify a type of chassis in which the motherboard is installed. This chassis identification system is composed of a motherboard, a set of conductive fastener mounts on the motherboard, and a sensing circuit on the motherboard that is coupled to the set of conductive fastener mounts. The set of conductive fastener mounts on the motherboard are configured to accommodate different patterns of conductive fasteners which are associated with different types of chassis. Moreover, the sensing circuit on the motherboard is configured to generate a chassis identifier based on a pattern of the conductive fasteners on the chassis.

Automatically detecting a computer chassis type

A method, apparatus and computer program product for providing a device includes incorporating a session ID into the device name. Communication between an application and device is done by way of a pseudo device driver which identifies the appropriate daemon based on the session id, and forwards the data to the daemon where the daemon provides the data to the device. In operations, the system detects a requirement to access a device during a user session and obtains a session identification associated with the user session. A daemon creates a single device node having an identity that indicates the session identification associated with the user session and a pseudo device driver receives a request to access a device from an application associated with the user session. The device driver parses the request to identify the daemon associated with the user session to process the request based on the session identification indicated within the identity of the device as specified in the request to access the device, and then forwards the request to the identified daemon to allow the application to access the device via the single device node.
