International Classification:

G06F 1200

US Classification:

711147, 711202

Abstract:

A method and apparatus for performing efficient interprocess communication (IPC) in a computer system. With this invention, a memory region called the IPC transfer region is shared among all processes of the system to enable more efficient IPC. The unique physical address of the region is mapped into a virtual address from each of the address spaces of the processes of the system. When one of the processes needs to transfer data to another of the processes, the first process stores arguments describing the data in the region using the virtual address in its address space that maps into the unique physical address. When the other or second process needs to receive the data, the second process reads the data from the second region using the virtual address in its memory space that maps into the unique physical address. With this invention, in most cases, control of the IPC transfer region occurs automatically without any kernel intervention.

Abstract:

A method for allowing a content provider to restrict access to data without having to trust a service provider. With this invention a content provider is able to restrict access to data to a specific client using a specific machine. A content provider generates a first key which is used to encrypt a second key where the second key will only be encrypted if the user has a one-time password. The encrypted second key is then stored on the client machine. When the user desires to access the data of the content provider, the second key is decrypted and used to access the data.

US Classification:

712228, 718108

Abstract:

A method and system for efficient context switching are provided. An execution entity that is to be context switched out is allowed to continue executing for a predetermined period of time before being context switched out. During the predetermined period of time in which the execution entity continues to execute, the hardware or an operating system tracks and records its footprint such as the addresses and page and segment table entries and the like accessed by the continued execution. When the execution entity is being context switched back in, its page and segment table and cache states are reloaded for use in its immediate execution.

US Classification:

717168, 719332

Abstract:

To dynamically update an operating system, a new factory object may have one or more new and/or updated object instances. A corresponding old factory object is then located and its version is checked for compatibility. A dynamic update procedure is then executed, which includes (a) changing a factory reference pointer within the operating system from the old factory object to the new factory object. For the case of updated object instances, (b) hot swapping each old object instance for its corresponding updated object instance, and (c) removing the old factory object. This may be performed for multiple updated object instances in the new factory object, preferably each separately. For the case of new object instances, they are created by the new factory and pointers established to invoke them. A single factory object may include multiple updated objects from a class, and/or new object instances from different classes, and the update may be performed without the need to reboot the operating system.

Abstract:

A system, method and computer program product for monitoring availability of end user devices needed for performing tasks. The system comprises a first network including one or more devices associated with an end user, at least one device adapted for communicating with a service provider over a second network, the service provider providing network-based services in the system. The system includes a memory storage device for maintaining information of tasks associated with an end user, the information including recommended end-user devices adapted to perform the tasks, the information being accessible to at least one end-user device. At least one end-user device detects non-availability or performance deficiencies of any end-user device required in performing end-user tasks, and communicates with the service provider for invoking network-based services to facilitate correcting non-availability of any end-user device. Such a system, method and computer program product enables students to receive these reminders and alerts, to order the necessary upgrades from suppliers via web services, and to monitor delivery from a single user interface provided on one of their devices.

International Classification:

G06F 19/00

US Classification:

702 61

Abstract:

Real world energy usage can be reduced using a virtual environment. A virtual universe energy conservation system (“system”) can determine comprehensive energy usage at a physical site where a client accessing a virtual universe is located. The system can determine that the comprehensive energy usage at the physical site exceeds an energy usage threshold. The system can also notify a virtual universe user account associated with the client that the comprehensive energy usage at the physical site exceeds the energy usage threshold.

US Classification:

709232, 709228

Abstract:

In an embodiment, a send thread receives an identifier that identifies a destination node and a pointer to data. The send thread creates a first send request in response to the receipt of the identifier and the data pointer. The send thread selects a selected channel from among a plurality of channels. The selected channel comprises a selected hand-off queue and an identification of a selected message unit. Each of the channels identifies a different message unit. The selected hand-off queue is randomly accessible. If the selected hand-off queue contains an available entry, the send thread adds the first send request to the selected hand-off queue. If the selected hand-off queue does not contain an available entry, the send thread removes a second send request from the selected hand-off queue and sends the second send request to the selected message unit.

Abstract:

A device for copying performance counter data includes hardware path that connects a direct memory access (DMA) unit to a plurality of hardware performance counters and a memory device. Software prepares an injection packet for the DMA unit to perform copying, while the software can perform other tasks. In one aspect, the software that prepares the injection packet runs on a processing core other than the core that gathers the hardware performance counter data.
