Abstract: A rotor rotating device includes at least two rotating units; a movable end of a telescoping cylinder in each rotating unit is provided with a pin; the pin is releasably secured on a rotor. A control method for the rotor rotating device includes: dividing the at least two rotating units into two groups; first removing pins of a first group of rotating units from the rotor, and then re-securing the pins at another positions on the rotor; and after the pins of all the rotating units are re-secured, changing the state of the telescoping cylinders of all the rotating units, and driving the rotor to turn relative to a machine base. In this way, all the rotating units are sequentially unlocked, moved to a next working station, and re-locked on the rotor. A control device, and a rotor rotating system are further provided.

Abstract: A software protection system includes a user terminal and a server. According to an authorization request from the user terminal as to target software, the server generates an encrypted authorization file and an executable file of the target software. When the executable file is to be run at a terminal, a determination is made as to whether the physical information of the terminal and information as to the target software are same as that in the encrypted authorization file. When the information are same, the running of the executable file is permitted. The disclosure further provides a software protection method.

Abstract: Embodiments of the present disclosure provide a method and apparatus for assigning lock resources to objects by obtaining a first alternative lock for the object, and determining first correlations between the object and each of one or more other objects when the first alternative lock has been assigned to the one or more other objects, wherein in response to determining that each of the first correlations is lower than a predetermined threshold, assign the first alternative lock to the object, and may maximize the possibility of parallel execution and reduce the time waiting for lock resources, thereby avoiding lock contention.

Abstract: A method for caching images in a virtual environment uses hash tables to store information about an application or window and to store updated images. Suitable areas of applications or windows are fixed relative to the window for many cases, and also include a relatively small number of possible display statuses. Hash tables are used on an agent side and a client side to track previous image updates. When an updated image is determined to be already stored in a cache, the agent side can transmit a hash identifying the image to the client side, and the client side can update the display with the cached image.

Abstract: Embodiments of the present disclosure disclose a method, an apparatus and a computer program product for failing back block objects in batch by performing failback operations in batch to part of block objects of one or more of existing file systems; determining a delay time required for performing failback operations in a next batch based on the recorded number of block objects that have been failed back in last batches; and performing the failback operations in the next batch to remaining block objects after the delay time.

Abstract: Described are techniques for processing a write operation that writes first data to a target location of a logical address range of a logical device. It is determined whether the target location is mapped to physical storage. Responsive to determining that the target location is not mapped to physical storage, performing first processing to service the write operation. The first processing includes sending the write operation along with a hint to a caching layer where the hint indicates to store zeroes to locations that do not include user data. The caching layer forms a data portion denoting data stored at a logical address subrange of the logical device. The logical address subrange includes the target location. The data portion includes the first data and zeroes stored at remaining locations of the logical address subrange not including user data. The data portion is stored in cache by the caching layer.
