摘要： A solution is proposed for managing containers isolating corresponding application environments from one or more shared operating systems in a computing system. One or more relevant groups are determined among one or more candidate groups (each comprising private data in common among a plurality of the containers); the candidate groups are determined according to corresponding access commands submitted by the containers and the relevant groups are determined according to one or more relevance policies. The private data of the relevant groups are consolidated into corresponding shared data.

摘要： The present invention provides a vehicle control device capable of realizing access authority definitions by the number equal to or greater than the number of access control registers provided in a memory protection device. In the vehicle control device according to the present invention, the whole or a part of a storage device that stores the access authority definitions used by the memory protection device to control the access authorities, is allocated fixedly to a memory area in advance and the rest is allocated dynamically.

摘要： A secure electronic device is disclosed. The secure electronic device includes a first core processing unit, a secure boot Read-Only Memory, a first non-volatile memory, a first volatile memory and a first communication interface. A new framework based on the secure electronic device with built-in security is able to safeguard intellectual property for the developers and further improves the security of the secure electronic device. Thus, more developers can launch their programs or services without being stolen or tampered by an unauthorized party.

摘要： Method, system and product for direct access to de-duplicated data units in memory-based file systems. The method comprising: updating a page entry in a page table of a process to include a direct access pointer to a de-duplicated data unit retained by the memory-based file system, wherein the page entry is set to be write protected; detecting a page fault occurring due to the process performing a store instruction to the de-duplicated data unit; and in response to said detecting: allocating a new data unit; copying content of the de-duplicated data unit to the new data unit; and replacing the direct access pointer to the de-duplicated data unit with a direct access pointer to the new data unit.

摘要： A method is described that includes detecting that an instruction of a thread is a locked instruction. The instruction also includes determining that execution of said instruction includes imposing a bus lock. The instruction also include executing a bus lock assistance function in response to said determining, said bus lock assistance function including a function associated with said bus lock other than implementation of a bus lock protocol.

摘要： A computer-implemented method includes the following operations. A transactional lock elision transaction including a critical section is executed. The critical section is processed. After the processing of the critical section and prior to a commit point in the transactional lock elision transaction, a status of a lock is checked. Responsive to a determination that a status of the lock is free, a result of the transactional lock elision transaction is committed.

摘要： A method for managing access of virtual machines executed by a host computer system to storage area networks, the storage area networks connecting the host computer system with storage systems via switches, where the host computer system includes one or more host ports to connect with a switch each, and where one or more port names are assigned to each virtual machine. The method includes, for each storage area network connected with the host computer system, sending the port names of a virtual machine and a target port name as part of a validate access command to the respective switch; and when receiving the validate access command by the switch, the switch returning success information to the sending host computer system in case all received virtual machine port names have access to a target port assigned to the received target port name, otherwise returning a fail information.

摘要： The systems and methods disclosed herein transparently provide an improved scalable cloud-based dynamically adjustable or configurable storage volume. In one aspect, a gateway provides a dynamically or configurably adjustable storage volume, including a local cache. The storage volume may be transparently adjusted for the amount of data that needs to be stored using available local or cloud-based storage. The gateway may use caching techniques and block clustering to provide gains in access latency compared to existing gateway systems, while providing scalable off-premises storage.
