Abstract: Methods and systems for a copy-offload operation are provided. A soft range lock is placed for a data container for generating a token for a copy-offload operation for copying the data container from a source location to a destination location, where presence of the soft range lock indicates that content of the data container has not changed during the copy-offload operation. A token for the copy-offload operation represents the content of data container and includes information regarding the soft range lock. The token with the soft range lock information is provided to the client that requests the copy-offload operation. If the soft range lock exists, then the data container is copied without using a point in time copy of the data container.

Abstract: In response to an instruction to dismount a storage volume, for example, an object in the storage volume is identified and a handle that references the object is closed. Once an exclusive lock on the storage volume is acquired, the storage volume can be dismounted. The storage volume can then remounted.

Abstract: Implementations are disclosed for a centralized peripheral access controller (PAC) that is configured to protect one or more peripheral components in a system. In some implementations, the PAC stores data that can be set or cleared by software. The data corresponds to an output signal of the PAC that is routed to a corresponding peripheral component. When the data indicates that the peripheral is “unlocked” the PAC will allow write transfers to registers in the peripheral component. When the data indicates that the peripheral component is “locked” the PAC will refuse write transfers to registers in the peripheral component and terminate with an error.

Abstract: One or more embodiments may provide a method for performing a replay. The method includes initiating execution of a program, the program having a plurality of sets of instructions, and each set of instructions has a number of chunks of instructions. The method also includes intercepting, by a virtual machine unit executing on a processor, an instruction of a chunk of the number of chunks before execution. The method further includes determining, by a replay module executing on the processor, whether the chunk is an active chunk, and responsive to the chunk being the active chunk, executing the instruction.

Abstract: A transactional memory system salvages a hardware lock elision (HLE) transaction. A processor of the transactional memory system executes a lock-acquire instruction in an HLE environment and records information about a lock elided to begin HLE transactional execution of a code region. The processor detects a pending point of failure in the code region during the HLE transactional execution. The processor stops HLE transactional execution at the point of failure in the code region. The processor acquires the lock using the information, and based on acquiring the lock, commits the speculative state of the stopped HLE transactional execution. The processor starts non-transactional execution at the point of failure in the code region.

Abstract: A computer-implemented method, carried out by one or more processors, for a modified asynchronous replication session. In an embodiment, the method comprises the steps of acquiring a lock on a volume configuration, where the lock prevents changes to the volume configuration between a first volume and a second volume at a remote site. Internal control block information is updated, where the update includes at least a volume serial number of the first volume matching a volume serial number of the second volume. Responsive to updating internal control block information, the acquired lock is released to allow changes to the volume configuration.

Abstract: Storage access requests are received from one or more applications. Multiple servers update multiple virtual disks as directed by the storage access requests. The virtual disks store data that is write order dependent across the virtual disks. Logs are associated with the virtual disks. Information associated with each storage access request is stored in one of the logs. A cycle of log switching is performed. A write order consistent tracking coordinator coordinates the log switching with agents at the servers to maintain request ordering. Replication coordinators coordinate the application of the switched-out log files from primary storage to replica storage, creating a write-order consistent point on the replica side matching the primary side, and providing for failure resiliency regarding transfer of the logs. The replication logs may be received individually on the replica side from the servers on the primary side to enable highly scalable parallel/simultaneous transfers of the logs.

Abstract: A transactional memory system salvages a hardware transaction. A processor of the transactional memory system records information about an about-to-fail handler for transactional execution of a code region, and records information about a lock elided to begin transactional execution of the code region. The processor detects a pending point of failure in the code region during the transactional execution, and based on the detecting, stops transactional execution at a first instruction in the code region and executes the about-to-fail handler using the information about the about-to-fail handler. The processor, executing the about-to-fail handler, acquires the lock using the information about the lock, commits speculative state of the stopped transactional execution, and starts non-transactional execution at a second instruction following the first instruction in the code region.

Abstract: Embodiments of the invention relate to supporting transaction data committed to a stable storage. Committed data in the cluster is stored in the persistent cache layer and replicated and stored in the cache layer of one or more secondary nodes. One copy is designated as a master copy and all other copies are designated as replica, with an exclusive write lock assigned to the master and a shared write lock extended to the replica. An acknowledgement of receiving the data is communicated following confirmation that the data has been replicated to each node designated to receive the replica. Managers and a director are provided to support management of the master copy and the replicas within the file system, including invalidation of replicas, fault tolerance associated with failure of a node holding a master copy, recovery from a failed node, recovered of the file system from a power failure, and transferring master and replica copies within the file system.
