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: A system that implements a data storage service may store data on behalf of storage service clients. The system may maintain data in multiple replicas of various partitions that are stored on respective computing nodes in the system. The system may employ a single master failover protocol, usable when a replica attempts to become the master replica for a replica group of which it is a member. Attempting to become the master replica may include acquiring a lock associated with the replica group, and gathering state information from the other replicas in the group. The state information may indicate whether another replica supports the attempt (in which case it is included in a failover quorum) or stores more recent data or metadata than the replica attempting to become the master (in which case synchronization may be required). If the failover quorum includes enough replicas, the replica may become the master.

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.

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: One embodiment provides an apparatus. The apparatus includes a processor, a chipset, a memory to store a process, and logic. The processor includes one or more core(s) and is to execute the process. The logic is to acquire performance monitoring data in response to a platform processor utilization parameter (PUP) greater than a detection utilization threshold (UT), identify a spin loop based, at least in part, on at least one of a detected hot function and/or a detected hot loop, modify the identified spin loop using binary translation to create a modified process portion, and implement redirection from the identified spin loop to the modified process portion.

Abstract: A system, method and computer program product to execute a first and a second work-item, and compare the signature variable of the first work-item to the signature variable of the second work-item. The first and the second work-items are mapped to an identifier via software. This mapping ensures that the first and second work-items execute exactly the same data for exactly the same code without changes to the underlying hardware. By executing the first and second work-items independently, the underlying computation of the first and second work-item can be verified. Moreover, system performance is not substantially affected because the execution results of the first and second work-items are compared only at specified comparison points.

Abstract: Providing a computer program product, system, and method for setting copy permissions for target data in a copy relationship. Source data is copied from a first storage to a first data copy in a second storage. A request is received to copy requested data from the first data copy to a second data copy. The second copy operation is performed to copy the requested first data copy form the second storage to a second data copy in response to determining that the requested first data copy is not in the state that does not permit the copying. The request is denied in response to determining that the requested first data copy is in the state that does not permit copying.

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 readable medium and method for providing checkpointing to Windows application groups. The checkpointing may be triggered asynchronously using Asynchronous Procedure Calls. The computer readable medium includes computer-executable instructions for execution by a processing system. The computer-executable instructions may be for reviewing one or more command line arguments to determine whether to start at least one of the application groups, and when determining to start the at least one of the application groups, creating a process table in a shared memory to store information about each process of the at least one of the application groups. Further, the instructions may be for registering with a kernel module to create an application group barrier, creating a named pipe for applications of the application group to register and unregister, triggering a checkpoint thread to initiate an application group checkpoint; and launching an initial application of the applications of the application group.
