    Abstract: A data object may be moved from a source data store to a destination data store via replication. The replication is initiated when an original data object in a source data store that is capable of being both read from and being written to is read. Following the read, the original data object is then duplicated to a destination data store. The duplicate data object is provided with a state that indicates the duplicate object is duplicated from the source data store and can be read but cannot accept a data write. Subsequently, the state of the original data object is changed to can be read but cannot be written to using optimistic locking. Further, the state of the duplicate data object is also modified to being capable of both read from and written to with the use of optimistic locking. The replication is completed with the deletion of the original data object from the source data store.

    Abstract translation: 可以通过复制将数据对象从源数据存储移动到目的地数据存储。 当源数据存储器中的能够被读取和写入的原始数据对象被读取时，启动复制。 在读取之后，原始数据对象然后被复制到目的地数据存储。 复制数据对象被提供有指示从源数据存储器复制重复对象并且可以被读取但不能接受数据写入的状态。 随后，将原始数据对象的状态更改为可以读取，但不能写入使用乐观锁定。 此外，重复数据对象的状态也被修改为能够使用乐观锁定来读取和写入。 通过从源数据存储中删除原始数据对象来完成复制。

    Abstract: The present disclosure provides a method, computer program product, and activity recording system for identifying idleness in a processor via a concurrent software environment. A thread state indicator records an indication of a synchronization state of a software thread that is associated with an identification of the software thread. A time profiler identifies a processor of the computer system being idle and records an indication that the processor is idle. A dispatch monitor identifies a dispatch of the software thread to the processor. In response to the dispatch monitor determining the indication identifies that the processor is idle and the indication of a synchronization state of the software thread indicating the software thread ceases to execute in the processor, the dispatch monitor generates a record attributing the idleness of the processor to the software thread and the indicated synchronization state.

    Abstract: A method for distributing IO load in a RAID storage system is disclosed. The RAID storage system may include a plurality of RAID volumes and a plurality of processors. The IO load distribution method may include determining whether the RAID storage system is operating in a write-through mode or a write-back mode; distributing the IO load to a particular processor selected among the plurality of processors when the RAID storage system is operating in the write-through mode, the particular processor being selected based on a number of available resources associated with the particular processor; and distributing the IO load among the plurality of processors when the RAID storage system is operating in the write-back mode, the distribution being determined based on: an index of a data stripe, and a number of processors in the plurality of processors.

    Abstract: Various embodiments for facilitating search, list and retrieval operations on a persistent data set using a distributed shared memory (DSM) by a processor device are provided. In one exemplary embodiment, a DSM is used to store the data structures in a cluster shared memory, such that updates, deletions and insertions are applied to both the persistent data set and the DSM, and search, list and retrieval operations are processed directly from the DSM. A data structure in the persistent data set is stored in two separate DSM pages: a first page includes an identifying search key of the data structure, the search key also pointing to a location of the data structure in the storage. A second page includes the updatable properties of the data structure. A DSM storing the data structures' pages is organized as a two-row matrix.
