Techniques are provided for parsing files using node objects within a pool. Conventional techniques for parsing files, such as extensible markup language log files, may not efficiently parse the files, and thus cannot keep up with a rate at which the files are generated and / or populated (e.g., a storage system may generate a significant amount of log data stored in log files over time). The disclosed parsing technique is capable of more efficiently processing the files utilizing less memory and time. In particular, the files are parsed by threads that use node objects within a pool of memory (e.g., a sync pool) to store data being parsed and processed by the threads in parallel. When a thread finishes using a node object, the node object is cleared and returned to the pool for subsequent use by the thread or a different thread, which is memory efficient.

A heterogeneous computing system performs data synchronization. The heterogeneous computing system includes a system memory, a cluster, and a processing unit outside the cluster. The cluster includes a sync circuit, inner processors, and a snoop filter. The sync circuit is operative to receive a sync command indicating a sync address range. The sync command is issued by one of the processing unit and the inner processors. The sync circuit further determines whether addresses recorded in the snoop filter fall within the sync address range. In response to a determination that a recorded address falls within the sync address range, the sync circuit notifies a target one of the inner processors that owns a cache line having the recorded address to take a sync action on the cache line.

A storage device may maintain consistent guaranteed performance throughout the life span of the storage device. The storage device includes a data path from a host to a memory device and the data path includes sync points at components along the data. A calibrated time between adjacent sync points on a data path is measured and stored. During use, a controller determines that an event triggering less than the guaranteed performance on the storage device has occurred. The controller measures the calibrated time against a current time associated with the adjacent sync points. When the controller determines that a variance exists between the calibrated time and the current time, the controller applies a corrective measure to retune a data path parameter. The controller uses the retuned parameter to test a calibrated timer on the data path to maintain the guaranteed quality-of-service of the storage device.

The described technology is generally directed towards automatic storage of data / digital objects in a self-adaptive replication system. Data replication can be switched between synchronous (sync) replication and asynchronous (async) replication between a local storage system and a remote storage system. Latency between writing data to the local storage system and the remote storage system can be determined.

Accordingly, data replication can adapt based on infrastructure, volume of data to be write, period(s) of no-data writes, etc. Async replication can use a buffer to temporarily store data during a write operation at the remote storage system. Alternatively, a list can be maintained for data to write to the remote storage system for subsequent replication.

Disclosed herein is a system and method to synchronize files from a hosted file system where the client endpoint devices have direct access to the files stored on a hosted file store. When the client desires to synchronize with the files stored on the hosted file store the process identifies a sync role that can process the request. The particular sync role does not need to maintain state with the client device or the file store. The state necessary for the processing of the synchronization process is maintained separate from the sync role such that any sync role in the system can pick up the requests and process the requests. Once the role has been selected the synchronization process proceeds as normal. As state is not maintained by the sync role multiple roles can process the request or two roles can handle different portions of the process.

A sync tool reorganizes or synchronizes a primary path and a secondary path. The sync tool receives the primary path and the secondary path from the user and determines differences between (a) primary folders and primary files at the primary path and (b) secondary folders and secondary files at the secondary path. The sync tool generates a set of actions based on the differences to reorganize or synchronize the primary path and the secondary path. Prior to reorganizing or synchronizing, the sync tool interacts with the user to edit the set of actions and then implement the set of actions to reorganize and / or synchronize the primary path and the secondary path.
