Abstract: Techniques are provided for journal replay optimization. A distributed storage architecture can implement a journal within memory for logging write operations into log records. Latency of executing the write operations is improved because the write operations can be responded back to clients as complete once logged within the journal without having to store the data to higher latency disk storage. If there is a failure, then a replay process is performed to replay the write operations logged within the journal in order to bring a file system up-to-date. The time to complete the replay of the write operations is significantly reduced by caching metadata (e.g., indirect blocks, checksums, buftree identifiers, file block numbers, and consistency point counts) directly into log records. Replay can quickly access this metadata for replaying the write operations because the metadata does not need to be retrieved from the higher latency disk storage into memory.

Abstract: Techniques are provided for storage tier verification checks. A determination is made that a mount operation of an aggregate of a set of volumes stored within a multi-tier storage environment has completed. A first metafile and a second metafile are maintained to track information related to the storage of objects of a volume of the aggregate within a remote object store that is a tier of the multi-tier storage environment. A distributed verification is performed between the first metafile and the second metafile to identify an inconsistency. Accordingly, the first metafile and the second metafile are reconciled to address the inconsistency so that storage information within the first metafile and the second metafile are consistent.

Abstract: The current invention provides a novel method to synthesize a mono-disperse non-porous polymer particles with a unique gradient composition from the core to the shell. In particular, the present invention offers the flexibility to design the chemical and physical properties of different sections of the particle. This flexibility allows for significant latitude in the design of particles for analyzing a large variety of samples in different fields—through using these particles in different chromatography techniques including, but not limited to, ion exchange HPLC (e.g., bio-separation at different modes), reversed-phase HPLC, narrow bore and capillary HPLC, hydrophilic/hydrophobic interaction liquid chromatography, capillary electrochromatography separation, and two dimensional liquid chromatography.

Abstract: Techniques are provided for key-value store and file system integration to optimize key value store operations. A key-value store is integrated within a file system of a node. A log structured merge tree of the key-value store may be populated with a key corresponding to a content hash of a value data item stored separate from the key. A random distribution search may be performed upon a sorted log of the log structured merge tree to identify the key for accessing the value data item. A starting location for the random distribution search is derived from key information, a log size of the sorted log, and/or a keyspace size of a keyspace associated with the key.

Abstract: Updating user-specific instances of a second application for individual users of a group based on a data file for the second application being shared via a collaboration object that corresponds to the group within a first application. The instances of the second application present each individual user with their own custom user experience that is configured to provide access to specific content based on object permissions data. An application extension is executable, by the first application, to extend content editing functionalities of the second application into the collaboration object. Responsive to specific content being associated with the collaboration object via the application extension, each of the instances of the second application may be automatically updated to provide direct access to the specific content. Thus, each user within the group defined for collaboration object can access the data file via the collaboration object and their own instance of the second application.

Abstract: Techniques are provided for failing over an aggregate from one file system instance to a different file system instance of a distributed scale-out storage system. The aggregate may be stored within distributed storage that is accessible to a plurality of file system instances of the distributed scale-out storage system. When the aggregate is failed over from a first file system instance to a second file system instance, the first file system instance may still have a valid read lease that allows the first file system instance to serve client I/O, directed to the aggregate, using a cache. In order to prevent the first file system instance from serving stale data from the cache before the read lease expires, state machines and a set of control data are used to ensure that the second file system instance attaches to the aggregate only after the read lease has expired.

Abstract: The present invention relates to (1) a method for producing biochar having bio stimulating effects, (2) biochar that has been produced to having increased bio stimulating effects, (3) a method for capturing material extracted from biochar and (4) biochar extracts, comprising desired compounds extracted from biochar and suspended in an extract solution. The methods above all involve obtaining a particular biomass source and pyrolyzing the biomass source under specific conditions to increase the bio stimulating effects of the biochar. The method for capturing the material extracted from the biochar produced to have such stimulating effects includes contacting the biochar with a treating liquid, separating the biochar from the biochar extract, collecting the biochar extract from which the biochar has been separated and resuspending the biochar extract in an modified aqueous solution for further use and/or processing separate from, or prior to, disposal.

Abstract: Methods and systems for co-locating journaling and data storage are provided. Separate journal and volume partitions may be maintained within each logical storage unit (e.g., Logical Unit Number (LUN)) of a distributed storage system. Journaling of metadata associated with write requests received from one or more clients may be distributed by identifying a destination logical storage unit to which data associated with a given write request is to be stored and causing the data and metadata to be persisted to disk by journaling the metadata and the data to respective portions of an active log within the journal partition of the destination logical storage unit. By using the same logical storage unit for both journaling of write requests and writing the data associated with such write requests, the bottleneck due to there being only a single device or storage unit handling all metadata for all write requests can be avoided.

Abstract: Techniques are provided for multi-tier write allocation. A storage system may store data within a multi-tier storage environment comprising a first storage tier (e.g., storage devices maintained by the storage system), a second storage tier (e.g., a remote object store provided by a third party storage provider), and/or other storage tiers. A determination is made that data (e.g., data of a write request received by the storage system) is to be stored within the second storage tier. The data is stored into a staging area of the first storage tier. A second storage tier location identifier, for referencing the data according to a format utilized by the second storage tier, is assigned to the data and provided to a file system hosting the data. The data is then destaged from the staging area into the second storage tier, such as within an object stored within the remote object store.

Abstract: Systems and methods for performing a zero-copy volume move between nodes of a distributed storage system are provided. In one example, an approach for performing a zero-copy volume move is proposed in which volume data may be maintained in place within a storage pod and need not be copied to move a given volume between the source node and the destination node. In one embodiment, metadata (e.g., a top-most physical volume block number (PVBN) of a node tree representing the volume at issue) of a write-anywhere file system is copied from the source node to the destination node. Since the storage pod is associated with a global PVBN space that is visible and accessible to all nodes of the distributed storage system, as a result of copying the top-mode PVBN of the volume to the destination node, anything below the top-most PVBN will automatically be visible to the destination node.

Abstract: A method, system and computer program product for improving discernment between qubit states in superconducting quantum computers. Channels are calibrated to train the kernel to contain the correct calibration data (“kernel states”). After calibrating a channel, testing is performed in which quantum operations are performed on qubits at the same time in adjacent channels, including the recently calibrated channel, to determine if the kernel response differs from the expected kernel response, where the expected kernel response is based on the kernel states of the trained kernel of the recently calibrated channel, beyond a threshold value. If such a situation occurs, then the phase of the signal for the recently calibrated channel is shifted and the process of recalibrating the channel (using the phase shifted signal) and testing is repeated until the difference between the kernel response and the expected kernel response is not beyond the threshold value.

Abstract: Traditionally, meetings are widely utilized in business and personal communications, whether in-person and/or virtual. Organizing such meetings typically involves multiple exchanges of content and messages between users before, during, and after the meeting. In some cases, meetings may occur impromptu and may result in inefficient and unproductive collaboration. A collaboration object configured to enable users to dynamically collaborate before, during, and after a meeting is provided. In aspects, the collaboration object links content generated before, during, and after the meeting in a single location and provides functionality for concurrent multi-user interaction and synchronization of the content across applications. The collaboration object may be available from a variety of application platforms, enabling and persisting real-time editing and collaboration before, during and after the meeting.
