  • Patent number: 12242424
    Abstract: A memory tier including persistent memory (PMEM) devices is established in nodes of a cluster system having a deduplicated file system. At least a portion of metadata generated by the deduplicated file system is persisted to the memory tier. The portion of metadata includes an index of fingerprints corresponding to data segments stored by the deduplicated file system to a storage pool. A determination is made that an instance of the deduplicated file system has failed. A new instance of the deduplicated file system is started to recover file system services by loading the index of fingerprints from the memory tier.

  • Patent number: 12235897
    Abstract: Methods and apparatuses for multimodal enhancement of interactions in conversation service applications include a server that establishes a chat-based communication session between a conversation service application and a client computing device. Query input is captured from a user during the session. The server converts an audio segment corresponding to a video into a video transcript using speech recognition, and determines a transcript portion for the video that is responsive to the query input using a dense passage retriever model. The server selects video frames from the video that correspond to the transcript portion and determines, for the selected frames, a predicted relevancy between the selected frame and the query input. The server generates a response to the query input comprising the selected frames based upon the relevancy. The server transmits the response to the client device for display.

  • Publication number: 20240344272
    Abstract: The present invention relates to compositions and methods for forming substantially bio-based barrier coatings suitable for application on paper and board substrates, and paper and board substrates on which are applied one or more layers of such substantially bio-based barrier coatings. The inventive bio-based barrier coatings comprise a biowax emulsion comprising one or more biowaxes, such as castor oil wax, formed by hydrogenation of a bio-based oil, such as castor oil. The barrier coating composition is formed by dispersing a biowax emulsion into a polyhydroxyalkanoate (PHA) dispersion, and may be applied as a coating e.g., on paper or board, e.g., those comprised of recycled fibers, using conventional industrial methods at ambient temperatures.

  • Patent number: 11829249
    Abstract: A memory tier is established in a cluster system having a deduplicated file system. The memory tier includes memory pages configured as huge pages, where writes to the huge pages are exported in a device file that is outside of a user process namespace within which processes of the deduplicated file system run. At least a portion of metadata generated by the deduplicated file system is written to the memory tier. The portion of metadata includes an index of fingerprints corresponding to data segments stored by the deduplicated file system to a storage pool. A determination is made that an instance of the deduplicated file system has failed. A new instance of the deduplicated file system is started to recover file system services by loading the index of fingerprints from the device file.

  • Patent number: 11775438
    Abstract: System identifies multiple data blocks in workload stored in slow access persistent storage, data blocks copied to fast access persistent storage, and, after speed of accessing workload satisfies threshold, copied data blocks that remained in fast access persistent storage. System annotates some remaining data blocks with cache label and derives features for some data blocks in workload, based on corresponding bits set and/or time stamp. System uses cache labels and features for some data blocks in workload to train machine-learning model to predict which data blocks in workload will remain in fast access persistent storage after workload access satisfies threshold. System derives features for data block requested from production workload.

  • Patent number: 11709667
    Abstract: In a symmetric hardware accelerator system, an initial hardware accelerator is selected for an upgrade of firmware. The initial and other hardware accelerators handle workloads that have been balanced across the hardware accelerators. Workloads are rebalanced by directing workloads having low CPU utilization to the initial hardware accelerator. A CPU fallback is conducted of the workloads of the initial hardware accelerator to the CPU. While the CPU is handling the workloads, firmware of the initial hardware accelerator is upgraded.

  • Patent number: 11546139
    Abstract: A method, apparatus, and system for assigning the execution of a cryptography and/or compression operation on a data segment to either a central processing unit (CPU) or a hardware accelerator is disclosed. In particular, a data segment on which a cryptography and/or compression operation is to be executed is received. Status information relating to a CPU and a hardware accelerator is determined. Whether the operation is to be executed on the CPU or on the hardware accelerator is determined based at least in part on the status information. In response to determining that the operation is to be executed on the CPU, the data segment is forwarded to the CPU for execution of the operation. On the other hand, in response to determining that the operation is to be executed on the hardware accelerator, the data segment is forwarded to the hardware accelerator for execution of the operation.
