Input/output Data Buffering Patents (Class 710/52)
  • Patent number: 11507309
    Abstract: A storage system and method for using memory allocated in a host for read data as a host memory buffer are provided. In one embodiment, a controller of a storage system receives a read request from a host for data stored in the memory, wherein the read request identifies a storage location in the host that is allocated by the host to store the requested data after it is received from the storage system. Prior to sending the requested data to the host, the storage system uses the allocated storage location in the host as a host memory buffer to store other data until the host needs the allocated storage location to store the requested data. Other embodiments are provided.

  • Patent number: 11503104
    Abstract: A web application has a limit on the total number of concurrent users. As requests from client devices are received from users, a determination is made whether the application can accept those users. When the threshold number of users has been exceeded, new users are prevented from accessing the web application and are assigned to a queue system. A webpage may be sent to the users indicating queue status and may provide their estimated wait time. A cookie may be sent to the client for tracking the position of the user in the application queue. The users are assigned to a user bucket associated with a time interval of their initial request. When user slots become available, the users queued in the user bucket (starting from the oldest user bucket) are allowed access to the web application.

  • Patent number: 11500444
    Abstract: A machine-learning (ML) scheme running a software driver stack to learn user habits of entry into low power states, such as Modern Connect Standby (ModCS), and duration depending on time of day, and/or system telemetry. The ML creates a High Water Mark (HWM) number of dirty cache lines (DL) as a hint to a power agent. A power agent algorithm uses these hints and actual system's number of DL to inform the low power state entry decision (such as S0i4 vs. S0i3 entry decision) for a computing system.

    Abstract: Hardware acceleration of task dependency management in parallel computing, wherein solutions are proposed for hardware-based dependency management to support nested tasks, resolve system deadlocks as a result of memory full conditions in the dedicated hardware memory and synergetic operation of software runtime and hardware acceleration to solve otherwise unsolvable deadlocks when nested tasks are processed. Buffered asynchronous communication of larger data exchange are introduced, requiring less support from multi-core processor elements as opposed to standard access through the multi-core processor elements. A hardware acceleration processor may be implemented in the same silicon die as the multi-core processor for achieving gains in performance, fabrication cost reduction and energy consumption saving during operation.

  • Patent number: 11431665
    Abstract: The techniques disclosed herein provide dynamic permissions for controlling messages directed to a presenter of a communication system. For example, during a presentation of an online meeting, a system may selectively permit private messages to be sent to a presenter from designated participants. The private messages sent from the designated participants are displayed to the presenter in a manner that does not allow the other participants to see the messages. For instance, if the presenter is sharing a screen from a computer, the system can determine a set of permitted users allowed to send messages to the presenter. The system configures permissions to cause the messages to be displayed in a manner that allows the presenter to view the messages along with their presentation content, while restricting or suppressing the display of the messages to other non-permitted users. The system restricts the non-permitted users from sending messages to the presenter.

  • Patent number: 11281750
    Abstract: Techniques are disclosed for systems and methods to conduct transactions using a Multi-mode Card. A Multi-mode Card may include various components of a Smart Card and be configured to interface directly with a personal electronic device (e.g., a smart phone, a tablet computer, a personal computer, and/or other personal electronic devices) to confirm presence of the Multi-mode Card in an unattended digital transaction, such as for e-commerce and Internet purchases. A transaction system may include a logic device and an interface embedded in or on the Card, a client device such as a personal electronic device, and a server configured to provide a sales interface to a user through the client device. The logic device in the Card may be configured to authorize, encrypt, and/or otherwise facilitate a transaction involving a sale and/or other type of communication between the client device and the server.

  • Patent number: 11256622
    Abstract: In one embodiment, a processor includes a write combining buffer that includes a memory having a plurality of entries. The entries may be allocated to committed store operations transmitted by a load/store unit in the processor, and subsequent committed store operations may merge data with previous store memory operations in the buffer if the subsequent committed store operations are to addresses that match addresses of the previous committed store operations within a predefined granularity (e.g. the width of a cache port). The write combining buffer may be configured to retain up to N entries of committed store operations, but may also be configured to write one or more of the entries to the data cache responsive to receiving more than a threshold amount of non-merging committed store operations in the write combining buffer.

  • Patent number: 11188469
    Abstract: A block-based storage system may implement page cache write logging. Write requests for a data volume maintained at a storage node may be received at a storage node. A page cache for may be updated in accordance with the request. A log record describing the page cache update may be stored in a page cache write log maintained in a persistent storage device. Once the write request is performed in the page cache and recorded in a log record in the page cache write log, the write request may be acknowledged. Upon recovery from a system failure where data in the page cache is lost, log records in the page cache write log may be replayed to restore to the page cache a state of the page cache prior to the system failure.
