  • Patent number: 11372123
    Abstract: Provided is a method for determining convergence in full wavefield inversion (FWI) of 4D seismic (time-lapse seismic: 3D seismic surveys acquired at different times with the first survey termed as the baseline and subsequent surveys termed as monitors). FWI applied to field seismic data includes iteratively solving for subsurface property models and model difference between monitor and baseline. Iteration occurs until the model difference is sufficiently converged. Rather than determining convergence by examining an entire subsurface region of the models and/or the model difference, subparts of the subsurface region models and/or the model difference are examined in order to determine convergence. For example, different regions behave differently, include the target reservoir region (where hydrocarbon is present) and the background region that is outside the target reservoir region.

    Abstract: An apparatus in one embodiment includes at least one processing device comprising a processor coupled to a memory, with the at least one processing device being configured to maintain a replication journal for recording replication write requests in a storage system, to detect a failure impacting the replication journal, and to initiate recovery of the replication journal responsive to the detected failure. In conjunction with the recovery of the replication journal, the at least one processing device is further configured to maintain a lock contention table that characterizes lock contentions between address lock ranges required for the recovery of the replication journal and address lock ranges required by other write requests in the storage system, and to utilize the lock contention table to resolve one or more potential deadlocks that would otherwise prevent completion of the recovery of the replication journal. Other embodiments include methods and computer program products.

  • Publication number: 20220197567
    Abstract: Dynamic storage provisioning for nested clusters is disclosed. A hosted cluster (HC) storage provisioner, executing in a hosted cluster that is hosted by an infrastructure cluster (IC), receives a request to dynamically provision a hosted cluster (HC) persistent volume object that is coupled to a physical storage. The HC storage provisioner causes an IC control plane executing on the IC to generate IC volume metadata that is backed by a storage volume on the physical storage. The HC storage provisioner determines that the IC volume metadata has been generated. The HC storage provisioner creates HC volume metadata on the hosted cluster that is linked to the IC volume metadata, the HC volume metadata comprising an HC persistent volume object that represents a persistent volume for use by the hosted cluster that is backed, via the IC volume metadata, by the physical storage.

  • Publication number: 20220182981
    Abstract: A station (STA) may operate as a first peer-to-peer (P2P) client (P2P1) for P2P operations with dual-stage triggering. The STA may decode a primary frame trigger frame (TF) from an access point (AP) operating as a coordinator. The primary TF may allocate resources in an initial portion of a time-duration allocation to the P2P1 for the P2P operations with one or more other peer stations, including a second P2P client (P2P2) and a third P2P client (P2P3). The primary TF may further allocate resources in a subsequent portion of the time-duration allocation to the P2P2 for the P2P operations. The STA may also encode a first secondary TF for transmission within the initial portion of the time-duration allocation. The first secondary TF may allocate specific resource units (RUs) to the one or more other peer stations. The STA may also decode a TB physical layer protocol data unit (TB PPDU) encoded in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format.
