  • Publication number: 20240094905
    Abstract: Systems and methods for tier management in memory-tiering environments. In some embodiments, a method includes accessing, by a first process, a first page of the first process in a first tier of a non-uniform memory access memory; and locking, by a first thread, the first page against demotion. The first thread may be a tier-management thread of the first process, and the locking of the first page may be based on a service level of the first process.

  • Publication number: 20240020307
    Abstract: A method includes receiving, at a hardware circuit of a device, a target value corresponding to a target data. The method further includes outputting, from the hardware circuit, a first indicator that source data corresponds to the target value. The method further includes, based on the first indicator, outputting, from software executing at the device, a result indicator that the source data corresponds to the target data.

  • Patent number: 11791838
    Abstract: An accelerator is disclosed. The accelerator may include a memory that may store a dictionary table. An address generator may be configured to generate an address in the dictionary table based on an encoded value, which may have an encoded width. An output filter may be configured to filter a decoded value from the dictionary table based on the encoded value, the encoded width, and a decoded width of the decoded data. The accelerator may be configured to support at least two different encoded widths.

  • Patent number: 11567971
    Abstract: A method of processing data in a system having a host and a storage node may include performing a shuffle operation on data stored at the storage node, wherein the shuffle operation may include performing a shuffle write operation, and performing a shuffle read operation, wherein at least a portion of the shuffle operation is performed by an accelerator at the storage node. A method for partitioning data may include sampling, at a device, data from one or more partitions based on a number of samples, transferring the sampled data from the device to a host, determining, at the host, one or more splitters based on the sampled data, communicating the one or more splitters from the host to the device, and partitioning, at the device, data for the one or more partitions based on the one or more splitters.

  • Patent number: 11443142
    Abstract: A programmable data storage device configured to process images via an embedded processor is disclosed. The processor identifies luminance and chrominance data of a received image, and retrieves a first machine learning model stored in the storage device. The first model is applied for making a first prediction about the image based on luminance data, and a first determination is made in regards to a criterion. In response to making the first determination, a first label associated with the first prediction is returned. A second determination is also made in regards to the criterion. In response to making the second determination, a second machine learning model stored in the storage device is retrieved. The second machine learning model is applied for making a second prediction about the image based on the color data associated with the image, and a second label associated with the second prediction is determined.
