Abstract: A first input is processed via a first configuration of a neural network to produce a first output. The first configuration defines attributes of the neural network, such as connections between neural elements of the neural network. If the neural network requires a context switch to process a second input, a second configuration is applied to the neural network to change the attributes, and the second input is processed via the second configuration of the neural network to produce a second output.

Abstract: An apparatus comprises a laser diode configured to generate light during a write operation. A slider comprises a near-field transducer (NFT) and an optical waveguide. The slider is configured for heat-assisted magnetic recording and to communicate the light to the NFT via the waveguide. A writer heater of the slider is configured to receive power during the write operation. A thermal sensor is situated at or near an air bearing surface of the slider. The thermal sensor is configured to produce a sensor signal in response to sensing back-heating from the medium while the NFT generates heat during a write operation. Circuitry, coupled to the thermal sensor, is configured to compare the sensor signal to a threshold and generate an output signal indicative of degradation of NFT performance in response to the sensor signal exceeding the threshold.

Abstract: A compressed format is selected for storage of a matrix based on a computation to be performed using the matrix and architecture of a storage compute device to which the matrix is stored. Data of the matrix is stored on the storage compute device according to the compressed format. The computation is performed using the data via a computation unit that resides within the storage compute device.

Abstract: A logical block address space of a storage compute device is reserved for use in executing commands from a host. First data is received at a first portion of the logical block address space, the first data causing a computation to be performed by the storage compute device. Second data is sent to the host via a second portion of the logical block address space, the second data describing a result of the computation.

Abstract: Mapping table entries that map logical block addresses to physical block addresses can be intercepted and compressed to save space. In some cases, the mapping table entries can be compressed into compression units, which can hold multiple mapping table entries. Portions of the mapping table entries can be arranged into groups, and a group can be compressed with a unique compression method. The compression method used to compress a group may be based on data characteristics of the group. When data corresponding to the mapping table entries are read or modified, the compressed data can be decompressed and provided to a requesting controller or processor. When the mapping table entry is modified, the updated mapping entry may be arranged into groups, and the groups can be compressed and stored to the compression units.

Abstract: Commands associated with one or more logical block addresses are received via a host interface of a storage device. Based on a timing and sequence of the commands, an extent of a file that contains the logical block addresses is determined, the file being stored on the storage device. The logical block addresses are managed internally as a unitary data structure based on determining an association between the logical block addresses and the file.

Abstract: A data object is received at a storage compute device in response to a request from a host. A requirement of the data object is determined based on a computation to be performed on the data object. The requirement related to at least speed and capacity of media used to store the data object. A tier is selected from the storage compute device based on speed and capacity characteristics of the selected tier corresponding to the requirement of the data object. The data object is stored in the selected tier.

Abstract: The disclosed technology provides for a solid state device that adaptively determines, responsive to receipt of a write command, whether or not to partition one or more individual logical blocks of data between multiple pages of a flash storage device. According to one implementation, the partitioning (e.g., spanning) determination is based on read frequency characteristics and the internal error correction code rate of the data.
