Abstract: Many signal processing, machine learning and scientific computing applications require a large number of multiply-accumulate (MAC) operations. This type of operation is demanding in both computation and memory. Process in memory has been proposed as a new technique that computes directly on a large array of data in place, to eliminate expensive data movement overhead. To enable parallel multi-bit MAC operations, both width- and level-modulating memory word lines are applied. To improve performance and provide tolerance against process-voltage-temperature variations, a delay-locked loop is used to generate fine unit pulses for driving memory word lines and a dual-ramp Single-slope ADC is used to convert bit line outputs. The concept is prototyped in a 180 nm CMOS test chip made of four 320×64 compute-SRAMs, each supporting 128× parallel 5 b×5 b MACs with 32 5 b output ADCs and consuming 16.6 mW at 200 MHz.

Abstract: A cache management mechanism is provided having a size that is independent of an overall storage capacity of a non-volatile memory (NVM). The cache management mechanism includes a first level map data structure arranged as a first-in-first-out (FIFO) buffer to list a plurality of host access commands sequentially received from a host device. Each command has an associated host tag value. A cache memory stores user data blocks associated with the commands. A second level map of the cache management mechanism correlates cache addresses with the host tag values. A processing core searches the FIFO buffer in an effort to match a logical address of an existing command to the logical address for a new command. If a match is found, the host tag value is used to locate the cache address for the requested data. If a cache miss occurs, the new command is forwarded to the NVM.

The storage device provides a virtual memory region to the host device such that a host-dedicated memory region having a first size included in the first memory device is mapped to the virtual memory region having a second size larger than the first size.

Abstract: Systems and methods are provided for upgrading wireless network devices, such as access points (APs). When a first AP needs an upgrade, a network controller of the first AP may identify and select a neighbor AP. The radio(s) of the neighbor AP can be split into multiple logical radios, at least one of which includes a backup virtual AP (VAP). The backup VAP can support client devices originally supported by the first AP, allowing those client devices to roam to the neighbor AP while the first AP is upgrading, and without needing to re-associate with the neighbor AP. From the client device perspective, it appears as though they are still being supported by the first AP. Upon upgrading the first AP, the client devices can roam back to the first AP (without needing to re-associate with the first AP). No downtime is experienced, and no RF holes are generated.

Abstract: The embodiments herein creates DCT mechanisms that initiate a DCT at the time the updated data is being evicted from the producer cache. These DCT mechanisms are applied when the producer is replacing the updated contents in its cache because the producer has either moved on to working on a different data set (e.g., a different task) or moved on to working on a different function, or when the producer-consumer task manager (e.g., a management unit) enforces software coherency by sending Cache Maintenance Operations (CMO). One advantage of the DCT mechanism is that because the direct cache transfer takes place at the time the updated data is being evicted, by the time the consumer begins its task, the updated contents have already been placed in its own cache or another cache within the cache hierarchy.

Abstract: A storage appliance can be designed to facilitate efficient restore of multiple backed up files in a system that allows files to share data blocks. A data management application or storage OS names data blocks and communicates those names to the storage appliance when backing up to or through the storage appliance. The storage appliance can leverage the data block names when restoring a group of files by restoring at data block granularity instead of file granularity. Restoring at the granularity of the data blocks by their names allows the storage appliance to avoid repeatedly sending a same data block to the restore requestor (e.g., a storage OS or data management application) while still instructing the restore requestor how to reconstruct the corresponding file(s) with mappings between valid data ranges and the named data blocks.

The second physical layer circuit includes a disconnection detection circuit that detects device disconnection of a device connected to the second bus side. If device disconnection is detected in the second period, the connection between the first bus and the second bus is switched from off to on after a wait period has elapsed from the timing at which the device disconnection was detected.

This androgyny can enable the zone storage system to store a complete chunk at a zone based on real time use. In an aspect, an androgynous zone storage component can take on, or transition between, a de facto front-end storage device character or de facto back-end storage device character in response to deployment of the androgynous zone storage component in the storage system.

Abstract: Improved techniques for applying performance controls in a data storage system based on overload correlations between units of managed storage objects (UMOs). When a performance indicator (e.g. response time) for a target UMO is outside an acceptable range, a competing UMO that potentially shares at least one potentially shared hardware component with the target UMO is identified. An overload correlation between the target UMO and the competing UMO is generated that indicates an amount of correlation between the performance indicator for the target UMO and a performance indicator for the competing UMO. A performance control is then applied to the throughput of the competing UMO that reduces the throughput of the competing UMO. The amount that the throughput of the competing UMO is reduced is based on the amount of overload correlation between the target UMO and the competing UMO.

Abstract: Approaches for transferring control to a bit set. Execution of a bit set upon a host operating system is monitored. A determination is made that the execution of the bit set exhibits a suspicious characteristic. In response, the execution of the bit set on the host operating system is ceased. Then, the bit set is copied into an isolated environment and control to the bit set is transferred within the isolated environment. Thereafter, execution analysis upon the bit set is initiated in the isolated environment. The isolated environment may, but need not, reside on a different physical device than upon which executes the host operating system.

Abstract: Disclosed herein are methods, systems, and processes to perform hierarchical fencing in clustered environments. A first set of registration keys is received from a first set of nodes that are supported by a first hypervisor and are part of a cluster. A first key value is generated based on the first set of registration keys. The first key value is then stored on a shared storage device shared by the first set of nodes and a second set of nodes supported by a second hypervisor. Upon receiving a request to perform an input/output (I/O) fencing operation, the first key value is modified and the second key value is removed from the shared storage device.
