Abstract: The present disclosure relates to a home automation system that is automated based on user preferences provided by a social networking system, where the home automation system provides a short-range, high-speed wireless connection that is contained within the safe boundaries of a home. Briefly described, the home automation system employs one or more home automation devices to control various home devices within the home based on detection of one or more users' social profile, where each home automation device is configured to broadcast and communicate via a short-range, multi-gigabit-per-second (MGbps) wireless communication link that can be utilized by the various home devices. Furthermore, each home automation device is configured to be self-tuning, thereby enabling automatic efficient management of the MGbps wireless communication link.

Abstract: Various embodiments (“systems”) are described for transferring data from a primary storage (e.g., magnetic disk drives, solid state drives, etc.) to an optical cold storage rack. The optical cold storage rack may include many physical optical storage disks, but a much smaller number of burners and readers (e.g., optical disk drives). When data is to be transferred to the optical cold storage rack, the system may generate a plan for performing the transfer. “Migration worker” components may then implement the plan and may be exclusively dedicated to implementing such plans. In various embodiments, the plan may specify how large data file “aggregates” (collections of portions of one or more data files) are to be distributed across optical disks (“disks”) to improve throughput during subsequent reading operations from the optical cold storage rack. The plan may also anticipate the relation between the limited number of burners/readers and the overall optical cold storage rack disk capacity.

Abstract: Some embodiments includes an interrupt-driven data transport architecture utilizing a memory channel bus. For example, a first logic component at a first computing device can initiate a data access request involving a second logic component at a second computing device. The first logic component can store request information associated with the data access request in a predefined memory space of a memory module connected via a memory channel bus to the first logic component and the second logic component. The first logic component can then generate a request-ready interrupt signal through one or more redundant pins of the memory channel bus. The second logic component can be triggered by the interrupt signal to read the request information from the predefined memory space. The second logic component can use that information to complete the request.

Abstract: Channel performance can be improved in a storage device, such as a flash memory or a flash-based solid state drive, by dynamically provisioning available data channels for both write and read operations. In one aspect, a set of available data channels on a storage device is partitioned into a set of write channels and a set of read channels according to a read-to-write ratio. Next, when an incoming data stream of mixed read requests and write requests arrives at the storage device, the allocated read channels process the read requests on a first group of memory blocks, which does not include garbage collection and write amplification on the first group of memory blocks. In parallel, the allocated write channels process the write requests on a second group of memory blocks, which does include garbage collection and write amplification on the second group of memory blocks.

Abstract: Techniques, systems, and devices are disclosed for reducing data read/write overhead in a storage array, such as a redundant array of independent disks (RAID), by dynamically configuring stripe sizes in disk drives. In one aspect, each disk drive is configured with multiple stripe sizes based on statistical file sizes of incoming data traffic. For example, a preconfigured disk drive can include a set of different stripe sizes wherein a stripe size is consistent with the size of a common file type in the historical or predicted data traffic. Moreover, the allocation of disk space for each stripe size may be consistent with the composition percentage of the associated file type in the historical or predicted data traffic. As a result, reads/writes of large data files in the storage array predominantly take place on a single disk drive rather than on multiple drives, thereby reducing read/write overheads.

Abstract: Embodiments are disclosed for managing a distributed data center. The managing can include receiving content interaction history associated with a first social networking account of a social networking system at a content distribution system; maintaining a cache map of available cache appliances to implement a distributed cache store; selecting a content item to push to a residential cache appliance based on the content interaction history, wherein pushing the content item includes updating the cache map to associate a network address of the residential cache appliance with an identifier of the content item; and providing a content distribution service configured to redirect a content streaming request for the content item to the residential cache appliance when the content item is determined to be available in the distributed cache store according to the cache map.

Abstract: Some embodiments of this disclosure operate a network device in conjunction with a social networking system. The operations can include establishing a network island by providing network connectivity in a local region via the network device; connecting the network device to an intermittent network channel that is not continuously active; when the intermittent network channel is active, receiving a content item via the intermittent network channel, wherein the content items is not destined for a specific device in the network island; and caching the content item in a cache storage of the network device such that the content item is available to be accessed by any computing device within the network island.

Abstract: The disclosure is directed to storing data in different tiers of a database based on the access pattern of the data. Immutable data, e.g., data that does not change or changes less often than a specified threshold, is stored in a first storage tier of the database, and mutable data, e.g., data that changes more often than immutable data, is stored in a second storage tier of the database. The second storage tier of the database is more performant than the first storage tier, e.g., the second storage tier has a higher write endurance and a lower write latency than the first storage tier. All writes to the database are performed at the second storage tier and reads on both storage tiers. The storage tiers are synchronized, e.g., the set of data is copied from the second to the first storage tier based on a trigger, e.g., a specified schedule.

Abstract: Technology is provided for partitioning a shared unified cache in a multi-processor computer system. The technology can receive a request to allocate a portion of a shared unified cache memory for storing only executable instructions, partition the cache memory into multiple partitions, and allocate one of the partitions for storing only executable instructions. The technology can further determine the size of the portion of the cache memory to be allocated for storing only executable instructions as a function of the size of the multi-processor's L1 instruction cache and the number of cores in the multi-processor.

Abstract: The present invention relates to a new low-power, high performance multiplier circuit design, and more specifically to a partitioned multiplier implemented using a modified, symmetrical Wallace tree structure that enables the power to parts of the multiplier to be selectively turned on and off. A multiplier implemented using complementary pass-transistor logic (CPL) 3:2 carry save adders (CSAs) includes a left array with a first multiple of CPL CSAs, a right array with a second multiple of CPL CSAs, and a merge block coupled to the left array and the right array, such that the left and right arrays are not coupled to each other. The left and right arrays are configured to independently receive power, such that, each array can be turned on and off without affecting the other array. The merge block includes a third multiple of CPL CSAs and the merge block can be configured to output a result value of a multiplication operation.
