Abstract: The present technology addresses a need in the art for a closed-loop automation system of a managed network that detects and fixes an issue in the managed network with minimal to no human intervention. The closed-loop automation system employs a domain-independent semantic machine reasoning engine as an underlying engine. After detecting the issue in the managed network, the system searches through a knowledge base to find a match for the detected issue. The knowledge base includes previously collected knowledge from subject matter experts and maintenance teams. The system then proposes a remedial action to a user of the managed network for approval. After approval by the user, the system implements the remedial action.

Abstract: An evaporative cooling device including a combination of insulative surfaces and evaporative surfaces that may hold and cool contents with walls that are made of semipermeable materials. The evaporative surfaces store and facilitate the evaporation of a liquid to cool the interior of the evaporative cooling device while the insulative surfaces limit heat transfer in or out of the evaporative cooling device from air, sunlight or the ground. The evaporative cooling device is further capable of holding a variety of products at a temperature below ambient environmental temperature, assuming less than 100% humidity. Moreover, the evaporative cooling device may be designed to be lightweight and collapsible for easy transport and storage.

Abstract: Aspects disclosed herein include avoiding deadlocks in processor-based systems employing retry and in-order-response non-retry bus coherency protocols. In this regard, an interface bridge circuit is communicatively coupled to a first core device that implements a retry bus coherency protocol, and a second core device that implements an in-order-response non-retry bus coherency protocol. The interface bridge circuit receives a snoop command from the first core device, and forwards the snoop command to the second core device. While the snoop command is pending, the interface bridge circuit detects a potential deadlock condition between the first core device and the second core device. In response to detecting the potential deadlock condition, the interface bridge circuit is configured to send a retry response to the first core device. This enables the first core device to continue processing, thereby eliminating the potential deadlock condition.

Abstract: Maintaining cache coherency using conditional intervention among multiple master devices is disclosed. In one aspect, a conditional intervention circuit is configured to receive intervention responses from multiple snooping master devices. To select a snooping master device to provide intervention data, the conditional intervention circuit determines how many snooping master devices have a cache line granule size the same as or larger than a requesting master device. If one snooping master device has a same or larger cache line granule size, that snooping master device is selected. If more than one snooping master device has a same or larger cache line granule size, a snooping master device is selected based on an alternate criteria. The intervention responses provided by the unselected snooping master devices are canceled by the conditional intervention circuit, and intervention data from the selected snooping master device is provided to the requesting master device.

Abstract: Self-aware, peer-to-peer cache transfers between local, shared cache memories in a multi-processor system is disclosed. A shared cache memory system is provided comprising local shared cache memories accessible by an associated central processing unit (CPU) and other CPUs in a peer-to-peer manner. When a CPU desires to request a cache transfer (e.g., in response to a cache eviction), the CPU acting as a master CPU issues a cache transfer request. In response, target CPUs issue snoop responses indicating their willingness to accept the cache transfer. The target CPUs also use the snoop responses to be self-aware of the willingness of other target CPUs to accept the cache transfer. The target CPUs willing to accept the cache transfer use a predefined target CPU selection scheme to determine its acceptance of the cache transfer. This can avoid a CPU making multiple requests to find a target CPU for a cache transfer.

Abstract: Providing scalable dynamic random access memory (DRAM) cache management using tag directory caches is provided. In one aspect, a DRAM cache management circuit is provided to manage access to a DRAM cache in a high-bandwidth memory. The DRAM cache management circuit comprises a tag directory cache and a tag directory cache directory. The tag directory cache stores tags of frequently accessed cache lines in the DRAM cache, while the tag directory cache directory stores tags for the tag directory cache. The DRAM cache management circuit uses the tag directory cache and the tag directory cache directory to determine whether data associated with a memory address is cached in the DRAM cache of the high-bandwidth memory. Based on the tag directory cache and the tag directory cache directory, the DRAM cache management circuit may determine whether a memory operation can be performed using the DRAM cache and/or a system memory DRAM.
