Abstract: A computing device automatically detects technical conditions for calls, such as voice calls, in a communication system. The technical conditions include transport type (e.g., TCP, UDP), connection type (e.g., wired, wireless local area network, mobile/cellular), packet loss, latency, and jitter. The computing device performs automatic analysis of the detected technical conditions. The automatic analysis may include comparing the detected transport type with a preferred transport type (e.g., a non-TCP transport, such as UDP), comparing the detected connection type with a preferred connection type (e.g., wired), or comparing packet loss, latency, or jitter with corresponding threshold values (e.g., maximum values or average values). The computing device automatically generates output related to one or more of the detected technical conditions based at least in part on the automatic analysis.

Abstract: Techniques are described for memory coherence in a multi-core system with a heterogeneous memory architecture comprising one or more hardware-managed caches and one or more software-managed caches. According to one embodiment, a set of one or more buffers are allocated in memory, and each respective buffer is associated with a respective metadata tag. The metadata tag may be used to store metadata that identifies a state associated with the respective buffer. The multi-core system may enforce coherence for the one or more hardware-managed caches and the one or more software-managed caches based on the metadata stored in the metadata tag for each respective buffer in the set of one or more buffers. The multi-core system may read the metadata to determine whether a particular buffer is in a hardware-managed or a software-managed cacheable state. Based on the current state of the particular buffer, the multi-core system may perform coherence operations.

Abstract: A multi-core processing system that uses computational sprinting to generate high levels of computational output for short periods of time at power consumption levels that are not sustainable over longer periods of time due to thermal and/or other constraints. This is done using a number of processing cores that, when operated simultaneously, utilize available thermal capacity within the system to consume power and produce heat that is in excess of a thermal design power (TDP) of the system, but is tolerable because of the short period of operation. The system and/or method described herein may include thermal capacitors in the form of phase change materials (PCMs), may implement normal, sprint and/or cooling modes of operation, and may employ parallel sprinting, frequency sprinting, sprint pacing and/or sprint-and-rest techniques, to cite several possibilities.

Abstract: In connection with an operations management system, a vendor feedback system reports on operational events that occur on customer data centers. The operations management system provides a standardized environment for providing feedback to a vendor of components installed at the customer data centers. Methods supported by the vendor feedback system can include directing the operations management system to report on predefined operational events involving the components installed by the vendor at the customer data centers. Event reports are then stored at the customer data centers in response to occurrences of the predefined operational events. The event reports can be generated in cooperation with the operations management system. The event reports are transmitted to the vendor as feedback relating to the components, and the vendor receives the event reports from the customer data centers.
