Abstract: Systems for managing a distributed computing system. A method embodiment commences upon receiving user-provided specification parameters that describe a target state of a computing entity. After generating a set of resource management commands to achieve the specified target state of a computing entity, the resource management commands are scheduled for execution. As execution of the resource management commands is being carried out, the execution status of the resource management commands is continuously monitored. If performance of the resource management commands raises an error and/or the resource entity state is different than predicted, a set of remediation actions are determined, and an additional set of processing operations are invoked to accomplish the remediation actions. When all resource management commands and/or any remediation actions have completed successfully, the target resource entity state has been achieved.

Abstract: Optimizations are provided for remotely debugging a node in the cloud. Initially, a SMM environment is initialized in a computer's BIOS. Then, a debug agent that is located within the SMM environment receives an instruction indicative of a chipset-specific or platform-specific health-related issue. Based on this instruction, the debug agent executes a script entry by fetching health-related information from the computer's addressable endpoints. This information includes health-related metadata and/or counter information. The debug agent then records the information. Furthermore, the debug agent obtains a resolution for the health-related issue. Here, this resolution is at least partially based on the recorded information.

Abstract: Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.
