摘要： A resiliency system detects and corrects memory errors reported by a memory system of a computing system using previously stored error correction information. When a program stores data into a memory location, the resiliency system executing on the computing system generates and stores error correction information. When the program then executes a load instruction to retrieve the data from the memory location, the load instruction completes normally if there is no memory error. If, however, there is a memory error, the computing system passes control to the resiliency system (e.g., via a trap) to handle the memory error. The resiliency system retrieves the error correction information for the memory location and re-creates the data of the memory location. The resiliency system stores the data as if the load instruction had completed normally and passes control to the next instruction of the program.

摘要： A method and system for detecting congestion in a network of nodes, abating the network congestion, and identifying the cause of the network congestion is provided. A congestion detection system may comprise a detection system, an abatement system, and a causation system. The detection system monitors the performance of network components such as the network interface controllers and tiles of routers to determine whether the network is congested such that a delay in delivering packets becomes unacceptable. Upon detecting that the network is congested, an abatement system abates the congestion by limiting the rate at which packets are injected into the network from the nodes. Upon detecting that the network is congested, a causation system may identify the job that is executing on a node that is the cause of the network congestion.

摘要： A system for debugging targets using various techniques, some of which are particularly useful in a multithread environment. These techniques include implementing breakpoints using out-of-line instruction emulation so that an instruction replaced with a breakpoint instruction does not need to be returned to its original location for single-step execution, executing a debugger nub for each target as part of the target task but using a nub task thread for the nub execution that is separate from the target task threads, providing immunity from breakpoints for specified threads such as the nub thread via specialized breakpoint handlers used by those threads, and virtualizing the debugger nub such that a shared root nub provides a uniform interface between the debugger and the target while specialized nubs provide differing functionality based on the type of target being debugged.

摘要： A method and system in a multithreaded processor for processing events without interrupt notifications. In one aspect of the present invention, an operating system creates a thread to execute on a stream of the processor. During execution of the thread, the thread executes a loop that determines whether an event has occurred and, in response to determining whether an event has occurred, assigns a different thread to process the event so that multiple events can be processed in parallel and so that interrupts are not needed to signal that the event has occurred. Another aspect of the present invention provides a method and system for processing asynchronously occurring events without interrupt notifications. To achieve this processing, a first thread is executed to generate a notification that the event has occurred upon receipt of the asynchronously occurring event. A second thread is also executed that loops determining whether a notification has been generated and, in response to determining that a notification has been generated, performing the processing necessary for the event.
