In some examples, a system stores, in a first database having a first schema, metrics received from a network comprising communication nodes, the metrics relating to operations of the communication nodes, and the first database associating the metrics with metadata corresponding to hierarchical components in a topology of the network. In response to an alert relating to an issue in the network, the system computes a health measure based on the metrics, the health measure indicating a health status of a first component, performs a dynamic runtime mapping of the metadata associated with the metrics in the first database having the first schema with corresponding metadata in a second database having a second schema different from the first schema, where the second database contains information of a topology of the network, and initiates a management action to address the health status based on the health measure and the dynamic runtime mapping.

Health-based management of a network

A network interface controller (NIC) capable of efficient operation management for host accelerators is provided. The NIC can be equipped with a host interface and triggering logic block. During operation, the host interface can couple the NIC to a host device. The triggering logic block can obtain, via the host interface from the host device, an operation associated with an accelerator of the host device. The triggering logic block can determine whether a triggering condition has been satisfied for the operation based on an indicator received from the accelerator. If the triggering condition has been satisfied, the triggering logic block can obtain a piece of data generated from the accelerator from a memory location and execute the operation using the piece of data.

System and method for facilitating operation management in a network interface controller (NIC) for accelerators

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.

Resiliency to memory failures in computer systems

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.
