    Abstract: Methods, systems, and computer-readable media for a service for managing quantum computing resources are disclosed. A task management service receives a description of a task specified by a client. From a pool of computing resources of a provider network, the service selects a quantum computing resource for implementation of the task. The quantum computing resource comprises a plurality of quantum bits. The service causes the quantum computing resource to run a quantum algorithm associated with the task. The service receives one or more results of the quantum algorithm from the quantum computing resource.

    Abstract: A method for selecting a service endpoint from a plurality of service endpoints in a distributed system of a service provider may include storing processing data for each of the plurality of endpoints. A success rate may be calculated for each of the plurality of service endpoints and based on a number of processed requests from a plurality of received requests. An average latency may be calculated based on latency associated with each of the processed requests. A latency score may be calculated based on a minimum average latency and the average latency. A raw score may be calculated based on the latency score and the success rate. A selection weight may be calculated based on the raw score and a balancing parameter. One of the plurality of endpoints may be selected based on the selection weight.

    Abstract: Embodiments presented herein describe an I/O client that switches between generating high-resolution and low-resolution performance data in response to a defined event indicating there is a performance issue with a storage volume. In one embodiment, the I/O client uses one or more event rules that define a condition or threshold for determining whether to generate high-resolution or low-resolution performance data. In one embodiment, the I/O client transmits the performance data to a central monitoring system which can generate a chart plotting the performance data overtime. Because the I/O client may generate the high resolution performance data only when an event rule indicates there is a performance issue, the amount of performance data transmitted to the central monitoring system can be reduced.

    Abstract: Write optimization for block-based storage performing snapshot operations may be implemented. Write requests for a particular data volume may be received for which a snapshot operation is in progress. A determination may be made as to whether a data chunk of the data volume modified as part of the write request has not yet been stored to a remote snapshot data store as part of the snapshot operation. For a data chunk that is to be modified and that has not yet been stored, the data chunk may be stored in a local in-memory volume snapshot buffer. Once the data chunk is stored in the in-memory volume snapshot buffer, the write request may be performed and acknowledged as complete. The data chunk may be sent to the remote snapshot data store asynchronously with regard to the acknowledgment of the write request.

    Abstract translation: 可以实现对执行快照操作的基于块的存储的写入优化。 可能会收到针对特定数据卷的写请求正在进行快照操作。 作为快照操作的一部分，可以确定作为写请求的一部分修改的数据卷的数据块是否还没有被存储到远程快照数据存储。 对于要修改并且尚未存储的数据块，数据块可以存储在本地内存卷快照缓冲区中。 一旦数据块被存储在内存卷快照缓冲器中，写请求可以被执行并被确认为完成。 关于写请求的确认，数据块可以异步地发送到远程快照数据存储。

    Abstract: Generally described, systems and methods are provided for detecting locations of failures of network paths. The system collects information from a plurality of nodes and links in a network, aggregates the collected performance information across paths in the network, processes the aggregated performance information for detecting failures on the paths, and determines at least one location for network failures. In some aspects, processing the aggregated information may include determining the performance information on each of the nodes and links in the network. The performance information on each of the nodes and links may be determined by application and optimization of an objective function.
