摘要： Systems and methods are described for management of garbage collection processes in an on-demand code execution system. An on-demand code execution system may execute user-submitted code on virtual machine instances. As each virtual machine instance executes code, garbage (e.g., memory that is allocated and then not properly de-allocated) may accumulate and may reduce the computing resources that the virtual machine instance makes available for allocation to further code executions. A garbage collection schedule manager may be used to generate a system-wide garbage collection schedule and manage garbage collection processes in accordance with the schedule. The garbage collection schedule manager may schedule garbage collection processes at times when demand for computing resources is forecasted to be low, and may coordinate scheduling of garbage collection processes across multiple virtual machine instances and host computing devices to prevent garbage collection processes from impacting code execution performance.

摘要： A data storage manager may manage storage locations for blocks of a storage volume. The blocks of the storage volume may be assigned to a logical volume exposed to a computing instance supported by a host. Furthermore, the data storage manager may also generate and maintain a set of rules that specify the locations of blocks of the storage volume, and provides the set of rules to the host. The set of rules may be included in a data structure enabling the host to access the blocks based at least in part on the information included in the set of rules.

摘要： A data storage system includes multiple data storage units and a zonal control plane. The zonal control plane assigns volumes to respective ones of the data storage units. The data storage units include multiple head nodes and data storage sleds. At least one of the head nodes implements a local control plane for the data storage unit. Also, the head nodes of each data storage unit are configured to service read and write requests directed to one or more volumes serviced by the data storage unit independent of the zonal control plane.

摘要： Techniques for performing shared queue management utilizing shuffle sharding are described. For an event, one shared queue can be selected by first identifying a shard of a pool of queues, selecting two or more queues from the shard, and selecting the one queue that has a minimum queue load from those queues in the selected two or more queues. The selection significantly reduces or eliminates negative impacts upon a user or user function from activity of other users that utilize the shared queues.

摘要： Methods, systems, and computer-readable media for program code allocation based on processor features are disclosed. Analysis of program code is performed using static analysis and/or runtime analysis. The analysis determines one or more processor features invoked by the program code. One or more program execution servers are selected from a plurality of program execution servers based at least in part on the one or more processor features invoked by the program code. One or more selected program execution servers comprise the one or more processor features invoked by the program code, and an additional one or more of the program execution servers lack the one or more processor features invoked by the program code. The program code is executed using the one or more selected program execution servers.

摘要： Computing resource service providers operate various services used to provide functionality to customers and other computing resources operated by various entities. These services may use consistent hash rings to direct a request to a particular worker. Previous versions of the consistent hash ring may be maintained such that predecessor information can be determined. When a request is received the request and predecessor information may be provided to a worker manager. The worker manager may utilize the predecessor information to obtain state information from a predecessor worker manager. The state information may then be used to process the request.

摘要： Systems and methods are described for providing performance-based hardware emulation in an on-demand network code execution system. A user may generate a task on the system by submitting code. The system may determine, based on the code or its execution, that the code executes more efficiently if certain functionality is available, such as an extension to a processor's instruction set. The system may further determine that it can provide the needed functionality using various computing resources, which may include physical hardware, emulated hardware (e.g., a virtual machine), or combinations thereof. The system may then determine and provide a set of computing resources to use when executing the user-submitted code, which may be based on factors such as availability, cost, estimated performance, desired performance, or other criteria. The system may also migrate code from one set of computing resources to another, and may analyze demand and project future computing resource needs.

摘要： An on-demand code execution environment present in points of presence (POPs) and in regions serviced by the POPs is provided herein. For example, a POP may receive a request to execute a task associated with user-defined code. If the POP determines that the computing resources necessary to execute a received task are not available or that the POP should not execute the received task for another reason (e.g., the task is not commonly received and the computing resources needed to execute the task are therefore best allocated for other requests), the POP can forward the task to a region that the POP services for execution by an on-demand code execution environment present in the region. The on-demand code execution environment present in the region can execute the task and forward the results of the execution to the POP for distribution back to a user device that requested the task execution.

摘要： Methods, systems, and computer-readable media for cloud-based access to quantum computing resources are disclosed. A classical computing instance is launched based at least in part on a request. The computing instance is launched by a control plane of a provider network. A quantum computing resource is accessible to the computing instance and is selected based at least in part on input from a user associated with the request. The quantum computing resource is implemented in the provider network and comprises a plurality of quantum bits. A quantum algorithm is run on the quantum computing resource.

摘要： Systems and methods are described for providing auxiliary functions in an on-demand code execution system in a manner that enables efficient execution of code. A user may generate a task on the system by submitting code. The system may determine the auxiliary functions that the submitted code may require when executed on the system, and may provide these auxiliary functions by provisioning sidecar virtual machine instances that work in conjunction with the virtual machine instance executing the submitted code. The sidecars may provide auxiliary functions on a per-task, per-user, or per-request basis, and the lifecycles of the sidecars may be determined based on the lifecycles of the virtual machine instances that execute submitted code. Auxiliary functions may thus be provided only when needed, and may be provided securely by preventing a user from accessing the sidecars of other users.
