Abstract: Systems and methods are described for managing asynchronous code executions in an on-demand code execution system or other distributed code execution environment, in which multiple execution environments, such as virtual machine instances, can be used to enable rapid execution of user-submitted code. When asynchronous executions occur, a first execution may call a second execution, but not immediately need the second execution to complete. To efficiently allocate computing resources, this disclosure enables the second execution to be scheduled accordingly to a state of the on-demand code execution system, while still ensuring the second execution completes prior to the time required by the first execution. Scheduling of executions can, for example, enable more efficient load balancing on the on-demand code execution system.

Abstract: Systems and methods are described for managing asynchronous code executions in an on-demand code execution system or other distributed code execution environment, in which multiple execution environments, such as virtual machine instances, can be used to enable rapid execution of user-submitted code. When asynchronous executions occur, one execution may become blocked while waiting for completion of another execution. Because the on-demand code execution system contains multiple execution environments, the system can efficiently handle a blocked execution by saving a state of the execution, and removing it from its execution environment. When a blocking dependency operation completes, the system can resume the blocked execution using the state information, in the same or different execution environment.

Abstract: Guest memory data structures are read by one or more read operations which are set up to handle page faults and general protection faults generated during the read in various ways. If such a fault occurs while performing the one or more read operations, the fault is handled and the one or more read operation is terminated. The fault is handled by either dropping the fault and reporting an error instead of the fault, by dropping the fault and invoking an error handler that is set up prior to performing the read operations, or by forwarding the fault to a fault handler that is setup prior to performing the read operations. If no fault occurs, the read operations complete successfully. Thus, under normal circumstances, no fault is incurred in a read operation on guest memory data structures.

For example, maintenance is restricted until the computing system broadcasts a notification. Legacy software and devices that do not understand these notifications can be told the AC power is not present nominally, and then be notified of AC power presence during maintenance intervals.
