Systems and methods for scheduling tasks

A task scheduler for scheduling tasks, the task scheduler operating on a processing node of a plurality of processing nodes, each processing node of the plurality of processing nodes including a distinct task scheduler, the task scheduler configured to:

• retrieve a task descriptor from a local memory, the task descriptor corresponding to a task scheduled for execution at a current time and comprising at least a task execution time, a frequency for performing the task, and a task identifier;
• determine a number of active processing nodes of the plurality of processing nodes, each processing node of the plurality of processing nodes associated with the distinct task scheduler;
• determine a range of allocation identifiers assigned to the processing node based at least in part on the number of active processing nodes;
• convert the task identifier into an allocation identifier;
• determine whether the allocation identifier is within the range of allocation identifiers assigned to the processing node;
• in response to determining that the allocation identifier is within the range of allocation identifiers assigned to the processing node:
• execute the task;
• update the task execution time based on the frequency for performing the task;
• and
• re-queue the task descriptor in the local memory;
• determine whether the number of active processing nodes has changed;
• and
• in response to determining the number of active processing nodes has changed, recalculate the range of allocation identifiers assigned to the processing node based at least in part on the number of active processing nodes.
