Abstract: Systems and methods are disclosed for scheduling a plurality of tasks for execution on one or more processors. An example method includes obtaining a counter value of a counter. The method also includes for each work queue of a plurality of work queues, identifying an execution period of the respective work queue and comparing a counter value to an execution period of the respective work queue. Each work queue includes a set of tasks and is defined by an execution period at which to run the respective set of queued tasks. The method further includes selecting, based on the comparing, a subset of the plurality of work queues. The method also includes scheduling a set of tasks of slower frequency queued in a selected work queue for execution on one or more processors before a set of tasks queued in a non-selected work queue. The work items may be scheduled in O(1) because the design inherently prioritizes the tasks based on the urgency of their completion, and may do so by resetting a work queue pointer.

Abstract: A system and method for of prioritizing accumulation of time-dependent data is disclosed. In an embodiment, a plurality of data elements are identified to be retrieved. The data elements include a high-priority data element and a low-priority data element. A first data retrieval operation is performed to retrieve the high-priority data element, to store a copy of the high-priority data element in a memory structure, and to reserve a memory space in the memory structure for the low-priority data element based on the low-priority data element corresponding to the high-priority data element. In parallel with the first data retrieval operation, a second data retrieval operation is performed to analyze the memory structure to detect the reserved memory space, upon detecting the reserved memory space, to retrieve the low-priority data element, and to store a copy of the low-priority data element in the reserved memory space.

Abstract: Systems and methods are disclosed for communicating state information of a session between a plurality of processing threads in a hierarchy. The session is passed down through the hierarchy, with one or more threads processing the session at each level of the hierarchy. An example method includes reading a first pointer of a first processing thread and comparing the first pointer to a second pointer of a second processing thread. The second processing thread is dependent on the first processing thread. The method also includes in response to determining that the first pointer does not match the second pointer, processing a set of configuration items in a session. The method further includes after processing the set of configuration items in the session, updating the second pointer of the second processing thread to match the first pointer of the first processing thread.

Abstract: The online method for managing scheduling of, payment for and accounting of a medical management transaction available over a global system for a patient and a health care provider, includes providing a database server, providing an application server on which the medical management system resides, providing payment processing services, exchanging regulated data with a medical services government agency, accessing electronic medical records services by the patient, including uploading existing medical records by the health care provider and the patient, commenting on accessed records by the patient to provide patient comments, storing the patient comments in the system and providing the patient comments to the health care provider along with records requested by the health care provider.
