In computer programming, a thread pool is a software design pattern for achieving concurrency of execution in a computer program. Often also called a replicated workers or worker-crew model, a thread pool maintains multiple threads waiting for tasks to be allocated for concurrent execution by the supervising program. By maintaining a pool of threads, the model increases performance and avoids latency in execution due to frequent creation and destruction of threads for short-lived tasks. The number of available threads is tuned to the computing resources available to the program, such as a parallel task queue after completion of execution.
Generic application server and method of operation therefor
InactiveUS7051330B1Multiprogramming arrangementsMultiple digital computer combinationsApplication serverState switching
A generic application server is capable of simultaneously receiving requests, processing requested work, and returning results using multiple, conceptual thread pools. In addition, functions are programmable as state machines. While executing such a function, when a worker thread encounters a potentially blocking condition, the thread issues an asynchronous request for data, a state transition is performed, and the thread is released to do other work. After the blocking condition is relieved, another worker thread is scheduled to advance to the next function state and continue the function. Multiple priority work queues are used to facilitate completion of functions already in progress. In addition, lower-priority complex logic threads can be invoked to process computationally intense logic that may be necessitated by a request. Throttling functions are also implemented, which control the quantity of work accepted into the server and server response time.

Synchronous task scheduler for corba gateway
InactiveUS6839748B1Protect resourcesImprove performanceMultiple digital computer combinationsData switching networksManaged objectApplication software
A system and method for a synchronous task scheduler. The synchronous task scheduler may be used with a CORBA Gateway between CORBA-based client manager applications and an enterprise manager. The CORBA Gateway may include components such as an Event Gateway which manages events from managed objects, and a Request Gateway which manages requests and responses of managed objects. The Event Gateway and the Request Gateway may be designed as multi-threaded systems. A thread pool may be used to increase efficiency and performance of the CORBA Gateway. To ensure ordered delivery of events or replies to the CORBA gateway clients in a multi-threaded environment using a thread pool, a synchronous task scheduler may be used. There may be a synchronous task scheduler associated with each client manager to preserve the chronology of messages sent to each. The synchronous task scheduler may maintain an internal message list, and deliver one message at a time from that internal list. The synchronous task scheduler may hold a reference to a thread pool and use that thread pool to deliver messages. When a message is scheduled, the synchronous task scheduler may check if any message is already being delivered. If no prior message is currently being delivered, an available thread may be assigned from the thread pool for delivery of the message and the scheduler may initiate delivery of the message. If a prior message is being delivered, it may enqueue the message in the message list. Then, when the prior message delivery is completed, the scheduler may dequeue the message, assign another thread from the thread pool, and initiate delivery of the message. This may continue until the message list is empty.

Processing techniques for servers handling client/server traffic and communications
InactiveUS7437725B1Improve performanceMultiprogramming arrangementsMultiple digital computer combinationsRelevant informationOperational system
The present invention relates to a system for handling client / server traffic and communications pertaining to the delivery of hypertext information to a client. The system includes a central server which processes a request for a web page from a client. The central server is in communication with a number of processing / storage entities, such as an annotation means, a cache, and a number of servers which provide identification information. The system operates by receiving a request for a web page from a client. The cache is then examined to determine whether information for the requested web page is available. If such information is available, it is forwarded promptly to the client for display. Otherwise, the central server retrieves the relevant information for the requested web page from the pertinent server. The relevant information is then processed by the annotation means to generate additional relevant computer information that can be incorporated to create an annotated version of the requested web page which includes additional displayable hypertext information. The central server then relays the additional relevant computer information to the client so as to allow the annotated version of the requested web page to be displayed. In addition, the central server can update the cache with information from the annotated version. The central server can also interact with different servers to collect and maintain statistical usage information. In handling its communications with various processing / storage entities, the operating system running behind the central server utilizes a pool of persistent threads and an independent task queue to improve the efficiency of the central server. The pool of threads are continually maintained and monitored by the operating system. Whenever a thread is available, the operating system identifies the next executable task in the task queue and assigns the available thread to such task so as to allow it to be executed. Upon conclusion of the task execution, the assigned thread is released back into the thread pool. An additional I / O queue for specifically handling input / output tasks can also be used to further improve the efficiency of the central server.
