Task Control

The standard method of synchronous tasks is an environment without control. There is no control over the number of tasks started, the priority of request processing and the clearing, reallocating and purging of stalled requests.

Unordered

Tymeac is the solution.

  • Tymeac analyzes four thresholds providing almost unlimited control for the new task algorithm. [ example ]
  • Prioritized queues provide the means to properly schedule requests and to assure users that the "hot" request gets immediate attention. [ example ]
  • Optional timing of requests provides immediate notification of an abnormal event. [ example ]
  • Optional asynchronous processing provides for the "background" processing necessary in Enterprise environments. [ example ]
  • Automatic back out provides for intermediate component failure. [ example ]
  • A Monitor task thoroughly examines the system at set intervals reallocating and freeing resources, and, notifying the user’s early warning system of potential problems.

Orderly

Reduced Processor Overhead

With Tymeac, you pre-define your asynchronous processing environment (queues and tasks) then activate it with a call. The environment remains active only as long as necessary. Tymeac creates tasks only when necessary and destroys those tasks according to user requirements. This reduces the overall storage footprint and diminishes the machine cycles necessary to manage tasks. [ example ]

Tymeac stacks requests for processing in Wait Lists when no task is immediately available to process them.  When asynchronous tasks finish processing a request, they look in the Wait Lists for the next request. This reduces machine overhead by controlling the number of competing tasks and letting each task process multiple requests between a start/stop sequence. [ example ]

Wait Lists

Scalability

How many tasks does a logical process need?  The answer depends on the number of outstanding requests (load). The higher the load, the more tasks may be needed to process requests.

Tymeac provides four thresholds to give designers control over this parameter. Tymeac only creates a new task when a threshold is met and destroys the task after an idle period -- a dynamic response to an ever changing environment. [ example ]

Thresholds

Facilitated Recursion Processing

Asynchronous processes are a means to isolate functions.

However, when the asynchronous process itself requires another asynchronous process, the effort required in keeping track of allocated storage, time-out, back out, etc., means that designers usually chose some other, less efficient method.

Tymeac is the solution to the nested processing problem. The Tymeac management facility makes nested processing another option available to the system designer. [ example ]

Recursion

[Not familiar with recursion?  See an example.]

 

Simplified Application Development

The most successful computer programs are those that follow the Bauhaus principle; they are simple and tailored to specific, well defined tasks.

Tymeac supports the construction of simple, single process objects. These objects run under the control of Tymeac. The object gets the input message from Tymeac, executes the process, and returns the output message back to Tymeac.

The design, construction, and testing of objects in a vacuum simplifies the entire process. Since Tymeac allows objects to execute as separate tasks, the vacuum development environment reflects the real world environment.

Failure Containment

Asynchronous queue processing is a method of planning for a sequence of events (the flux of events and processes.)  The failure of one or more of those processes is part of the plan.

Tymeac provides the means to isolate the failure.

The executing task in each associated queue of the request may issue roll backs or even terminate without affecting the requesting Client.  Each queue is in isolation, and has no affect on other queues or tasks.

Event planning may take on a binary design. Did the process complete as planned, yes or no. There is no need to handle every possibility in relation to every other possibility. Asynchronous queues and tasks handle their own environment.

Simple, straightforward and fault tolerant. [ example ]

Failure Containment

 

The Web Service Solution

A major problem with Web Services is that the application proxy of the Service represents an asynchronous process, (back-end, object.)

The client passes a request to the application and receives a reply. However, all the problems of any asynchronous process are applicable.

In addition, to be truly effective and to support load balancing, the application should support Queuing and separate multi-tasking within each Queue. However, this introduces a completely new set of problems:

  • The queues must be dynamically changeable.
  • There must be a "task limit" to prevent task overload.
  • Tasks must be managed to detect and recover from stalls.
  • There must be a standard way to monitor the entire environment, to notify administrators of problems, to gather statistics for tuning and to view (GUI) the real-time system.

When one uses asynchronous processes, one must also have an asynchronous process manager.

Tymeac is that asynchronous process manager.


An asynchronous process must be able to handle:

  • The autonomous request with callback.
  • Recursion processing (when a request needs a new process itself.)
  • Intermediate back-out when encountering scheduling problems.
  • Status requests for the current and prior requests.
  • Congestion reports.
  • The ability to change parameters.
  • Deactivation during inactive periods.

 

Reduced Response Times

Today’s software does not need construction by gurus to take advantage of today’s computer.

The requirement is for modularized, functionally isolated code so that the hardware can function as designed.

Tymeac breaks up the request into concurrently active queues and tasks enabling parallel processing to significantly reduce the response time. [ example ]

Multi tasking

 

Gateway to Distributed Computing

Tymeac separates complex requests into component processes. Each component process executes as a separate logical process. The communication and database interface dependencies normally found in large, multi-function processes do not exist.

Not only are the asynchronous tasks able to execute concurrently, the component applications may interface with any network, legacy application, message queuing facility, or database protocol without restraint to each other or the requester. [ example ]

Distributed Processing

 

Ability to Multi-Process

Today’s machines are infinitely more complex than yesterday's and require an inversely proportional base of knowledge for application development with Tymeac.

Tymeac lets the operating system, CICS, and access methods schedule, monitor and control the use of resources by separating complex requests into component tasks.

The application developer codes the method without concern for the execution environment.
