According to one embodiment of the present invention, a system dynamically schedules performance of tasks, and comprises a computer system including at least one processor. The system determines resources required or utilized by each task for performance of that task on a target system, and compares the determined resources of the tasks to identify tasks with similar resource requirements. The identified tasks with similar resource requirements are scheduled to be successively performed on the target system. Embodiments of the present invention further include a method and computer program product for dynamically scheduling performance of tasks in substantially the same manner described above.

Dynamic test scheduling by ordering tasks for performance based on similarities between the tasks

An indication of a change to at least one source file associated with a software build is received via a processor. A set of test levels of a level-based testing suite are sequentially processed, where each test level subsequently processed includes tests with decreasing qualitative testing information relative to tests associated with previously-processed test levels. For each processed test level, at least one test is selected that tests the change to the at least one source file associated with the software build, test coverage relative to a target risk level for the software build is determined for each selected test, and test selection is terminated upon determining that the test coverage for the selected tests at least meets the target risk level for the software build.

Automated level-based targeted test configuration

The present invention discloses a method, apparatus and software for determining a relative measure of the risk of faults in a built product relative to a reference build of the product. The measure can be based on a balance between the additional risk added as a result of changes made in a given build and the risk reduction resulting from testing applied to the build. The product associated with the builds can be a software product, a firmware product, an electronic device, and/or any manufactured product.

Determining a relative measure of fault risk for a built system

Determining a relative measure of build quality for a built product based on analysis of historical test data from test cases applied to a series of builds of the built product, by identifying one or more first sets of test results, each first set of test results being derived from the application of a set of test cases to a series of builds of a built product; determining a test quality coefficient for each test case based on the respective test results from the first set of test results; identifying a second set of test results derived from the application of one or more of the test cases to a further build of the built product; applying each test quality coefficient to each corresponding test result from the second set; and calculating the mean of the second set of test results as qualified by their corresponding test quality coefficient.

An image data display system in which more than one portion of an image displayed on a screen may be transformed by extraction, scaling or rotation in relation to other areas of the screen concurrently. The image display system is of the type which is capable of receiving transformation operation orders from a control processor prior to being sent the image. As the image is received, the display system performs the transform operations prior to displaying the image data. The control processor is modified to include means to determine when two or more concurrent transforms of portions of an image will cause the portions to be displayed on common areas of the display screen (or overlap) and, means to order and transmit to the display device the list of transforms to be performed so that the image pel definition signals are transmitted to the display device where image portions occupy common areas of the display screen the pel definition signals relating to higher priority portion of the image control the final content of the common areas of the displayed image.

Image display system with transformation operation ordering

A method of determining the coincidence of a subject area and a clip area in a graphic display system, comprising creating three parts list, one for parts of the subject area that are outside the clip area, a second for parts of the clip area that are inside the subject area and a third for overlapping lines. The parts of the subject area which lie outside the clip area are defined by examining the parts lists. The output can then be used to control a pen plotter, in which different colors are used so that underlying areas do not have to be linked over with overlay colors.
