Steering programs via time travel

چکیده
Despite years of research into human computer interaction (HCI), the environments programmers must use for problem-solving today—with separate modes and tools for writing, compiling, testing, visualizing, and debugging— derive their basic structure from historical accident, and take little advantage of HCI research into the cognitive issues of programming. Neglecting these issues is an impediment to the programmers’ ability to produce reliable, maintainable software. In this paper, we describe a system in which programmers can modelessly steer as they specify, visualize, explore, and alter the behavior of a program while traveling through the program’s logical time. This approach supports two often-neglected cognitive principles that programmers need for problemsolving.

Falcon { Toward Interactive Parallel Programs :
This paper focuses on the opportunities and costs of on-line steering as applied to a substantial parallel application. We demonstrate potential performance improvements through the use of the Falcon system, an experimental system for the on-line monitoring and steering of parallel programs. The visual presentation of program output along with animated displays of program performance informatio...
متن کاملProgram Steering: Improving Adaptability and Mode Selection via Dynamic Analysis
A multi-mode software system contains several distinct modes of operation and a controller for deciding when to switch between modes. Even when developers rigorously test a multi-mode system before deployment, they cannot foresee and test for every possible usage scenario. As a result, unexpected situations in which the program fails or underperforms (for example, by choosing a non-optimal mode...
متن کاملDirectional control-response compatibility of joystick steered shuttle cars.
UNLABELLED Shuttle cars are an unusual class of vehicle operated in underground coal mines, sometimes in close proximity to pedestrians and steering errors may have very serious consequences. A directional control-response incompatibility has previously been described in shuttle cars which are controlled using a steering wheel oriented perpendicular to the direction of travel. Some other shuttl...
متن کاملRetrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...
متن کاملA Novel Method for Travel System Patterns
Due to population growth in urban areas, especially in the capital cities in developing countries, the use of private vehicles are increasing, leading to many problems such as congestion, pollution, noise, long travel time, high travel cost and more side effects. In such circumstances government policy would encourage people to use public transportation. In the meantime, employing the Intellige...
