Dynamic updating software systems based aspects go dating serious relationship
In the case of such long-running programs, the initial requirements could change after the program has started executing.To shorten the time it takes to arrive to a result when running a distributed computationally-intensive application, this paper proposes leveraging the power and flexibility of dynamic software updates.This dissertation establishes the value of and recommends practices for applying dynamic soft-ware updates to computationally-intensive applications—a computing domain characterized by long-running computations, expensive computing resources, and a tedious deployment process.This dissertation argues that updating computationally-intensive applications dy-namically can reduce their time-to-discovery metrics—the total time it takes from posing a problem to arriving at a solution—and, as such, should become an intrinsic part of their software lifecycle.We validate our approach via a case study of dynamically changing a parallel scientific simulation.

Programs written in managed languages are compiled to a platform-independent intermediate representation, such as Java bytecode.
We demonstrate the applicability of our approach by making a source code editor and a symbolic debugger enhancements-aware. describe generalized structural program differences. Program differencing is an active research area and several new differencing algorithms have been proposed recently.
