Adaptive, Profile-Based Compilation of Highly Interactive, Graphical Applications by Demonstration

快速原型环境提供了允许用户快速创建和修改交互式应用程序的高级操作，例如图形界面、科学和程序可视化以及模拟（即快速编程大图）。这些环境通常牺牲速度和存储来提高灵活性。研究人员提出了可以减少存储并提高性能的优化方法。然而，程序员必须手动应用这些优化，这阻碍了应用程序的快速迭代开发。这个项目的目标是开发自适应的、基于概要文件的编译技术，这些技术可以自动应用这些优化，以便程序员可以利用快速原型技术，同时仍然保持出色的时间和存储性能。约束和结构化图形是本研究的目标，因为研究表明这两种技术促进了图形用户界面的快速迭代开发。该项目正在开发以下技术：(1)分析器在操作执行时监视操作，并提取有关约束评估和变量访问的信息；(2)自适应编译器使用这些信息动态实现各种性能和存储优化。＊＊＊

Rapid prototyping environments provide high-level operations that allow users rapidly to create and modify interactive applications, such as graphical interfaces, scientific and program visualizations, and simulations (i.e., quickly program the Obig pictureO). These environments often sacrifice speed and storage for increased flexibility. Researchers have proposed optimizations that can reduce storage and improve performance. However, the programmer must manually apply these optimizations, which impedes rapid, iterative development of applications. The objective of this project is to develop adaptive, profile-based compilation techniques that automatically apply these optimizations so that the programmer can make use of rapid prototyping techniques while still retaining excellent time and storage performance. Constraints and structured graphics are targeted by this research since studies show that these two techniques facilitate the rapid, iterative development of graphical user interfaces. This project is developing techniques whereby: (1) a profiler monitors operations as they execute and extracts information about constraint evaluation and variable access, and (2) an adaptive compiler uses this information to dynamically implement various performance and storage optimizations. ***
