Abstract: 
Wiggins/Redstone(W/R) is a new software tool designed to automatically (without programmer intervention) improve the performance of applications by adjusting or 'specializing' the code for a single use on a particular machine. W/R does this on-line (while the application is executing) so that there is a performance gain the first time the application is used. W/R operates on unmodified binary applications, so that no special compiler support or user intervention is required. Like a whole-program optimizer, W/R uses profile information to guide program transformations. However, because the transformations are done while the program is running, with knowledge of data values, W/R can exploit temporal changes. For example, while running an animation application W/R may change the code as objects move in and out of the frames.
