Berger and colleagues in the College of Information and Computer Science (CICS) expect Mesh to have a substantial impact on the computing world, from mobile applications to desktops to data centers, because no one has previously been able to compact memory in applications written in or running on top of widely-used languages like C, C++, or Objective C, the language used for iOS apps.

As the authors explain, programs written in C-like languages can suffer from serious memory fragmentation, where memory is broken up, much like a bad Tetris board, Berger says, so there are many empty gaps in between. "This is how memory gets wasted," he points out. "Imagine a Tetris board where you could stop and reorganize it at any time -- this would make the game a lot easier, because you could always squeeze out the empty space. But you can't do this in C, just as you can't do it in Tetris."
