CHAPTER 6 Checkpointing
Computers today are thousands of times faster than they were just a few decades ago. Despite this, many important applications take days or more of computer time. Indeed, as computing speeds increase, computational problems that were previously dismissed as intractable become practical. Here are some applications that take a very long time to execute, even on today’s fastest computers.
1. Fluid-Flow Simulation. Many important physics applications require the simulation of fluid flows. These are notoriously complex, consisting of large assemblages of three-dimensional cells interacting with one another. Examples include weather and climate modeling.
2. Optimization. Optimally deploying resources is often very complex. ...
