From the FAQ:
2.2 How long does one workunit last?
This naturally depends on the speed of your computer. At the moment workunits may have different lengths. Some calculate 10,000 turns, others 100,000 turns and the rest calculate 1,000,000 turns around the accelerator. A job that calculates 1,000,000 turns will run approximately 10 hours on a 2 GHz processor.

2.3 Sometimes a workunit finishes in just a few minutes, why?
Some of the tested input data results in complete failure in the first loops. This is noted, and there is no sense to continue calculating the particles' orbits.

We cannot know in advance which work units will fail short. These short jobs are just as important to us as the others.
