Whether you are looking at crash simulations, implicit-explicit computations, or CFD analysis, all computing numerical solutions for very different physical models, they have in common, that the size of the data sets becomes bigger and bigger. This is true for the input data, the temporarily computed scratch files, and the final output data. Generally, I/O times have been considered small compared to the runs times of the solver. This may not be longer true today. Not all ISV codes propose a parallel I/O option, and if, it is not always easy to use.

Look for example at the StarCD input files for StarCD V3, V4 and finally StarCCM+ : The same geometry, a 34M cell case, uses 3.5GB for StarCD V3 .geom file and climbs up to 5.1GB when converted into the V4 .ccmg file (or the CCM+ .sim file).[Read More]
