Researchers in MIT's Department of Mechanical Engineering have developed a software that can perform such simulations on an ordinary smart phone. "New software that runs on a smart phone can approximate in seconds computations that would take a supercomputer hours. The software works for problems whose form is know but whose particulars aren't; slider bars allow users to set the values for which they want the problems solved." The new software works in cases where the general form of a problem is known in advance, but not the particulars.
The goal here's to let researchers and scientists convert to Google's mobile OS, but if you aren't falling for that one, it's also designed to "let engineers perform complicated calculations in the field, and to better control systems for vehicles or robotic systems."
