FlashMob Computing started as a challenge. Could we convince enough people to bring their conventional computers to a single location in order to build a temporary supercomputer, one that could compete with the fastest and most expensive computers in the world? Since its inception in February of this year, the idea of FlashMob Computing transformed from a challenge to a new paradigm for enabling any group of people to pool together computing power for the purpose of working on scientific problems of interest to them. Unlike traditional supercomputers, which are expensive and not accessible to the general public, a FlashMob supercomputer is temporary, made up of ordinary computers, and is built to work on a specific problem. We set out to prove, through an elaborate experiment, that instant supercomputing is viable.
