Most high-end scienTific apps are written by scientists. Some very large, later generation applications have software engineers and computer scientists involved, but in general it's actual scientists who write the majority of the code. > Are they batch-based, command line apps or GUI driven? Most of the computation can be started from a command line, but the mode of operation varies from applications which take a single set of inputs and run for days on hundreds of nodes to applications where a script feeds multiple runs into a batch queueing system. Generally, there is a visualzation component, but how it works varies significantly. Some systems visualize after computation, others allow visualization during, and yet other have interactive visualzations which steer the computation. There's no one true way. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
