The reason is simple: Even at hundreds of millions of dollars, inefficient hardware configuration is still cheaper than re-engineering the code and retraining the scientists to program their experiments and use current technology. In supercomputing, Moore's law prevails. The reality of effective and efficient compute capability depends upon the close coupling of current hardware and software technologies. These current technologies will not be generally seen in supercomputing for 5 - 10 years, perhaps longer, until both current and emerging paradigms can be adopted by the user community. Flynn's taxonomy, including MIMD is simply inadequate to this task, IMO. Kenneth A. Lloyd Watt Systems Technologies Inc.
