There's a difference between megahertz...

[RodgerTheGreat]

and computing power. Before I get on a rant about the megahertz myth and why I love PowerPC's, the real reason Crays were powerful was their massive parallelism and the use of path optimization (premeasured cables and careful curcuit designs that made the distance electrons had to travel equal between parts of the machine) was the real reason they were a Cray.

Just because your machine is *faster* doesn't mean it's anywhere near as powerful! How many CPU cores does your machine have? I bet the cray had more. Clockspeed means *nothing*. The reason those applications don't exist is because they would take an order of magnitude as long to calculate on your "old computer".

I recommend you do some reading on supercomputing-http://en.wikipedia.org/wiki/Superc omputing

"Supercomputers traditionally gained their speed over conventional computers through the use of innovative designs that allow them to perform many tasks in parallel, as well as complex detail engineering. They tend to be specialized for certain types of computation, usually numerical calculations, and perform poorly at more general computing tasks. Their memory hierarchy is very carefully designed to ensure the processor is kept fed with data and instructions at all times--in fact, much of the performance difference between slower computers and supercomputers is due to the memory hierarchy design and componentry. Their I/O systems tend to be designed to support high bandwidth, with latency less of an issue, because supercomputers are not used for transaction processing."
