RE: What is a Super Computer?

In actual fact, a supercomputer is not good at billing. The output to print is a linear process that doesn't parallelize very well. Supercomputers are good at forecasting the weather where the change in one location is based on prior conditions in neighboring locations. Easily modeled using the architecture Larry describes. The algorithm is highly mathematical and independent of external algorithms.

I have a theatre acquaintance who works for Cray here in Minneapolis. They claim they have the largest supercomputer. It's built of Intel graphic co-processors. Rumor is they burned down a rack late last year when heat dissipation methods failed. These things require their own electric sub-station, mainly to keep them cool enough to run. From a software development standpoint, the problem is how to run a debugger.

Our daily billing cycle would be complete before the operator's finger was off the ENTER key.

All those cores (each running a linux kernel) are communicating to
their 'neighbors' in 6 directions (in 3D) and simultaneously working
on a piece of the same problem. There is no traditional console with
Blue Gene, no USB port, no keyboard and no mouse. It also doesn't have
disk storage! All the programs are sent in over the network and
results come out the same way. The compute nodes are all linked very
tightly into a 'lattice' if you will.

"The IBM Sequoia supercomputer, installed at the Department of
Energy's

Lawrence Livermore National Laboratory, runs 16.32 petaflops, using
1.6 million compute cores in 96 racks, each roughly the size of a
large refrigerator, Parris said."

Okay, 1.6 million cores; that seems almost unbelievable. What makes
it

"one" computer? A single console? Something dispatching work to all
compute nodes?
