There is a limit to processor speed and so the only way to get the above is
to connect many processors with a fast communication switch between them.
Either the system itself,(demanding fast communication between the parts) or the
realizations are shared out. There is a limit to a students ability to do bookeeping for many runs and a single machine with many identical nodes makes this realistic.
Example at left: to study a LONG nanotube for LONG runtimes - divide it between processors.
After years of delay we got first NANCO and now TAMNUN for the TECHNION
and as the icing on the cake Israel has recently become a partner in PRACE,
the European Supercomputer sharing community.
See the real TAMNUN
homepage on the Computer Center Site.
