Just a few thoughts on this ongoing debate -

  Eugene Brooks is claiming that the R6000 is (probably) faster than any 
other computer for ONE specific simulation that he runs. He describes this 
as a packet-switched network simulation, almost completely scalar. 

Claims that {supercomputer X} runs {FP app Y} faster don't alter this 
claim. 

Claims that {super X} has much more memory or much more I/O bandwidth than 
the R6000 are probably irrelevant as well, as event-driven simulations (I 
assume a PSN simulator would be event-driven) may not need the amounts of 
memory and I/O that other types of simulations require.

[Gross generalization. However, consider that in many scientific codes - 
e.g. weather simulations - you can increase the simulated detail, and 
hence accuracy and memory requirements, by decreasing the grid size. To do 
the equivalent with an event-driven simulation may require describing the 
finer detail yourself in code.]

In other words, Eugene may not be comparing apples to oranges; however, he 
is discussing the merits of his apple in a conference full of orange 
growers :-)
