[Beowulf] Servers Too Hot? Intel Recommends a Luxurious Oil Bath

There is thousands of traders in each nation and they all have a  
datacenter that is doing simulations on how to make money.
Most traders are at several exchanges.

A single tad larger trader typically has a 3000 machines and they're  
all equipped with a highspeed network.

As slowly trader by trader is simply getting kicked bigtime by the  
traders that do have those 3000+ machines in their own datacenter,
one by one they are all setting up their own calculation centers with  
more machines to do those simulations figuring out whether their
package, based upon previous data, can make them big cash tomorrow on  
the exchanges.

In most nations the high frequency traders will have the majority of  
the HPC hardware. More than government.
