New Super Computer Using 18,688 GPUs

The Titan supercomputer uses 18,688 Nvidia GPUs, has 6,329 miles of cable, cooled with 1,353 gallons of coolant, and stores data on 21,030 disks.

It is rated at more than 20 petaflops.

 

Anyone know why GPUs can have a couple thousand cores but a CPU has only 2, 4, or 6?

I bet even that computer wont run planetside 2 with 70+ stable frames :P

Think GPUs are designed to do many calculation intensive tasks very quickly, whereas CPUs are designed to do everything reasonably well.Most people have duel cores are the minute so writing programs for 4,6,8 cores cuts off alot of people from using it. Think that's why. :D

Most applications wouldn't benefit from having so many cores. But the one's that do, its a pain to design a program that effectively splits the processing over 6-8 cores.

Optimizing a program for multiple threads is......just terrible. I've had to write a simple programs to run on quad core machines and it was hard as crap keeping everything stable. Beyond that with something as complex as a game....I quit.
