10 Top Expensive Super Computers in the world

4. Sierra and Summit (US) – $325 million

Currently, China’s Tianhe-2 supercomputer is the world’s fastest, able to deliver 55 PFLOPS of power, which is twice more than the second on the list. The upcoming Sierra system will have no problem running at over 100 PFLOPS, while Summit will have processing capabilities of as much as 300 PFLOPS. Sierra’s purpose at the Lawrence Livermore National Laboratory will be to ensure safety and effectiveness of (you guessed it) the nation’s nuclear program. Meanwhile, Summit will the Oak Ridge National Laboratory’s aging Titan supercomputer, meant for scientific applications around the world.
