Spain has unveiled plans to build the world's second most powerful computer.
The No 1 spot is taken by NEC's Earth Simulator in Japan
The supercomputer will be able to process 40 teraflops - 40 trillion calculations per second, equivalent to 18,000 personal computers.
The system will be at the heart of a centre to research climate change, medicine and industrial design.
The centre will be located in the wealthy north-east region of Catalonia, Spain's high-tech hub, and involves an investment of 70m euros ($87m).
The world's fastest computer is the Earth Simulator, created by NEC in Yokohama, Japan - dedicated to climate modelling and simulating seismic activity.
The Spanish computer, to be built over four years by IBM, will weigh 60,000kg and will occupy 120 square metres, according to El Pais newspaper.
It will use the Linux operating system, the government said.
"It will be the first supercomputer in the world for general use," Science and Technology Minister Juan Costa reportedly told a news conference.
He said Alzheimer's disease, mad cow disease and climate change will be among the top research priorities, though an independent scientific board will have the final say.
