Exascale computing refers to a computer system capable of reaching performance of at least one exaflops. Such capacity would represent a thousandfold increase over the first petascale computer that came into operation in 2008 petascale[1] (one exaflop is a thousand petaflops). On the basis of a supercomputing conference held in December 2009, Computerworld projected its implementation by 2018.[2]

Development

In January 2012 Intel purchased the InfiniBand product line from QLogic for US $125 million in order to fulfill its promise of developing Exascale technology by 2018.[3]

The initiative has been endorsed by two US agencies: the Department of Energy and the National Nuclear Security Administration.[4] The technology would be useful in various computation-intensive research areas, including basic research, engineering, earth science, biology, materials science, energy issues, and national security.[5]

The United States has put aside $126 million for exascale computing beginning in 2012.[6]

Three projects aiming at developing technologies and software for Exascale Computing have been started in 2011 within the European Union. The CRESTA project (Collaborative Research into Exascale Systemware, Tools and Applications),[7] the DEEP project (Dynamical ExaScale Entry Platform),[8] and the project Mont-Blanc.[9]

The Indian Government has committed USD 2 Billion to ISRO and Indian Institute of Science (IISc), Bangalore to develop a supercomputer with a performance of 132.8 exaflops by 2017. ISRO has already booked key equipment to develop the first Indian exaflop supercomputer. Most of the sub-systems will be developed in India.[10]
