OF INTEREST: 10 years old and counting on its 50,000 processors

​When ITER scientists needed to simulate how particles travel and transport radiation in the ITER machine, they bought time in one of the most powerful supercomputers in Europe: Mare Nostrum (link), the flagship machine of the Barcelona Supercomputing Centre (BSC).

The collaboration with the Spanish public institution, whose 10th anniversary was celebrated on 1 April, has now shifted to simulation studies of ELM control techniques — another field of study that requires crunching huge quantities of numbers.

High performance computing has become essential to the progress of science and technology. With close to 50,000 processors and a computing power of one thousand billion operations per second, Mare Nostrum has contributed to establishing three-dimensional maps of the galaxy, mathematical models of the expansion rate of the Universe, the sequencing of the human genome…

In a video address to the participants of the 10th anniversary ceremony, ITER Director-General Bernard Bigot stressed the importance of BSC’s contribution to ITER.

ITER and the Spanish institution have crossed ways many times: former ITER Deputy-Director Carlos Alejaldre was part of BSC’s executive board in the mid-2000s and, more recently, one of the ITER Monaco Postdoctoral Fellows joined BSC’s computational physics group, bringing with him the valuable experience he gained while at ITER.
