Tera-10

TERA-10 is a supercomputer built by Bull SA for the French Commissariat à l'Énergie Atomique,.
TERA-10 was ranked 142nd on the TOP500 list in 2010. By 2015 it had dropped off the bottom of the list. During its operational period, it ran at 52.84 teraFLOPs using nearly 10,000 processor cores. It runs the Linux operating system, with an SMP kernel specially modified to handle very large symmetric clusters.
Its main application is the simulation of atomic experiences and the maintenance of the French nuclear defence force, using the results of true nuclear tests and the new results obtained from the LMJ built in continental France.

Evolution

Evolution TERA-10 represented the end of its generation's evolution. It was succeeded by the next generation, Tera-100, which reached about 1 petaFLOPS. The Tera-100 utilizes processors with more internal cores and a new central scheduling system, which allows asymmetric operation on a variable number of processors. This design was implemented for easier upgrades, lower maintenance cost, and more experiences requiring different computing scales, without having to rebuild the whole cluster.
