Tera 100

Tera 100 is a supercomputer built by Bull SA for the French Commissariat à l'Énergie Atomique.
On May 26, 2010, Tera 100 was turned on. The computer, which is located in Essonne is able to sustain around 1 petaFLOPs maximum performance and a peak at 1.25 petaFLOPs. It has 4300 Bullx Series S servers ('Mesca'), 140,000 Intel Xeon 7500 processor cores, and 300 TB of memory. The Interconnect is QDR InfiniBand. The file system has a throughput of 500 GB/s and total storage of 20 PB. It uses the SLURM resource manager for scheduling batch jobs.
Tera 100 uses Bull XBAS Linux, a partly Red Hat Enterprise Linux derivative.
In June 2011, TOP500 deemed it the ninth fastest supercomputer in the world, and in 2020, it had dropped off the list.
