High-performance computing tools
The Tera 100 supercomputer replaced the Tera 10 in October 2010. It was installed in the same buildings as the Tera 10. The infrastructure was adapted to accommodate the increase in power.
Tera 100 is the first European supercomputer to have passed the PetaFLOP mark of more than one quadrillion floating-point operations per second.
The Tera 100 can carry out more operations in one second than the world's population could in 100 hours at a rate of one operation per second and per person. The number of processors, RAM capacity, data storage capacity and speeds are all equally crucial to achieving such performance.
The Tera 100 is a cluster of 4,370 bullx S-series servers equipped with 17,480 Intel® Xeon® 7500 processors. Its main memory, which runs the computer codes, has more than 140,000 memory modules for a total capacity of 300 terabytes (TB). This equates to the RAM of around one million conventional computers. It has a storage capacity of 20 petabytes (1 PB equals 1,000 terabytes).
Additional means of visualization
CEA/DAM possesses a high-resolution video wall for viewing and analyzing results using high-performance image processing software.
