Production systems
Ranger at the Texas Advanced Computing Center was the largest production Constellation system. Ranger had 62,976 processor cores in 3,936 nodes and a peak performance of 580 TFlops. Ranger was the 7th most powerful TOP500 supercomputer in the world at the time of its introduction.After 5 years of service at TACC, it was dismantled and shipped to South Africa, Tanzania, and Botswana to help foster HPC development in Africa.
A number of smaller Constellation systems are deployed at other supercomputer centers, including the University of Oslo.
