Signage and view of the "Ranger" computer cluster at TACC

Ranger at the Texas Advanced Computing Center (TACC) was the largest production Constellation system. Ranger had 62,976 processor cores in 3,936 nodes and a peak performance of 580 TFlops.[1][2] Ranger was the 7th most powerful TOP500 supercomputer in the world at the time of its introduction.[3] 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.[4]

A number of smaller Constellation systems are deployed at other supercomputer centers, including the University of Oslo.[5]
