QB2 came on-line 5 Nov 2014. It is a 1.5 Petaflop peak performance cluster containing 504 compute nodes with 960 NVIDIA Tesla K20x GPU's, and over 10,000 Intel Xeon processing cores. It achieved 1.052 PF during testing, and premiered at number 46 on the November 2014 Top500 list. The system is housed in the state's Information Systems Building (ISB), located in Baton Rouge.

***UPDATE*** In order to accommodate the power and cooling requirements of the QB3 cluster, 128 QB2 compute nodes were retired in March 2020.
