The cluster nodes (excluding inegi01-inegi02) are linked by a single Qlogic 12200 switch.

Each E5-2450 is capable of 134.4 GFLOPS, each E5-2650 is capable of 128 GFLOPS, each E5-2680v2 is capable of 448 GFLOPS. This gives the cluster a total performance of 5644.8 + 1792 + 896 = 8332.8 GFLOPS.

The Tesla M2075 provides a further 515 dual precision GFLOPS to give a total of 8847.8 GFLOPS.
