First To TeraFlop
In December, 1996, three quarters of ASCI Red was measured at a world record 1.06 TFLOPS on MP LINPACK and held the record for fastest supercomputer in the world for several consecutive years, maxing out at 2.38 TFLOPS after a processor and memory upgrade in 1999. The system utilized Pentium Pro processors when initially constructed and when it recorded performance above one TeraFlop. In that configuration, when fully built it recorded 1.6 TeraFlops of performance. Upgrades later in 1999, to specially packaged Pentium II Xeon processors, pushed performance to 3.1 TeraFlops.
