ASCI White

It was almost exclusively used for large-scale computations requiring dozens, hundreds, or thousands of processors.

4U rackmount server could match these specifications while weighing under 50 kg and consuming under 2 kW of power.

Completed in June 2000 it was transported to specially built facilities in California and officially dedicated on August 15, 2001.

[2] Its peak performance of 12.3 TFLOPS was not achieved in the widely accepted LINPACK tests.

It was built as stage three of the Accelerated Strategic Computing Initiative (ASCI) started by the U.S. Department of Energy and the National Nuclear Security Administration to build a simulator to replace live nuclear weapons testing following the moratorium imposed by the Comprehensive Test Ban Treaty started by President George H.
