ON A CHIP
QCDOC was a massively parallel, custom-built machine. It consisted of low-power processing elements (500 MHz 440 PowerPC).
It was capable of focusing significant computing resources on relatively small but extremely demanding problems in the field of quantum physics.
The system WAS created TO SIMULATE LATTICE QUANTUM CHROMODYNAMICS.
In particle physics, CP (charge parity) violation is thought to be crucial in explaining why matter dominates over antimatter in the Universe and in the study of weak interactions in particle physics, which are the only type of known interactions breaking CP symmetry.
One of the processes that plays a central role in constraining the structure of the Standard Model (a theory of fundamental particles and how they interact) in the search for new physics is indirect CP violation in Kaon decays. Neutral Kaons can transform into their antiparticles and vice versa, however, this transformation does not occur with exactly the same probability in both directions.
The simulations that were run on QCDOC systems as a part of Riken-BNL-Columbia/UKQCD collaboration on the Kaon/anti-Kaon mixing parameter led to a reduction in the uncertainty in this parameter from around 15% to around 3.5%. Although we still do not know whether the Standard Model correctly predicts the CP violation in Kaons, reducing the uncertainty increases that probability.
The work to further improve the precision of Kaon mixing parameter (to around 0.5%) was performed on Blue Gene/Q.
