夸克-胶子等离子体是一种新的物质状态，在这种状态下，夸克不再局限于重子和介子等束缚态。就在大爆炸之后宇宙充满了夸克胶子等离子体。中子星的核心很可能是夸克-胶子等离子体。在布鲁克海文国家实验室（Brookhaven National Laboratory）的相对论重离子对撞机（RHIC）中，科学家们通过碰撞高能金光束来产生和研究夸克胶子等离子体。晶格规范理论家使用计算机研究夸克-胶子等离子体的性质，如产生夸克-胶子等离子体所需的温度及其状态方程。这些苛刻的计算将需要每年超过千万亿次的计算才能实现理论目标。
The quark-gluon plasma is a novel state of matter in which quarks are no longer confined to bound states such as baryons and mesons. Just after the Big Bang the Universe was filled with a quark-gluon plasma. The cores of neutron stars may well be a quark-gluon plasma. At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, scientists collide high energy gold beams to produce and study the quark gluon plasma. Lattice gauge theorists use computers to study to properties of the quark-gluon plasma such as the temperature required to produce it and its equation of state. These demanding calculations will require over a Petaflop-year of computing to achieve theoretical goals.
