Chiral and deconfinement aspects of the QCD transition
We present results on the chiral and deconfinement properties of the QCD transition at finite temperature. Calculations are performed with 2 + 1 flavors of quarks using the p4, asqtad, and HISQ/tree…
An Overview of the BlueGene/L Supercomputer
An overview of the BlueGene/L Supercomputer, a massively parallel system of 65,536 nodes based on a new architecture that exploits system-on-a-chip technology to deliver target peak processing power of 360 teraFLOPS (trillion floating-point operations per second).
The HotQCD Collaboration
Overview of the Blue Gene/L system architecture
The key architectural features of BlueGene/L are introduced: the link chip component and five Blue Gene/L networks, the PowerPC® 440 core and floating-point enhancements, the on-chip and off-chip distributed memory system, the node- and system-level design for high reliability, and the comprehensive approach to fault isolation.
Blue Gene/L torus interconnection network
Both the architecture and the microarchitecture of the torus and a network performance simulator are described and simulation results and hardware measurements are presented.
Equation of state and QCD transition at finite temperature
We calculate the equation of state in $2+1$ flavor QCD at finite temperature with physical strange quark mass and almost physical light quark masses using lattices with temporal extent…
QCD phase transition with chiral quarks and physical quark masses.
The first lattice calculation of the QCD phase transition using chiral fermions with physical quark masses using 2+1 quark flavors, spatial volumes between (4 fm) and (11 fm)(3) and temperatures between 139 and 196 MeV finds no metastability near the peak and a peak height which does not change when a 5 fm spatial extent is increased to 10 fm.
Fluctuations and Correlations of net baryon number, electric charge, and strangeness: A comparison of lattice QCD results with the hadron resonance gas model
We calculate the quadratic fluctuations of net baryon number, electric charge and strangeness as well as correlations among these conserved charges in (2+1)-flavor lattice QCD at zero chemical…
Two-Nucleon Higher Partial-Wave Scattering from Lattice QCD
Quenched lattice QCD with domain wall fermions and the chiral limit
Quenched QCD simulations on three volumes, $8^3 \times$, $12^3 \times$ and $16^3 \times 32$ and three couplings, $\beta=5.7$, 5.85 and 6.0 using domain wall fermions provide a consistent picture of…
