TeraGrid is a national-scale computational science facility supported through a partnership among thirteen institutions, with funding from the US National Science Foundation . Initially created through a Major Research Equipment Facilities Construction (MREFC ) award in 2001, the TeraGrid facility began providing production computing, storage,… (More)
Human umbilical vein endothelial cells (HUVEC) were used as an experimental host model to investigate the mechanism(s) of streptococcal adhesion in infective endocarditis. Adhesion activity of Streptococcus gordonii was maximal during the logarithmic phase of growth and was greatly reduced or eliminated by pretreatment of bacteria with heat, formaldehyde,… (More)
Parity-odd domains, corresponding to nontrivial topological solutions of the QCD vacuum, might be created during relativistic heavy-ion collisions. These domains are predicted to lead to charge separation of quarks along the system's orbital momentum axis. We investigate a three-particle azimuthal correlator which is a P even observable, but directly… (More)
The STAR level-3 trigger is a MYRINET interconnected ALPHA processor farm, performing online tracking of N 58000 particles (N 445 per track) with a design input rate of R"100 Hz. A large-scale prototype system was tested in 12/99 with laser and cosmic particle events. 2000 Published by Elsevier Science B.V. All rights reserved.
The Data SuperCell (DSC) is a new, disk-based data archive deployed and in production at the Pittsburgh Supercomputing Center (PSC). It specifically deals with the archival demands of large data processing in an economic way. DSC incorporates PSCs SLASH2, layered filesystem technology, with commodity hardware and open software, to provide superior… (More)
We report the first three-particle coincidence measurement in pseudorapidity (Δη) between a high transverse momentum (p⊥) trigger particle and two lower p⊥ associated particles within azimuth |Δϕ|<0.7 in square root of s(NN)=200 GeV d+Au and Au+Au collisions. Charge ordering properties are exploited to separate the jetlike component and the ridge (long… (More)
We report the first measurements of the kurtosis (κ), skewness (S), and variance (σ2) of net-proton multiplicity (Np-Np) distributions at midrapidity for Au+Au collisions at square root of s(NN)=19.6, 62.4, and 200 GeV corresponding to baryon chemical potentials (μB) between 200 and 20 MeV. Our measurements of the products κσ2 and Sσ, which can be related… (More)
The status of the IEEE 802.3 standard is reviewed and prospects for the future, including the new 10 Gigabit version of Ethernet, are discussed. The relevance of Ethernet for experiments at the CERN Large Hadron Collider is considered, with emphasis on on-line applications and areas which are technically challenging.
In this paper, we describe <i>Bridges</i>, a new HPC resource that will integrate advanced memory technologies with a uniquely flexible, user-focused, data-centric environment to empower new research communities, bring desktop convenience to HPC, connect to campuses, and drive complex workflows. <i>Bridges</i> will differ from traditional HPC systems and… (More)
Rapidity-odd directed flow (v1) measurements for charged pions, protons, and antiprotons near midrapidity (y=0) are reported in sNN=7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions as recorded by the STAR detector at the Relativistic Heavy Ion Collider. At intermediate impact parameters, the proton and net-proton slope parameter dv1/dy|y=0 shows… (More)
