dynamical, anisotropic lattices. A
convenient set of coordinates that parameterize the two-dimensional plane of light and strange-quark
masses is introduced. These coordinates are used to extrapolate data obtained at the simulated values of
the quark masses to the physical light and strange-quark point. A measurement of the Sommer scale on
these ensembles is made, and the performance of the hybrid Monte Carlo algorithm used for generating
the ensembles is estimated. | en |
| dc.description.sponsorship | This work was done using the
CHROMA
software suite
[

] on clusters at Jefferson Laboratory using time
awarded under the USQCD Initiative. We thank Andreas
Stathopoulos and Kostas Orginos for implementing the
EigCG inverter [

] in the
CHROMA
library, which greatly
sped up our calculations. This research used the resources
of the National Center for Computational Sciences at Oak
Ridge National Laboratory, which is supported by the
Office of Science of the Department of Energy under
Contract No. DE-AC05-00OR22725. In particular, we
made use of the Jaguar Cray XT facility, using time allo-
cated through the U.S. DOE INCITE program. This re-
search was supported in part by the National Science
Foundation under Contract Nos. NSF-PHY-0653315 and
NSF-PHY-0510020 through TeraGrid resources provided
by Pittsburgh Supercomputing Center (PSC), San Diego
Supercomputing Center (SDSC), and the Texas Advanced
Computing Center (TACC). In particular, we made use of
the BigBen Cray XT3 system at PSC, the BlueGene/L system at SDSC, and the Ranger Infiniband Constellation
Cluster at TACC. J.B., J.F. and C.M. were supported by
Grant Nos. NSF-PHY-0653315 and NSF-PHY-0510020;
E.E. and S.W. were supported by DOE Grant No. DE-
FG02-93ER-40762; N.M. was supported under Grant
No. DST-SR/S2/RJN-19/2007. M.P. and S.R. were sup-
ported by the Science Foundation Ireland under research
Grant Nos. 04/BRG/P0275, 04/BRG/P0266, 06/RFP/
PHY061, and 07/RFP/PHYF168. M.P. and S.R. are ex-
tremely grateful for the generous hospitality of the theory
center at TJNAF while this research was carried out. This
work was supported by DOE Contract No. DE-AC05-
