Bridge++ is a general-purpose code set for lattice QCD simulations aiming at a readable, extensible, and portable code while keeping practical high performance. The new version 2.0 employs machine-dependent optimization, enabling flexible data layout in float/double precision, while it was fixed layout and only with the double precision in previous versions. We report the performance on supercomputer Fugaku with Arm A64FX-SVE architecture by Fujitsu.

Quark number susceptibility and conserved charge fluctuation for (2+1)-flavor QCD with M\"obius domain wall fermions
hep-lat 2025-01 conditional novelty 6.0 of 10

New lattice QCD results for second- and fourth-order quark number susceptibilities and charge fluctuation ratios using Möbius domain wall fermions show a possible discrepancy with staggered fermions in the electric ch...
