Path optimization method for the sign problem: Insights from random matrix models
Kouji Kashiwa, Yusuke Namekawa, Hayato Takase
The path optimization method is applied to the Stephanov model and the chiral random matrix model, both of which share several properties with QCD, to mitigate the sign problem cau…

Mixed precision solvers with half-precision floating point numbers for Lattice QCD on A64FX processor
Issaku Kanamori, Hideo Matsufuru, Tatsumi Aoyama +4
We investigate the use of half-precision floating-point numbers (FP16) in mixed-precision linear solvers for lattice QCD simulations. Since the emergence of GPUs for general-purpos…
