Trace estimation in lattice QCD benefits from two complementary variance-reduction techniques: probing methods that exploit operator structure, and multigrid multilevel Monte Carlo, an efficient deflation technique. We propose a unified framework that combines these ideas and evaluate it on three representative targets: the trace of the inverse of the Dirac operator, traces entering the...

The conjugate gradient (CG) algorithm, employing mixed precision and even-odd preconditioning, is typically used when computing propagators for highly improved staggered quarks (HISQ). However, its performance degrades due to critical slowing down as the light quark mass approaches its physical value. In previous work, we addressed this issue using deflation, which significantly reduced solve...

Lattice quantum chromodynamics (LQCD) calculations are pushing the limits of today’s most powerful supercomputers. Since most resources are consumed in solving large systems of linear equations, efficient solvers, such as those based on adaptive multigrid methods, are essential. However, with the slowdown of Moore’s Law, it is uncertain whether traditional architectures can deliver the...

The evolution of GPU architectures has fundamentally transformed computational capabilities for Lattice QCD simulations. Over recent generations, GPU memory bandwidth has increased by approximately one order of magnitude, with modern systems achieving terabytes per second of memory throughput, while computational width has expanded significantly. These advances, driven primarily by artificial...

Recent global events have shown how easily access to critical technologies can be disrupted - whether due to trade restrictions, export controls, or the conflicting obligations of multinational corporations caught between multiple jurisdictions. These developments highlight a profound truth: a nation’s digital future cannot be secure, inclusive, or self-reliant if its foundational technology...
