Download scientific diagram | A 2D illustration of using padded field to capture the snake terms. The orange and purple squares represent non-zero sites, and the white space represent zero sites. Black arrows represent the stencils relevant to the Dirichlet boundary condition. The stencil operators are not applied to the grey areas as they are either zero (as in 2)) or not needed for the output field at the center (as in 5) and 6)). from publication: Solving DWF Dirac Equation Using Multi-splitting Preconditioned Conjugate Gradient with Tensor Cores on NVIDIA GPUs | We show that using the multi-splitting algorithm as a preconditioner for the domain wall Dirac linear operator, arising in lattice QCD, effectively reduces the inter-node communication cost, at the expense of performing more on-node floating point and memory operations. | Preconditioning, Conjugation and Gradient | ResearchGate, the professional network for scientists.
