Table 9 Time to convergence of GCR for each preconditioner on GPGPU and CPU

From: Newton–Raphson preconditioner for Krylov type solvers on GPU devices

  DIAG (GPU) BFGS–DIAG (GPU) SSOR (CPU)
\(100^3\) 2.89E+02 5.27E+01 1.46E+02
\(200^3\) 8.23E+03 9.50E+02 3.88E+03
  1. In the table, e.g. 5.14E−02 means \(5.14 \times 10^{-2}\) s
