New question #95433 on DOLFIN: https://answers.launchpad.net/dolfin/+question/95433
Hi! I've been updating my dolfwave code from dolfin 0.9.2 to 0.9.5. Apart from some CGAL problems it is working, and I'm able to run some of the demos now. I've noticed a major slowdown from 0.9.2 to 0.9.5 (in my codes) Is this a known issue? I note that the solutions are the same for both versions. Using UMFPACK with factorized_solve I have the following summary of timings: dolfin 0.9.2: Summary of timings | Average time Total time Reps ----------------------------------------------------------- Assemble cells | 0.0046482 6.87 1478 Assemble exterior facets | 0.005 0.01 2 Build sparsity | 9.4723e-05 0.14 1478 Delete sparsity | 6.7659e-05 0.1 1478 Init dof map | 0 0 11 Init tensor | 6.7659e-06 0.01 1478 LU solver | 0.02 0.02 1 X:DOLFWAVE:END | 7.64 7.64 1 and for dolfin 0.9.5: Summary of timings | Average time Total time Reps ----------------------------------------------------------- Assemble cells | 0.011779 17.41 1478 Assemble exterior facets | 0.005 0.01 2 Build sparsity | 6.7659e-06 0.01 1478 Delete sparsity | 0 0 1478 Init tensor | 0 0 1478 LU solver | 0.03 0.03 1 X:DOLFWAVE:END | 85.12 85.12 1 Any ideas?!
