Re: [deal.II] Re: measuring cpu and wall time for assembly routine

Happy about that! May I ask you to post the results here. I am curious since I never actually compared timings (and only blindly trusted Martin). Thanks, Peter On Saturday, 22 October 2022 at 16:46:16 UTC+2 Simon wrote: > Yes, the issue is resolved and the computation time decreased > signific

Yes, the issue is resolved and the computation time decreased significantly. Thank you all! -Simon Am Sa., 22. Okt. 2022 um 12:57 Uhr schrieb Peter Munch < peterrmue...@gmail.com>: > You are right. Release 9.3 uses the slow path for MappingQ. The reason is > that here > https://github.com/deali

Re: [deal.II] Re: measuring cpu and wall time for assembly routine

You are right. Release 9.3 uses the slow path for MappingQ. The reason is that here https://github.com/dealii/dealii/blob/ccfaddc2bab172d9d139dabc044d028f65bb480a/include/deal.II/matrix_free/fe_point_evaluation.h#L708-L711 we check for MappingQGeneric. At that time MappingQ and MappingQGeneric
