Dear libMesh developer team, Could someone please tell me what the current state about the item mentioned below is? I just want to know, so that I can decide whether I should wait or get around somehow or whatever.
(In the current state, my code does not show any speedup on 20 processors compared with 1 processor, because it spends apparently 95% of the time in EquationSystems::reinit().)
