In a word, no. In more words, not necessarily.
We continue to carry around our original mesh data structure as a "SerialMesh" object but have implemented a "ParallelMesh" flavor where all data structures are parallelized, which has been used successfully to thousands of cores. I don't want to quote a stale number and enrage the INL guys, so I'll let them comment from here. -Ben On Jul 14, 2014, at 12:32 PM, Hodge, Neil E. <[email protected]> wrote: > I recently sat down and read > > Kirk, "libMesh: a C++ library for adaptive mesh refinement/coarsening > simulations", Engineering with Computers, 2006. > > In that paper, I found the following: > > "On distributed memory machines, such as PC clusters, a complete copy of > the mesh is maintained independently on each processor.

Just curious, since the paper is from 2006 . . .
