Thank you very much! If I do not use "adaptive coarsening", just only use mesh data structure. Whether parallel mesh can work with 10K CPUs? Regards -- Fande Kong ShenZhen Institutes of Advanced Technology Chinese Academy of Sciences -- Original

Hello- It appears that this topic came up before, but I did not see a resolution. Anyway, I have a few mesh and solution xda files that I created back in (about) August that do not seem to read in correctly. I don't know what version of libMesh I was using then, but the headers of these files say

Sorry, in my previous post I was not too specific. I need to write out a complex valued vector. I write out my data using MeshData::write(**), which in my case calls MeshData::write_xdr(**), which calls Xdr::data(**). By doing so in the former libmesh version, the vector entries were written out

Browsing the localize source for the petsc vector implementation reveals a really old implementation involving a parallel sum. We should definitely replace this with a Parallel::allgather(). Do you guys have code which localizes to a std::vector<>? -Ben
