The problem seams to be a local MPI mixup. Dang, lost half a day with it. |

Make sure that fileBase encoded series also support the independent writes as in #554.
This is currently problematic with ADIOS1 (in CI) and HDF5 (not in CI since I need #569 for that).This causes interesting hang situations in WarpX particle flushes if one rank only writes attributes and other ranks actually write particles on first open.To Do
is this an MPICH 3.3a2 specific problem? even though CI looks good here, my local WarpX tests also hang when build with OpenMPI 3.1.5local MPI mix-up in depsFuture
