Should we move the write below the return for ADIOS1?
Otherwise we create that empty ghost series.

It's a bit unfortunate, but we have to do it this way unfortunately, see write.backend() in the if condition. However, I can add a commit in #1043 that uses {"backend": "adios2"} to explicitly select backends up front.

I added that commit

if( ext == "bp" && write.backend() != "ADIOS2" )
if( ext == "bp" && write.backend() != "MPI_ADIOS2" )
{
// dataset resizing unsupported in ADIOS1
return;
