For parallel layouts generally each MPI rank (parallel process) will have
roughly the same number of indices for each field. So you would not end up with
entire fields on one or a small number of processes. This is done by using
interlaced (check the docs) storage of variables rather by

Hi, I am currently using fieldsplit and I am creating the fields using
ISCreateGeneral.programming is being carried out in FORTRAN. I have a
couple of questions regarding fieldsplit in parallel.
Do we need to create the index list of all the fields separately for each
processor?
For example, say
