[Nek5000-users] possible bug

[nek5000-users at lists.mcs.anl.gov]

Hi Frank,

I am sure you'll find more things in mpi_dummy.f which are not consistent. It's just an ugly hack to run NEK in serial w/o using a MPI library. However only a few routines in the dummy lib are actually used.

Your compiler is right, the data types to not agree here. However you're just passing the arguments to another routines so it should be ok even though the datatypes do not match. You can think of it as passing a pointer.
