[Nek5000-users] MPI_TAG_UB

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

I checked the source (nekbone 3.1) and it looks like the fortran part does
not use any tagged messages but the C part does. In fact, there are C
parts using the MPI rank to tag messages.

So I am afraid commenting the check won¹t help.

Cheers,
Stefan
