[Nek5000-users] MPI_TAG_UB

Hi Neks, I was wondering if someone could tell me the implications of commenting this section of code out in Nekbone: if (nval.lt.(10000+max(lp,lelg))) then if(nid.eq.0) then write(6,*) 'ABORT: MPI_TAG_UB too small!' endif call exitt endif We are testing Nekbone with an experimental MPI library.
