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 Am 8/18/16, 8:55 AM schrieb "[email protected] on behalf of [email protected]" unter <[email protected] on behalf of [email protected]>:
Basically, the MPI library that we are testing sets MPI_TAG_UB=65534, which is quite low to be used with higher numbers of lp.

To answer your question I need to know why you want to comment this check?

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.
Regards, Ken
