ppily with quad prec on your machine? How about one-way reductions?

Thanks for your suggestions.
I tried them all (declaring my variables as REAL*16 or REAL(16)) to no
avail. I still get the wrong answer with my call to MPI_ALLREDUCE

end
and checking if the output matches your expectations.

Hi,
I'm trying to do an MPI_ALLREDUCE with quadruple precision real and
MPI_SUM and open mpi does not give me the correct answer (vartemp
is equal to vartored instead of 2*vartored). Switching to double precision
real works fine.
My version of openmpi is 1.2.7 and it has been compiled with if
