Hi Raymond, That is just a performance warning, but has absolutely no correctness implications. That comes from the tradeoff of performance vs. space. Sometimes we choose to pack a structure in spite of memory usage rather than optimizing access time to all of its fields, as we may consider that being of more interest. I hope this answers your question. Best, Antonio On 02/25/2014 04:48 AM, Raymond D Wright wrote:
Hello,
If I could ask a beginners question - I get this warning in "m.txt" at the end of doing "make":
sed -e 's/^C/\!/g' -e '/EXTERNAL/d' \ -e '/REAL\*8/d' \ -e '/DOUBLE PRECISION/d' \ -e '/MPI_WTICK/d' src/binding/f77/mpif.h > src/binding/f90/mpifnoext.h MOD src/binding/f90/mpi_constants.mod-stamp src/binding/f90/mpi_constants.f90(7): warning #6379: The structure contains one or more misaligned fields. [MPI_STATUS] TYPE :: MPI_Status ----------------^
Is it likely to cause trouble when I start using mpich?
(I need it for "hdf5","netcdf","io/api" as infrastructure to "models-3/cmaq")
