Hello everyone,

I have been having some trouble using ABINIT with NetCDF in Linux. I am interested in outputting everything in NetCDF format, either by setting the `enable_netcdf_default="yes"` in the configuration stage, or by using `iomode 3` in the input file. This is my configuration file:

Code: Select all

enable_fallbacks="yes"
enable_gw-dpc="yes"
enable_macroave="yes"

enable_mpi="yes"
enable_mpi_io="yes"

enable_openmp="yes"

with_fft_flavor=fftw3
with_fft_incs="-I/usr/include/"
with_fft_libs="-L/usr/lib/x86_64-linux-gnu/ -lfftw3 -lfftw3f"

with_trio_flavor=netcdf
with_netcdf_libs="-L/usr/lib/x86_64-linux-gnu/ -lnetcdf -lnetcdff"
with_netcdf_incs="-I/usr/include/"
enable_netcdf_default="yes"

I configure with this:

Code: Select all

CC=mpicc FC=mpifort CXX=mpicxx ../configure

This compiles successfully, but when I run the tests using MPI, I get this error:

Code: Select all

--netcdf-default is on but netcdf library does not support MPI-IO. Aborting now

This has happened to me on various Linux systems using various compilers and libraries. I have tried to alleviate this problem by compiling NetCDF with parallel capabilities by hand and linking to that, but those attempts have been unsuccessful so far.

Surely there must be a way to launch ABINIT with MPI parallelism, but with sequential writing of the NetCDF files! Any help would be greatly appreciated.

Hi,

it seems that the "enable_netcdf_default" option involves netcdf-4 with a parallel hdf5
the netcdf package of ubuntu does not seem to support this configuration

below the ac file which contains the 4 configurations I tested:

only "config 4" works with "enable_netcdf_default="yes""

Code: Select all

enable_mpi="yes"
enable_mpi_io="yes"
with_mpi_prefix="/usr"

enable_openmp="yes"

with_fft_flavor=fftw3
with_fft_incs="-I/usr/include/"
with_fft_libs="-L/usr/lib/x86_64-linux-gnu/ -lfftw3 -lfftw3f"

I'm just found that there is a parallel netcdf lib ( libpnetcdf-dev ) : to try...

Thank you for the suggestions. Is there anyway to simply tell the program to not write the NetCDF files in parallel? That would definitely be the easiest solution...

Hi,

Is there anyway to simply tell the program to not write the NetCDF files in parallel?

simple answer : no

some more details...
libpnetcdf-dev : not usable because it's another paradigm

ubuntu packages : libnetcdf-dev + libnetcdff-dev + libhdf5-openmpi-dev + libhdf5-mpi-dev : don't work :-(

ubuntu didn't really compile the parallel support :roll:

I removed all installed packages by default (openmpi, hdf5, netcdf, ...) and I recompiled everything (MPICH3 + HDF5 + NetCDF + NetCDF-fortran ...) and then, everything works ...

The standard packages of ubuntu are not made for the "simulation" nor to make the HPC !!

if you need recipes to compile the different packages (HDF5, NetCDF, NetCDF-fortran, ...), I provide them

A+

That would be incredibly useful for me! My final install will be on a small HPC system using the Intel compilers.

Many thanks!

I would really appreciate these, if you have the chance. Thanks!
