Dear Pete,

Let me just focus on two of your questions.

The first one is related to the OpenMPI installation on Ubuntu 16.04 (and maybe other packages). You should not need more packages than what you list. However, it appears that the software shipped by Ubuntu is buggy. I can reproduce your error messages on my system (4.4.0-28-generic #47-Ubuntu SMP Fri Jun 24 10:09:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux):
$ cat test.cc
    int main() {}
$ mpicxx -fuse-ld=gold test.cc
/usr/lib/openmpi/lib/libmpi_cxx.so: error: undefined reference to 'opal_list_item_t_class' /usr/lib/openmpi/lib/libmpi_cxx.so: error: undefined reference to 'opal_class_initialize'
collect2: error: ld returned 1 exit status

This clearly is a bug in the OpenMPI implementation shipped by Ubuntu 16.04. I think someone should open a bug on the Ubuntu (or Debian?) bug tracker but I lack the time to do so right now...

However, it only appears when using the gold linker. If one disables the gold linker, everything works fine.
$ mpicxx test.cc
$

Pete, can you try to go to the file "cmake/checks/check_01_compiler_features.cmake" in the deal.II source directory, search for the line
  ADD_FLAGS(DEAL_II_LINKER_FLAGS "-fuse-ld=gold")
(it should be at the very end of that file), comment it out, and try to build again with OpenMPI?

I think using the gold linker on this configuration is a bug in the MPI detection of deal.II (we really should use all compile and link flags). I have opened an issue here:
https://github.com/dealii/dealii/issues/2820

Regarding using MPICH on Ubuntu: I once tried to use that instead of OpenMPI but it is not really straight-forward. I think many other Debian packages rely on OpenMPI, so my experience is that you cannot really avoid to have both MPI packages installed. The only way for me to get MPICH to work rather than OpenMPI was to put symbolic links to MPICH in my PATH before the system paths, i.e., not really an elegant solution. (BTW: I cannot really recommend MPICH because my experience was that it got miserably slow if the MPI is over-allocated, i.e., more MPI processes than CPUs on my system. While you will not usually use this for production runs, I was not able to run the deal.II test suite in a reasonable time frame.)

Best,
Martin

Wolfgang:

I installed:
sudo apt-get install libpetsc
sudo apt-get install petsc*
and
sudo apt-get install libopenlib
sudo apt-get install openlib*

I did not remove mpich since I assume since dealii was so specific in requiring the path info it shouldn't matter.

MPIhello world works ok.
gcc MPI-hello.c -I/usr/lib/openmpi/include /usr/lib/openmpi/lib/libmpi.so -o MPI-hello
./MPI-hello
Hello world from processor Ubuntu3, rank 0 out of 1 processors

I also have 7 questions relevant to future attempts at solving this problem. They are numbered below...

I ensured all the petsc and openmpi files as listed above were installed. I think they probably were before to since the rest of the tests are the same.1) Are there any others
required that you know of?

Expand dealii-8.4.1.tar.gz to dealii-8.4.1-PETSc
cd /dealii-8.4.1-PETSc
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/home/pgriffin/mylibs/dealii-8.4.1-PETSc -DDEAL_II_WITH_MPI=ON -DDEAL_II_WITH_PETSC=ON ../
make -j8 install

This seemed to go O.K. as always for the non-compiled version. Screen config results are attached in DealiiConfigWithPETScOpenmpi.txt.

then

make test

I again as before got the following error (below) when running the dealii tests:

===============< The dealii test error >========================

The results of the test are:

0% tests passed, 6 tests failed out of 6

Total Test time (real) =  92.47 sec

The following tests FAILED:
 1 - step.debug (Failed)
 2 - step.release (Failed)
 3 - affinity.debug (Failed)
 4 - mpi.debug (Failed)
 5 - tbb.debug (Failed)
 6 - step-petsc.debug (Failed)

all of the errors are of the form:

Complete screen results for test error in attached file DealiiTestWithPETScOpenmpi.txt.

2) Is this problem a dealii issue or should I contact petsc and/or openmpi development team, if mpich doesn't work.

============================================================================================

I saw another person had the same error under UBUNTU 16.04 used mpich and was successful.

But as I said dealii refuses to find mpich and only sees openmpi.

I tried to override using:

cmake -DCMAKE_INSTALL_PREFIX=/home/pgriffin/mylibs/dealii-8.4.1-PETSc -DMPI_DIR=/usr/lib/mpich -DMPI_ARCH=x86_64 -DDEAL_II_WITH_MPI=ON -DDEAL_II_WITH_PETSC=ON ../

3) Is this was the correct syntax to select an alternate MPI lib. My interpretation of the documentation is yes.

I next attempted to remove openmpi but that also removed petsc-dev, Why I don't know they can certainly be loaded separately but adding petsc-dev brought back openmpi.

4) I don't even know if petsc-dev... will work with mpich do you?
5) Is -DMPI_DIR=/usr/lib/mpich the correct way to select an alternate MPI library? 6) If it isn't correct and I still cannot remove openmpi without removing petsc do you think could rename the openmpi directory? 7) In general after installing or removing a package is a reboot required? I have never encountered a need in the past so I didn't.

Again In all cases I remove the entire dealii directory and unpack the dealii-8.4.1.tar.gz file again, etc...

Thanks again!
Pete Griffin

    I am trying to get PETSc running with dealii-8.4.1. (on Ubuntu
    16.04) Reading the documentation it looks
    like I don't need to have MPI. (???) I downloaded petsc-3.6.4 and
    most recently compiled it with:

    ./configure --with-cc=gcc --with-cxx=g++ --with-fc=gfortran
    --download-fblaslapack  --with-mpi=0

    This resulted in the following being created in

    Originally I compiled without the --with-mpi=0 and mpi libraries
    were created. The MPI version
    did not work! Since I am running on a single computer MPI was not
    needed and tried without it.

    
=================================================================================================

    The basic error is, with full details below:

    -- Found PETSC
    -- Could not find a sufficient PETSc installation: PETSc has to be
       configured with the same MPI configuration as deal.II.
    -- DEAL_II_WITH_PETSC has unmet external dependencies.
    CMake Error at cmake/configure/configure_3_petsc.cmake:110 (MESSAGE):

      Could not find the petsc library!

      Could not find a sufficient PETSc installation:

      PETSc has to be configured with the same MPI configuration as
    deal.II, but
      found:

        DEAL_II_WITH_MPI = OFF
        PETSC_WITH_MPI   = (NOT FALSE)
    ....


    I assume the -DDEAL_II_WITH_MPI=OFF switch would work since I
    created PETsc with
      --with-mpi=0 and since mpi files were not created.



    Thanks, Pete Griffin

    CMake Error at cmake/configure/configure_3_petsc.cmake:110 (MESSAGE):

      Could not find the petsc library!

      Could not find a sufficient PETSc installation:

      PETSc has to be configured with the same MPI configuration as
    deal.II, but
      found:

        DEAL_II_WITH_MPI = OFF
        PETSC_WITH_MPI   = (NOT FALSE)


      Please ensure that the petsc library version 3.0.0 or newer is
    installed on
      your computer and is configured with the same mpi options as deal.II

      If the library is not at a default location, either provide some
    hints

      for the autodetection:

      PETSc installed with --prefix=<...> to a destination:

          $ PETSC_DIR="..." cmake <...>
          $ cmake -DPETSC_DIR="..." <...>

      PETSc compiled in source tree:

          $ PETSC_DIR="..."  PETSC_ARCH="..." cmake <...>
          $ cmake -DPETSC_DIR="..." -DPETSC_ARCH="..." <...>

      or set the relevant variables by hand in ccmake.

=======================================================================================================================
    Originally I tried (and numerous other combinations):

    sudo apt-get install libpetsc3.6.2-dev
    and
    sudo apt-get install libopenmpi-dev

    all work well til:

    make test

    when a number of errors including:

    /usr/lib/openmpi/lib/libmpi_cxx.so: error: undefined reference to
    'opal_list_item_t_class'
    /usr/lib/openmpi/lib/libmpi_cxx.so: error: undefined reference to
    'opal_class_initialize'

    CMakeFiles/Makefile2:3571: recipe for target
    'tests/quick_tests/CMakeFiles/step.release.dir/all' failed

    resulted.


    sudo apt-get install libmpich-dev
    with
    sudo apt-get install libpetsc3.6.2-dev
    also had problems
