Awesome.
Years ago we were using cholmod without the eigen interface, it will be a revert... These cholmod/openblas issues make me nervous (not mentionning other attempts with Pardiso and Taucs, which all worked at some point). It still did not stabilize after 6+ years.


Do you think the GPU solver has benefits even with a standard graphical card, by the way?
Cheers
Bruno

Yes! We should be able to replace the Eigen cholmod interface entirely with the existing direct cholmod solver (useSolver=4). Right now the #ifdefs are configured for the special GPU build but I will generalize it today and commit it so that it can be used without GPU compilation flags. Cholmod is smart enough to revert to CPU on its own if GPU is not available.

I will install 18.04, test the solver, and report back with my findings today.

Best,

Robert

    Thank you very much for help Janek.
    I confirm that I could compile trunk on ubuntu18 with CGAL,
    without special steps (not even dpkg, just cmake+make without
    options).
    For DEM-PFV-check.py the problem is with the cholmod solver. I'll
    try and fix that.

    @Robert, you mentioned that by-passing the eigen interface to use
    cholmod directly solved issues on your side IIRC.
    Could you give more hints about that, do you have some candidate
    code for commit?

    OK, so I did the initial commit for cgal 4.11, the most
    importatnt stuff is in the commit message. I will repeat it here
    in short:

    1.  maybe the #ifdefs that I added in
    lib/triangulation/RegularTriangulation.h are not necessary?

    2. the ALPHASHAPES changes inlib/triangulation/Tesselation.h are
    not related to cgal, but I couldn't compile without this.

    3. In checkPolyhedraCrush.py this python line freezes:
         O.run(250, True); checkForcesBodies(25.44893, 4)

    Moreover:
    4. with this patch yade is compiling successfully with cgal 4.9
    and 4.11.

    5. regardless of cgal version (with 4.9 and 4.11) I have this
    error in DEM-PFV-check.py:

      running:  DEM-PFV-check.py

    Since it does not depend on cgal version, it must be some other
    library that I have on my workstation. I have here installed
    devuan ascii, and I only backported cgal 4.11 from devuan ceres.
    All other libraries are at their default devuan ascii version.

    6. Also  yade version is clean, right from github :) Just to make
    it all clear. However I could not compile yade just by doing the
    usual

      cd .. ; mkdir build ; cd build
      cmake -DCMAKE_INSTALL_PREFIX=../install ../trunk -DDEBUG=1
    -DCHUNKSIZE=5
      time nice -n 20 make install -j 20 ; xmessage "\nFinished\n"

    I had some boost errors related to the C++11 declytype support,
    eg. as discussed in:
    http://www.boost.org/doc/libs/1_66_0/libs/utility/utility.htm
    At first I was worried that g++ 6.3 is too old. However I found
    out that I can compile yade 2018-02 if I copy the ./debian/
    directory from yade 2017-01 and do:

       time dpkg-buildpackage -rfakeroot -b -j30

    So it must not be related to compiler version, but rather to
    compiler flags. And Anton fixed this in debian/ build rules,
    while my command could not make it correctly. I didn't figure
    this out yet. Last night I was simply building yade 2018-02 with
    debian/ from yade 2017-01 :)

                Should I work on latest yade trunk?

                    Hi Bruno,

                    CGAL_ 4.11 is the only version now for Debian
                    (testing) [1]
                    and upcoming Ubuntu 18.04 [2]. The shipped Yade does
                    not support CGAL due to compilation problems.

                    I am preparing the new Yade upload, but we have a
                    chance
                    to patch the Yade within the next two weeks or
                    prepare
                    the 2018.02b release with CGAL-support and upload it.

                        Thank you very much.
                        I'm not so sure what we are speaking about here.
                        Yade 2018.02a is the candidate source code
                        for producing a binary
                        yade-stable in Ubuntu 18.04, correct
                        (approximately)?
                        If yes, can we build yade-stable with CGAL at
                        the moment?
