If I understand it correctly you want to run parallel task where DOLFIN
objects does not feel parallel. Then you could use my experimental
branch lp:~blechta/dolfin/serial-meshes. It is implemented in a rather
hacky way but it should work for your needs. It also has two demos...

Dear Jan,
That's exactly what I need. I tried to rewrite your code in C++ but you did some changes in MPI.cpp, GlobalParameters.cpp,... How to put these changes in the code? I attached the script and the error message.
Thanks for your help,
Best regards,
Dang

You need to pull the branch using bazaar and compile it. It is
basically same procedure like
http://fenicsproject.org/download/installation_from_source.html#installation-from-source
or
http://fenicsproject.org/download/installation_using_dorsal.html#installation-using-dorsal
but taking branch lp:~blechta/dolfin/serial-meshes instead of
lp:dolfin/1.1.0.

You need to choose other components compatible with dolfin 1.1.0. These
are:
UFL 1.1
UFC 2.1
FFC 1.1
Instant 1.1

Dear Jan,
I downloaded and installed the newest dorsal here https://launchpad.net/dorsal but it failed in the middle

common.copy /home/dang1032170/Work/FEniCS/include/boost/tr1/tr1/algorithm
...failed updating 30 targets...
...skipped 6 targets...
...updated 9740 targets...
Failure with exit status: 1
Exit message: There was a problem building boost_1_47_0.

Moreover, I am still confused about "taking branch lp:~blechta/dolfin/serial-meshes instead of
lp:dolfin/1.1.0.". It means that I have to change the directory somewhere? Can you please show me more details?

Thanks a lot,

Navigate to boost src dir and check dorsal_configure.log and
dorsal_build.log for a cause of error.

First of all you need to start from FEniCS 1.1.0 instead of development
release trunk or stable release 1.2.0 as serial-meshes branch will not
probably work with them.

You could switch to dorsal which downloads stable release 1.1.0.
1. Install bzr.
2. Get branch of dorsal at revision 830
     cd /your/work/path
     bzr branch -r 830 lp:dorsal
3. Set in dorsal.cfg STABLE_BUILD=true and tweak your platform file
   for optional packages you need.
4. Build with dorsal
     ./dorsal.sh FEniCS/platforms/supported/your.platform
5. Atter you succeed building go to dolfin dir and switch to
   serial-meshes branch
     cd /your/work/path/fenics/src/dolfin
     bzr branch --use-existing-dir lp:~blechta/dolfin/serial-meshes .
   (note . on the end of line)
6. Rebuild only dolfin
     cd /your/work/path/fenics/src/dolfin
     ./dorsal_build
7. Try running serial-meshes demo.

Maybe Johannes would know clever solution to get 1.1.0 a switch dolfin
to custom branch.

Did you read dorsal instructions shown before pulling boost to fetch
dependencies?

I guess there is some problem with python dependency. But I never
installed boost from scratch.

@Jan: I don't know if it's a better solution, but before step 4 you could modify FEniCS/packages/dolfin.package like this:

  -NAME=dolfin
  -SOURCE=lp:
  +NAME=serial-meshes
  +SOURCE=lp:~blechta/dolfin/

Then step 5 and 6 can be skipped.

@Dang: Jan is probably right. It looks like you are missing Python.h, which should be installed by the python-dev package.

Plus
rm FEniCS/packages/dolfin-stable.package
otherwise dorsal will not look into FEniCS/packages/dolfin.package

Yes. Or you can build everything except DOLFIN, then change STABLE_BUILD=false in dorsal.cfg and then only build DOLFIN.

Dear Jan and Johannes,
I succeeded building all packages listed in lucid.platform except dolfin with following errors:

I removed dolfin-stable.package and used following information
In dorsal.cfg

In dolfin.pakage

README.Bugs is manual for submitting bugs to developers of GCC. It is
not useful here. What is in dorsal_configure.log and dorsal_build.log?

Is gcc-4.4 supported, Johannes?

@Jan: Yes, we build and run tests with gcc-4.4 on the buildbot (lucid-amd64 has gcc 4.4.3 and squeeze-amd64 has 4.4.5).

@Jan: Here is the dorsal_build.log file I got from Work/FEniCS/src/boost_1_51_0/. The file dorsal_configure.log is empty.
https://transfert.inria.fr/fichiers/30bca61f47ad81befea4d2873aa6096a/dorsal_build.log

That was the build log for Boost, which does not contain any errors. In post #13 it looks like it was DOLFIN that failed. Post dorsal_configure.log and dorsal_build.log for DOLFIN instead.

I mean the dorsal_configure.log and dorsal_build.log from dolfin src
dir. It would be in something like Work/FEniCS/src/dolfin/ or
Work/FEniCS/src/serial-meshes/

Dear Jan,
Here are two files I got from /home/dang1032170/Work/FEniCS/src/serial-meshes/

The problem might be that you ran out of memory. Try again, but if the same thing happens, you might need to disable CGAL.

Dear Johannes,
I registered SSH at https://launchpad.net/~dang-1032170 and tried bzr launchpad-login dang-1032170 without warnings, error messages.
Then, I built again ./dorsal.sh FEniCS/platforms/supported/lucid.platform
I got these messages at the end:
ssh: connect to host bazaar.launchpad.net port 22: Connection timed out
bzr: ERROR: Connection closed: Unexpected end of message. Please check connectivity and permissions, and report a bug if problems persist. Can you please tell me how to fix it? It works if I disable CGAL? If yes, how to disable it?
Thanks a lot,

That seems like problem on launchad or with your ssh.

You don't have to ssh to launchpad if you already have source code of
serial-meshes branch. You don't even have to execute dorsal.sh and
build everything from beginning. Just execute ./dorsal_cofigure
&& ./dorsal_build in serial-meshes src dir.

Alternatively you can prepend skip: to lines in platform file which you
don't need to be rebuild. Check dorsal documentation for this feature.
It will save you lot of time.

First free some memory and try rebuilding by ./dorsal_build in
serial-meshes src dir.

You can disable CGAL in
file /src/serial-meshes/dorsal_build_dir/CMakeCache.txt by changing
DOLFIN_ENABLE_CGAL

Did you tell to bzr your own launchpad login?
  bzr launchpad-login dang-1032170

Yes, I did but I still got the errors.

It seems like a problem with your ssh.

Are you able to do in some temp dir
branch lp:dolfin
and
branch lp:~blechta/dolfin/serial-meshes
?

Dear Jan,
The problem of ssh was solved since I worked with another proxy. However, I could not finish the installation with following erros:

error: ‘smartarg1’ was not declared in this scope
make[2]: *** [dolfin/swig/modules/mesh/CMakeFiles/_mesh.dir/modulePYTHON_wrap.cxx.o] Error 1
make[2]: Leaving directory `/home/dang1032170/Work/FEniCS/src/serial-meshes/dorsal_build_dir'

make: *** [all] Error 2
make: Leaving directory `/home/dang1032170/Work/FEniCS/src/serial-meshes/dorsal_build_dir'

Here are .log files I got from /home/dang1032170/Work/FEniCS/src/serial-meshes
https://transfert.inria.fr/fichiers/52a18b612998c79ce5883bb9bb428b4c/dorsal_build.log
https://transfert.inria.fr/fichiers/7d0b3fbf5c8e8aa11f361c5b6d7ea03a/dorsal_configure.log

Then, I set DOLFIN_ENABLE_CGAL:BOOL=OFF (in /home/dang1032170/Work/FEniCS/src/serial-meshes/dorsal_build_dir/CMakeCache.txt) and rebuilt: ./dorsal_build
but I still got the same errors.
Can you please help me again?
Thanks,
Best regards,
Dang

I don't know at the moment. But you are almost done - keep patiance.

Maybe SWIG expert Johan could know?

Jan

Hello,
I followed the instructions in INSTALL and README using
  cmake .
  make install
in directory
 /home/dang1032170/Work/FEniCS/src/serial-meshes
I could complete the installation:

DOLFIN has now been installed in
    /home/dang1032170/Work/FEniCS
and the demo programs have been installed in
    /home/dang1032170/Work/FEniCS/share/dolfin/demo
Before rushing off to try the demos, don't forget to update your
environment variables. This can be done easily using the helper file
'dolfin.conf' which sets the appropriate variables (for users of the
Bash shell).
To update your environment variables, run the following command:
    source /home/dang1032170/Work/FEniCS/share/dolfin/dolfin.conf
For future reference, we recommend that you add this command to your
configuration (.bashrc, .profile or similar).

I compiled a demo in /Work/FEniCS/share/dolfin/demo/pde/poisson/cpp
cmake . (succeeded)
make (with following error)

That seems like problem with finding boost library when linking
executable. You need to have set LD_LIBRARY_PATH with all appropriate
dependencies. Try
  ldd /home/dang1032170/Work/FEniCS/lib/libdolfin.so
to check if all dependencies are found.

Paths to all libraries which are 'not found' have to be added to
LD_LIBRARY_PATH environment variable when linking program using dolfin.
I don't how did you install these libraries and what is a default way
to set paths in your system. Perhaps some paths can be set by module
package and some must be set manually. For example I add
  module load scientific boost petsc armadillo
  module unload numpy
  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/fenics/fenics-1.1.0/lib:~/fenics/fenics-1.1.0/lib/vtk-5.8
to the end of my fenics.conf to adjust paths.

But make sure that your fenics.conf contains everything from your
dolfin.conf as you finished installation of FEniCS by dorsal_build in
dolfin dir instead of dorsal.sh so fenics.conf was not generated.

Maybe you also need to set BOOST_DIR. You may find all paths manually
or use the ones from src/serial-meshes/dorsal_build_dir/CMakeCache.txt

Thanks Jan Blechta, that solved my question.

Hello,
It worked well on the python version with two files demo_serial-meshes_2.py and demo_serial-meshes.py
Then, I revised the content of poisson demo to test the parallel computing but I got some errors (see below).
Can you please help me?

Try moving
 parameters["pretend_one_process"] = true;
to the beginning to tell DOLFIN to initialize all objects
non-distributed.

Jan

Dear Jan,
It worked. However, when we set parameters["pretend_one_process"] = true at the beginning, we do not create parallel mesh, function space and functions but they are created multiple times. How to fix it?
Thanks,
Best regards,
Dang

I don't understand. I thought you wanted to make multiple serial
meshes, function spaces, ... Could you write shortly what do you want
to do?

Jan

Dear Jan,
In fact, I would like to solve multiple linear systems using the same mesh, function space,...
Here is a simple example where I solve 2 linear systems using some common information (mesh, function space,..). So, I want to create the common information by just one process and one time. However, when I set parameters["pretend_one_process"]=true at the beginning, the common information was created multiple times by process 0 (if I understood correctly?)
Thanks,
Best regards,
Dang

// COMMON INFORMATION
  // Is it possible to create this information one time by 1 process?

    UnitSquareMesh mesh(32, 32);
    Poisson::FunctionSpace V(mesh);
    // Define boundary condition
    Constant u0(0.0);
    DirichletBoundary boundary;
    DirichletBC bc(V, u0, boundary);
   // Define variational forms
    Poisson::BilinearForm a(V, V);
    Poisson::LinearForm L(V);
    Function u1(V);
    Function u2(V);
    int process_number = dolfin::MPI().process_number();
    int num_processes = dolfin::MPI().num_processes();
// MANAGING 2 LINEAR SYSTEMS PARALLELY
  if (process_number == 0) // solve system 1 with process 0
  {

     Source f;
     dUdN g;

     L.g = g;
     // Compute solution
     solve(a == L, u1, bc);

If you create Mesh when running in parallel mesh is partitioned and
each process holds some piece of underlying physical mesh. Same holds
also for objects arising from Mesh, i.e. FunctionSpace, Function, ...

If you set pretend_one_process each process does think it is run in
serial hence it does not partition mesh. Therefore each process (you
give it such an instruction) creates its own non-partitioned mesh. If
you do

parameters["pretend_one_process"] = true;
UnitSquareMesh mesh(32, 32);

every proccess creates its own serial mesh (they will be same). If you
do

if (process_number == 0)
{
  parameters["pretend_one_process"] = true;
  UnitSquareMesh mesh(32, 32);
}

Then only process 0 creates serial mesh and you could transfer it by
file or by MPI to other processes. This would be quite easy in python
where you just pickle Mesh object, send it by mpi4py and unpickle. I
don't know how to do that in C++. Or you can write mesh to file and
read it by other processes. But note that first option when mesh is
created by each proccess is probably preferable as it would have no
time advantage to create mesh by only one process and let other
processes waiting. Similiar considerations are valid for other DOLFIN
objects.

It seems for me that your parallel tasks are in no way coupled. You
should just then run many serial tasks. I don't see the point of
running them through MPI.

Jan

Dear Jan,
It seems that I have to use OpenMP instead. I knew that parameters["num_threads"]=num_threads can manage different parts of the mesh but it is not my case. I want to use a 'full' OpenMPI like pure C++. I encountered segmentation faut error with follwoing code.
  omp_set_num_threads(2);
  # pragma omp parallel
  {
     // Let dolfin believe that there is only one process
     parameters["pretend_one_process"] = true;
     Source f;
     dUdN g;
     L.f = f;
     L.g = g;
     // Compute solution
     solve(a == L, u1, bc);
     parameters["pretend_one_process"] = false;
  }

  # pragma omp parallel
  {
     // Let dolfin believe that there is only one process
    parameters["pretend_one_process"] = true;
    Constant zero(0);
    L.f = zero;
    L.g = zero;
    // Compute solution
    solve(a == L, u2, bc);
    parameters["pretend_one_process"] = false;
  }
Can you please give me some suggestions to solve this problem?
Thanks a lot,
Best regards,
Dang

Dang, still I don't see the point of doing some parallel computations
if you have many uncoupled problems. Simply do many serial computations.

You don't need pretend_one_process functionality when running without
MPI parallelization. It has no meaning.

Regarding OpenMP, I'm not sure if DOLFIN can be used with explicit
OpenMP statements. Anders probably would know.

Dear Jan.
I have to find another solution. In fact, I need to solve some linear systems at each time step. After each time step, the data should be summarized once. So, serial computations are not very suitable in this case.
Thanks a lot for your help,
Best regards,
Dang

Dear Jan,
I am using your serial computations for another problem. Unfortunately, I encountered an error related to PETScMatrix. My code is following:

 // Create mesh and function space
 UnitSquareMesh mesh(500, 500);
 Poisson::FunctionSpace V(mesh);

 // Define variational forms
 Poisson::BilinearForm a(V, V);

 PETScMatrix M;
 assemble(M,a);

 std::vector<dolfin::la_index> columns(2);
 std::vector<double> values(2);
 dolfin::la_index master_row = 0;

 columns[0]=1;
 columns[0]=10;
 values[0]=10.0;
 values[0]=10.0;

 M.set(values.data(), 1, &master_row, columns.size(), columns.data());
 M.apply("add");

Here it fails because PETScMatrix M does not have entry (0, 10).
You need to create custom sparsity pattern which would include all
entries you need. Then you create PETScMatrix out of this pattern,
assemble and set your additional values.

This does not apply to your situation as keep_diagonal assembler option
helps to keep diagonal entries in sparsity pattern. (0, 10) is
off-diagonal.

Dear Jan,
Thanks a lot for your quick response. In fact, my work is further than that. I need to write a method myself to impose one kind of boundary conditions, like PeriodicBC, in which I have to interact a lot with the PETSc matrices. It worked well with the old version of FENICS. Now, I would like to use serial computations to speed up my code. Obviously, it is not convenient to create an additional matrix at each task.
I looked at the periodic demo. It works perfectly. How can you do that without error?
Best regards,
Dang

You don't need to do that. Create one matrix but with sparsity pattern
having all entries you need. Or use dense matrices.

I can't see how periodic demo is related to this problem. In demo there
is no fiddling with matrix entries.

Jan

Dear Jan,
I will describle more details. In order to apply the periodic BCs to a matrix A, we need a dof_pair to store the master row and slave row. Here is a small part of the modified code I am using
   std::vector<dolfin::uint> columns;
   std::vector<double> values;
   dolfin::uint master_row;
   dolfin::uint slave_row;
   dolfin::uint num_dof_pairs = dof_pairs.size();
   for (dolfin::uint i=0;i<num_dof_pairs;i++)
   {
     //int num_loops = 1;
     master_row = dof_pairs[i].first;
     slave_row = dof_pairs[i].second;
     if (master_row<INT_MAX and slave_row<INT_MAX)
     {

 // take slave_row
 A.getrow(slave_row, columns, values);

 // add slave_row to master_row.
 A.add(&values[0], 1, &master_row, columns.size(), &columns[0]);
 A.apply("add");

 // zero out slave_row
 A.zero(1, &slave_row);

 //set {1.0,-1.0} to 2 columns {slave_row, master_row}
 dolfin::uint cols[2];
 double vals[2] = {1.0,-1.0};
 const dolfin::uint row = dof_pairs[i].second;
 cols[0] = slave_row;
 cols[1] = master_row;
 A.set(vals, 1, &row, 2, cols);
 A.apply("insert");
     }
   }
When I run this code in new version of Fenics, I usually encountered the error.
Hope this is clear.
Dang

Yes, this is clear. And as I said you need to build custom sparsity
pattern to avoid these PETSc errors.

I guess that in older versions you were enabled to write to matrix
entries which were not preallocated but this was forbidden because of
major performance issues.

Dear Jan,
I found a temporary solution here https://answers.launchpad.net/dolfin/+question/212407
 PETScMatrix& petsc_A = A.down_cast<PETScMatrix>();
 MatSetOption(*petsc_A.mat(), MAT_NEW_NONZERO_ALLOCATION_ERR, PETSC_FALSE);

You might want to look into development version of DOLFIN if you don't
need serial-meshes functionality. I think there has been done much work
since 1.1.0 branch on which is serial-meshes branch based.
