Hello David, 

With the help of some people at our Campus Cluster, and following your suggestions, I was able to install Firedrake successfully (letting it build it's own PETSc) with the following configure options . 

export PETSC_CONFIGURE_OPTIONS="--download-eigen=/projects/meca/shared_resources/firedrake/src/eigen-3.3.3.tgz --download-fblaslapack --with-shared-libraries=1 --with-fortran-bindings=0 --download-chaco --download-metis --download-parmetis --download-scalapack --download-hypre --download-mumps --with-zlib --download-netcdf --download-hdf5 --download-pnetcdf --download-exodusii"

Does this seem right ?

I tried running the tests, and several examples that I had from FEniCS and with some changes to the code, all of them run pretty much successfully. However when I try to use MPI in order to run the calculations in parallel I get the following error... 

python3: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory
python3: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory

Would you happen to guess what could be the problem here, or could point out to a resource for debugging this ? 

Thanks for the help.

Hello David,

Thanks for the prompt response. I really appreciate your help on this. 

Since the cluster does not let firedrake build it's own PETSc with the correct configuration I decided to do the following: 

1. Build a docker image (docker://bhaveshshrimali/firedrakestable2) with firedrake installed (and hopefully stable). I tested the installed firedrake using "make alltest".. It does seem to pass a lot of them (if I understand correctly, F stands for a failed test, right?) with some exceptions. However when it tests regression/octahedral_hemisphere.py, it seems to fail here (it does warn that 'cannot create build.log': Permission denied): 

tests/regression/test_octahedral_hemisphere.py ....Makefile:60: recipe for target 'test' failed 
make: *** [test] Killed

Is there a way to debug what happened here. Note that up until this point everything is on my local machine. 

2. Since there is no direct way to run the image using Singularity on our cluster, I first built a singularity image by pulling the above image from DockerHub on my local machine and then just copied the '.simg' file to a folder on Cluster. There seem to be some issues running the file there (I do not understand if it is solely due to file/folder permissions) ...

A process has executed an operation involving a call to the
"fork()" system call to create a child process.  Open MPI is currently
operating in a condition that could result in memory corruption or
other system errors; your job may hang, crash, or produce silent
data corruption.  The use of fork() (or system() or other calls that
create child processes) is strongly discouraged.

The process that invoked fork was:

  Local host:          [[0,1],0] (PID 756)

If you are *absolutely sure* that your application will successfully
and correctly survive a call to fork(), you may disable this warning
by setting the mpi_warn_on_fork MCA parameter to 0.

3. Is there an exisiting singularity image with firedrake installed on SingularityHub to your knowledge ? If so, I can directly try doing singularity pull shub://... ? 

4. I also tried changing the file/folder permissions for different folders on the firedrake directory, and tried running the Helmholtz example through command line, but it fails too...

Lastly I tried updating firedrake inside the singularity container, but that failed. I am attaching the firedrake-update.log file here. Please let me know if anthing else is needed  

Any help or references on debugging through the above will be appreciated. 
Thanks again

Dear Bhavesh,

 

There are a few things going on here that are problematic.

 

The first is around PETSc. While it is often a good idea on a cluster to build PETSc separately from Firedrake, the PETSc installed on the cluster is very unlikely to have the right configuration settings for us, so you do need to build your own. You probably want to use the Firedrake PETSc version (https://github.com/firedrakeproject/petsc) which is known to be compatible with the petsc4py used in Firedrake. If building PETSc yourself then you need to specify the right configure options, which you can obtain by running:

 

python3 firedrake-install --show-petsc-configure-options

 

Alternatively you could just let firedrake-install build PETSc for you. This might be easier.

Subject: [firedrake] Firedrake Installation on Cluster

 

Hello,

 

I have been trying to install firedrake on our campus cluster, however I’ve had little success so far. I am not from a CS background so mostly have been googling stuff and trying different things. I am trying to make use of the modules available on our cluster, and use the PETSc already installed on the cluster.

 

 

I assume the following environment variables were advised by the cluster admins. If they were obtained from the internet they are almost certainly wrong:

 

              export I_MPI_CC=gcc

export I_MPI_CXX=g++

export I_MPI_F90=gfortran

export I_MPI_FC="$I_MPI_F90"

export I_MPI_F77="$I_MPI_F90"

 

These export commands don’t do what you think. Each one is overwriting the previous one, they don’t accumulate. This is also not the correct set of PETSc configure options for Firedrake, for that please see the command given above. Finally, setting petsc configure options doesn’t actually help unless you are building your own PETSc.

 

export PETSC_CONFIGURE_OPTIONS=--download-fblaslapack 

export PETSC_CONFIGURE_OPTIONS=--download-scalapack 

export PETSC_CONFIGURE_OPTIONS=--download-mumps 

export PETSC_CONFIGURE_OPTIONS=--download-superlu_dist 

export PETSC_CONFIGURE_OPTIONS=--download-hypre

curl -O https://raw.githubusercontent.com/firedrakeproject/firedrake/master/scripts/firedrake-install

 

You almost certainly do not want --honour-pythonpath here. It is almost always better to unset the PYTHONPATH environment variable. It is very unlikely that you actually want external packages to be included in the Firedrake Python venv.

 

python3 firedrake-install --no-package-manager --honour-pythonpath --honour-petsc-dir

 

This throws exception at the following point (Also attached separately as firedrakeErrortxt)

The complete log file is also attached along with this email.

 

Please let me know if you can be of some help, as I have received little-to-no help from the people managing the cluster. Also let me know if this is due to an error on my side while running the installer.

 

Thank you
