Roadmap

• Everyone in CTL should have a Launchpad account and be able to compile/install the development version of FEniCS

• Release FEniCS 1.0 at/before upcoming FEniCS conference (DOLFIN seems to be the key component that needs work)
  • Update parallel implementation of DOLFIN
    • Identify critical issues in HPC performance of development version of DOLFIN
    • Aim for a reasonable performance goal (near-linear scaling up to 100 nodes for full ICNS solve).
    • Prioritize HPC performance over Function interface.
  • Update Unicorn and DOLFIN to harmonize interfaces for solvers.
    • Simplify DOLFIN (likely primarily Function interface) to match expectations (both performance and interface) of Unicorn.

Developing with Bazaar (bzr)

Getting bzr

Get the latest stable version of bzr:

wget http://launchpad.net/bzr/2.0/2.0.4/+download/bzr-2.0.4.tar.gz

Define a local installation directory:

LOCALDIR=/NOBACKUP/jjan/local

Install bzr:

tar xzvf bzr-2.0.4.tar.gz

cd bzr-2.0.4

python setup install --prefix=$LOCALDIR

Set environment variables to point to local directory (do this every time you want to use your local installation):

export PATH=$LOCALDIR/bin:$PATH

export PYTHONPATH=$LOCALDIR/lib/python2.5/site-packages

bzr is now ready for use, examples (make sure you've added a key to your Launchpad account):

bzr branch lp:unicorn

bzr branch lp:unicorn/stable

bzr push lp:unicorn

Installing development version of FEniCS

For every package in the list: ufc, ufl, instant, fiat, ffc, dolfin

Do:

bzr lp:package

cd package

Either:

scons install prefix=$LOCALDIR

or:

python setup.py install --prefix=$LOCALDIR

Setup environment (can put this in a file local.sh, and then do source local.sh):

export PATH=$LOCALDIR/bin:$PATH

export PYTHONPATH=$LOCALDIR/lib/python2.5/site-packages

export PKG_CONFIG_PATH=$LOCALDIR/lib/pkgconfig:$PKG_CONFIG_PATH

export LD_LIBRARY_PATH=$LOCALDIR/lib:$LD_LIBRARY_PATH
