Remote work in computer pool

You can log into the computers in pool in graphics mode using ssh: ssh -X psolv0XX@pool.iwr.uni-heidelberg.de Instead of XX you need your account number. After login you should change the machine you are working on: ssh -X psolv0XX@cipXX

Installation on your computer with linux

In Ubuntu or Debian you will need to install with sudo apt-get install following packages:

build-essential g++ paraview git cmake libopenmpi-dev openmpi-bin libsuperlu3-dev libx11-dev

At first download the installation script from the pool:

scp psolv0XX@pool.iwr.uni-heidelberg.de:dune-parsolve-ss15/build.sh .

Running the Bash-script build.sh with the command bash build.sh you are able to install DUNE library in version 2.3.1 and the dune-parsolve module. If you have any problems with the installation on MacOS or on Ubuntu/Debian for instance, please contact Marian Piatkowski.
