How to install deal.II

Deal.II is an open Finite Element Method (FEM) code. For detailed description of the code and tutorials, you can refer to their offical website http://www.dealii.org/. Here we explain how to install it on the Sherlock cluster.

System Requirements

The installation of Deal.II requires cmake 3.2 and up, openmpi/1.10.2/gcc and gcc/4.8.1. They have been pre-installed as modules on the cluster, to load them, you can type the following commands on your terminal. 

module load cmake/3.2.2
module load gcc/4.8.1
module load openmpi/1.10.2/gcc

Or you can paste the above three lines into your ~/.bashrc file, and type 

source ~/.bashrc

Setup

Assuming you want to install the package in the home directory of group's shared space, you can firstly go to the folder by typing 

cd /shared/PI/caiwei

From there, you can directly clone the package from Github. 

git clone https://github.com/dealii/candi

Now you should have a folder called candi. The next step is to go into the folder and update the following two configuration files candi.cfg and dealii.package. 

cd /shared/PI/caiwei/candi
wget -O candi.cfg http://micro.stanford.edu/mediawiki/images/1/1e/Candi.cfg.txt
cd /shared/PI/caiwei/candi/deal.II-toolchain/packages
wget -O dealii.package http://micro.stanford.edu/mediawiki/images/a/aa/Dealii.package.txt

Notice in candi.cfg, there is one line that specifies the installation path, 

PREFIX_PATH=/share/PI/caiwei/dealii/

This needs to be modified if you intend to install the package in other places.

Installation

The installation is straight forward, but it may take up to 3 hours. To make sure it is not killed by the scheduler, you may submit a device allocation request for a relatively long time. 

sdev -t 4:00:00 -p mc

When you get the node, the following automated script can guide you through the installation process. 

cd /shared/PI/caiwei/candi
./candi.sh --platform=deal.II-toolchain/platforms/supported/centos7.platform

The program starts with a couple of checks, where only requires you to press the Enter button several times. trilinos https://trilinos.org/
