CRAY XC40 Graphic Environment

Building Paraview

To build ParaView on hww machines first of all download the source package of the version to be build from http://www.paraview.org/download and extract it to your home directory.

The second step would be to create an empty build directory outside the source directory since an out of source build is the recomended way to compile ParaView.

To build ParaView certain recent dependencies have to be satisfied. For an OpenGL build these are:

• Autotools
• Cmake
• Qt 4

If you plan to build a ParaView server suitable for the Hornet compute nodes als recent versions of

• LLVM with CLang
• libclc and
• Mesa

have to be available.

All of these dependencies are installed on Hornet. Currently the following versions are available:

• m4-1.4.17
• autoconf-2.69
• automake-1.14
• libtool-2.4.2
• pkg-config-0.28
• llvm-3.4.2
• libclc-0.1.5
• Mesa-10.2.2
• Qt-4.8.6
• Cmake-3.0.2

Environment setup

To modify your environment in a way that these dependencies are usable simply source the following bash-script.

setenv-pv.sh

#!/bin/bash
#
# Setup modules #######################################
module load tools/autotools
module load tools/cmake
module unload PrgEnv-cray 
module load PrgEnv-gnu
module swap gcc/4.9.1 gcc/4.8.1
#
# LLVM ###############################################
export LD_LIBRARY_PATH=/sw/hornet/hlrs/tools/paraview/4.1.0/aux/llvm/lib:$LD_LIBRARY_PATH
export PATH=/sw/hornet/hlrs/tools/paraview/4.1.0/aux/llvm/bin:$PATH
#
# MESA ###############################################
export LD_LIBRARY_PATH=/sw/hornet/hlrs/tools/paraview/4.1.0/aux/mesa/lib:$LD_LIBRARY_PATH
#
# QT #################################################
export LD_LIBRARY_PATH=/sw/hornet/hlrs/tools/paraview/4.1.0/aux/qt/lib:$LD_LIBRARY_PATH
export PATH=/sw/hornet/hlrs/tools/paraview/4.1.0/aux/qt/bin:$PATH
#

This means copying the statements above to a file named setenv-pv.sh and executing

source setenv-pv.sh

will make your environment ready to build ParaView.

Configuration

To configure and afterwards build ParaView enter your empty build directory and execute ccmake

cd <your_build_directory>
ccmake <paraview_source_directory>
