This page describes how to compile your own Gadget and libraries at CHPC. Before doing anything it is recommended that you create an installation directory (e.g installations) on your /export/home/username/ directory. This will help you avoid any super user conflicts. For the rest of this walkthrough I will refer to /export/home/username/installations/ as PATHINSTALL.

• First, add these lines in your startup file .profile:

  . /etc/profile.d/modules.sh
  module load sunstudio
  module load clustertools 

These lines will help you to load openmpi and other tools that are required to compile and run Gadget.

• Compile GSL by following the following steps:
  • ./configure –prefix=/PATHINSTALL
  • make
  • make install
• Compile FFTW-2.1.5 by following these steps:
  • ./configure –prefix=/PATHINSTALL
  • make
  • make install

Note that only FFTW-2.xx can be used because version 3.xx does not work with Gadget2.
