Attention: Research Computing Documentation has Moved
https://docs.rc.uab.edu/


Please use the new documentation url https://docs.rc.uab.edu/ for all Research Computing documentation needs.


As a result of this move, we have deprecated use of this wiki for documentation. We are providing read-only access to the content to facilitate migration of bookmarks and to serve as an historical record. All content updates should be made at the new documentation site. The original wiki will not receive further updates.

Thank you,

The Research Computing Team

AGILE (Environment for Linear and non-linear Image reconstruction using GPU Acceleration) is an open source library for GPU accelerated reconstruction problems in medical imaging. AGILE is developed at the Institute of Medical Engineering, Gratz University of Technology. It includes reconstruction code for Magnetic Resonance Imaging and Fluorescence Tomography, and was developed and tested on Linux systems.

Using AGILE

AGILE is available as a source code bundle and requires a GPU to execute.

AGILE on Cheaha

At this time, AGILE can only be run on Cheaha by building from source and running directly on the demonstration GPU node.

Preliminary Requirements

Before getting started, please review the Software Build Considerations to help create a sane, reproducible software product.

Using or building software for the GPU on Cheaha requires that you directly log into the GPU compute node. Start an SSH session with cheaha.uabgrid.uab.edu and after you log in execute a second SSH to the GPU compute node. 

ssh cheaha-compute-1-9

Set up Build Environment

The build instructions below will assume all commands are executed from a directory dedicated to the AGILE build, after you are logged into the GPU compute node, set up your build environment. In addition to your base build environment you will need the CUDA compiler utilities. 

mkdir agile-build
cd agile-build
bash
PATH=/bin:/usr/bin; unset LD_LIBRARY_PATH
module load cuda/cuda4.0

Install Dependencies for AGILE Build

CMake

CMake is a build management tool that provides utilities to support cross platform code. The CMake project provides a 32-bit binary for Linux that you can use. The utilities only control the build process, therefore the 32-bit code CMake code should not affect the 64-bit AGILE binaries produced below. 

wget http://www.cmake.org/files/v2.8/cmake-2.8.6-Linux-i386.tar.gz
tar xvfz cmake-2.8.6-Linux-i386.tar.gz
PATH=$PATH:$PWD/cmake-2.8.6-Linux-i386/bin
Boost

Boost is a collection of peer-reviewed portable C++ libraries that are targeted for standardization. Install boost with: 

wget http://downloads.sourceforge.net/project/boost/boost/1.48.0/boost_1_48_0.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fboost%2Ffiles%2Fboost%2F1.48.0%2F&ts=1322092023&use_mirror=cdnetworks-us-2
tar xvfz boost_1_48_0.tar.gz 
cd boost_1_48_0
./bootstrap.sh --prefix=$PWD/../boost
./b2 install
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD/boost/lib
Doxygen

Doxygen is a documentation system that supports many languages and builds documentation from source code and comments embedded in the source code, helping ensure accurate API documentation. 

wget http://ftp.stack.nl/pub/users/dimitri/doxygen-1.7.5.1.src.tar.gz
tar xvfz doxygen-1.7.5.1.src.tar.gz 
cd doxygen-1.7.5.1
./configure --prefix $PWD/../doxygen
make 
make install
cd ..
export PATH=$PATH:$PWD/doxygen/bin
