Py-ORBIT code moved to python 3. See PyORBIT3.

Build

Py-ORBIT Installation

Installation procedure requires building from source. All installation steps happen in command line (terminal).

1. Installing required libraries

Ubuntu (and other distributions using apt-get: Debian, Mint etc)

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get install python-dev libmpich-dev mpich  zlib1g-dev libfftw3-dev

RedHat (and other distributions using yum: Fedora, CentOS etc)

sudo yum update
sudo yum group install "Development Tools"
sudo yum install python-devel mpich mpich-devel zlib-devel fftw-devel

The latest linux distributions are phasing out python 2. Some modifications to package names might be needed. For example: CentOS 8 (RedHat 8) needs you to replace python-devel with python2-devel and add python2 to your package list in above yum command.

Mac

We recommend to use MacPorts.

Sync with package repository

sudo port -v selfupdate

After syncing run:

sudo port install fftw-3 mpich

Select mpich to enable mpicc

sudo port select mpi mpich-mp-fortran

The latest versions of Mac OS (macOS Mojave) don't include python 2 installed by default. In this situation install it from MacPorts as well:

sudo port install python27
sudo port select --set python python27

Building the whole environment from source

If you don't want to use standard libraries supplied by your distribution, you can build the whole environment from scratch. It is also possible to do this without having a root account. The process is described in detail here.

2. Clone the source code

git clone https://github.com/PyORBIT-Collaboration/py-orbit.git

Your source is now in the py-orbit directory.

3. Setup environment variables

setupEnevironment.sh will try to figure out all paths. This should be sufficient for common Linux distributions. If you built the environment from source, use customEnvironment.sh instead.

cd py-orbit
source setupEnvironment.sh

4. Build the code

make clean
make

If make failed, it usually means that some of the libraries aren't set up properly.

Running Examples

Setup the environment variables (needs to be done once per teminal session). If you built the environment from source, use customEnvironment.sh instead. Alternatively you can place source <path-to-pyORBIT-installation>/setupEnvironment.sh in your .bashrc.

source setupEnvironment.sh
cd examples/AccLattice_Tests
./START.sh lattice_test.py 2

This will launch lattice_test example on two MPI nodes. Other examples are availabale in Examples repository.

Structure

./src - source code for the core ORBIT C++ classes, including wrappers, etc.

./py - python modules and wrapper classes for the core ORBIT classes.

./ext - source code for external modules. Compilations of this code should be placed into ./lib.

./lib - .so shared libraries to be used under pyORBIT interpreter.

./examples - pyORBIT examples.

./conf - configuration information.

./bin - pyORBIT executables.
