ana-0.12.1

Built-in support for OpenMPI:

This release comes with an experimental support for the OpenMPI library. We have added the library into our release system in order to make its simple to develop portable MPI applications for ourselves as well as to make the very same process easier for our users. Please, read notes below to learn about specific requirements fo developing the MPI applications within our releases.

Developing C++ applications:

To begin using MPI in C/C++ application one should include the following header:

#include "openmpi/mpi.h"

Please, note that typical examples found in various MPI documentation portals would usually suggest to include this header as:

#include <mpi.h>

If you have an existing application which needs to be integrated into our release then you will have to modify your source code accordingly.

Known issues

If you have installed a release in a non-standard locations (rather than at /reg/g/psdm) at your site/computer then the MPI application won't be able to find certain files. That's because the installation path for the library is hard-wired into OpenMPI binaries and libraries at a time when the library is being built. This problem is explained in this OpenMPI FAQ. Asolution to this problem is to find a location where the library is installed within your release and set an environment variable OPAL_PREFIX overriding the base path. Here is how this variable could be installed at SLAC for RHEL5 inf you're using TCSH.

setenv OPAL_PREFIX /reg/g/psdm/sw/external/openmpi/1.8.1/x86_64-rhel5-gcc41-opt/

Improvements abd bug fixes in pyana:

• Fixed a bug in pyana which was causing the framework to crash in the multiprocessing mode (running an application with option -p N)

• Added support for XTC type BldEBeamV6

Other improvements:

• Fixed a bug in the command line calibration tool which was assuming a wrong default path to the calibration directory
