Installation Customization

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. A solution 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 set at SLAC for RHEL5 if you're using TCSH.

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

Also, starting with release ana-0.14.1 you can specify the location of your data directory (the equivalent of "/reg/d/psdm" at SLAC) with the environment variable SIT_PSDM_DATA.  You can also do this when you specify the DataSource with an option similar to "dir=/reg/d/ffb/amo/amoi0114/xtc", but the environment variable provides a clean method to do so "globally".

Release upgrade

When you want to upgrade to the new version of the analysis release run this from the same account that was used to install everything:
