Use of custom libraries

If you have custom libraries, make sure that they are either system wide installed on the distributed systems, or to specify LD_LIBRARY_PATH in the environment settings of the dispatcher. Note: The dispatchers will not be executing under your normal login environment! This means that if you do anything special in your $\sim$/.bashrc (or similar) you will not have the same environment for the job.

It is possible that LD_LIBRARY_PATH does not get set properly when specified in the environment settings of the dispatcher due to security reasons. If this is the case, a simple workaround is to create a wrapper script which sets LD_LIBRARY_PATH and then executes the actual dispatcher. For example, to do this for webots, create a script at ~/bin/webots-runner:

And specify $HOME/bin/webots-runner in the webotsPath dispatcher setting of the webots dispatcher (in the job file).
