Hi Daniela,

Seeing more of your code would be helpful for troubleshooting the
problem.  Please provide a chunk of code that describes how you are
inputting the cdf files and what you are distributing to the nodes. 

Also include the output of sessionInfo() from one of the nodes.
For example, if cl is your cluster then
clusterEvalQ(cl, sessionInfo())

I am also ccing the package maintainer on this response.
