Dear Javier
I had the same problem on our cluster since by default the home
directory was the NSF server (master node).
You should be able to write on each node. In our case the /local/
directory is mounted on each node
therefore choosing the outdir as /local/javier.... should
solve your problem.
best regards
cyrille
