You let's assume you can write in the /tmp directory on all the nodes (usually you can) you can use a subdirectory of /tmp as outdir, let's say /tmp/xy-job Just set outdir='/tmp/xy-job' in the control namelist. The directory has to exist on every node. It is boring to create them by hand you can use ssh with (password-less) pubkey and some bash cycle, or you can use expect.. you could also try to use mpirun in some creative way, like mpirun -np 8 mkdir -p /tmp/xy-job but I wouldn't bet on this to work.
