pdcp -r -w $SLURM_NODELIST $WORK/testdir2copyinput2copy/* $LOCAL_TMPDIR

$LOCAL_TMPDIR exists - only "node" locally - on all compute nodes (see Special Filesystems for more details).
To collect individual data from several node-local locations simultaneously - similar to a MPI_Gather - one can use:

rpdcp -r -w $SLURM_NODELIST $LOCAL_TMPDIR/output2keep/* $WORK/returndir

Automatically, rpdcp will rename the data by appending the local hostname of its origin. This avoid overwriting of files with the same name.
