• no write permission to own $HOME : rarely happens at first login; just logout and login again
• can't share data/programs in $HOME with other users: it's usually way better to use another storage to share data, but if you really need it, ask admins to relax permissions on your home
• connection refused error but my user have just been given access: you have to wait till after 7.00am of the following day, when a script updates access lists and accounting
• An ORTE daemon has unexpectedly failed after launch error on multi-node mpi jobs: try using srun instead of mpirun to launch the job step
