The semaphores are in: ~/.parallel/semaphores so you can symlink that to somewhere else. Or you can do: export XDG_CACHE_HOME=/somedir/with/write/access mkdir $XDG_CACHE_HOME/parallel This should create semaphores in $XDG_CACHE_HOME/parallel (but it is not tested very well). I would, however, prefer if we can find the root cause and fix it. But if you only see this sometimes it will make it harder. How is the home shared? I recall doing a fix for NFS a year ago or so, so if you are not running newest version, then try upgrading. /Ole
