This is your problem: it should be something like drwxrwxrwt. It might depend on the distribution, f.e. the following show this to be a bug: https://bugzilla.redhat.com/show_bug.cgi?id=533897 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=317329 and surely you can find some more on the subject with your favorite search engine. Another source could be a paranoid sysadmin who has changed the default (most likely correct) setting the distribution came with - not only OpenMPI but any application using shmem would be affected..
