Oh, yes, that's true! I am sorry for this misunderstanding. Ok, now running the same commands on one of the computer nodes, also logged as root, I obtained the following outputs: 1. ls -lrta /dev \| grep shm drwxrwxrwt 2 root root 2340 Aug 16 23:21 shm 2. ls -lrta /dev/shm/ total 76164 drwxr-xr-x 18 root root 3680 Aug 11 13:33 .. -rw------- 1 maxjr maxjr 32 Aug 15 22:53 sem.cmx000000000000039 -rw------- 1 maxjr maxjr 32 Aug 15 22:53 sem.cmx000000000000038
