This error still exists in Ubuntu 18.04 LTS in August 2019, three years later. The pstree version is 23.1 On our local high performance system the pstree version is 22.20 and the error does occur frequently. As of which pstree version should the bug have been fixed?
To make a case for the importance of this bug fix I need to do the following: In parallel processing i use mpi. Unfortunately, within mpi a program cannot tell if the program was started as: "mpiexec -n 20 my_program" or serially as "my_program". By running a command line "pstree -s -l -p PID" prior to initializing the MPI world, I could distinguish the two different start up modi. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629839 Title: pstree reports "/proc/xxxx: No such file or directory" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/psmisc/+bug/1629839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
