Since I'm estimating that your knowledge of the unix system is very limited so far, I warn you to just delete any old unused file you can grab. Your request reminds me - at my - long time past windows times, where things had to be cleanup regularly, in order to maintain a roughly usable OS.

One should be familiar what can be files can deleted and what better not to touch. If not and if the deletions are done with root privileges, you can quite quickly render your system unusable.

So my advice: Before the learning of the knowledge how to delete is the learning of the knowledge what to delete.

So if you want help, specify your request with more details:
  • What exactly do you want to achieve?
  • What files do you want to delete?
  • What is your environment(OS, Version)?

ompi-clean

orte-clean(1)							     Open MPI							     orte-clean(1)

NAME

       orte-clean - Cleans up any stale processes and files leftover from Open MPI jobs.

SYNOPSIS

       orte-clean [--verbose]
       mpirun --pernode [--host | --hostfile file] orte-clean [--verbose]

OPTIONS

       [-v | --verbose] This argument will run the command in verbose mode and print out the universes that are getting cleaned up as well as pro-
       cesses that are being killed.

DESCRIPTION

       orte-clean attempts to clean up any processes and files left over from Open MPI jobs that were run in the past as  well	as  any  currently
       running jobs.  This includes OMPI infrastructure and helper commands, any processes that were spawned as part of the job, and any temporary
       files.  orte-clean will only act upon processes and files that belong to the user running the orte-clean command.  If run as root, it  will
       kill off processes belonging to any users.

       When run from the command line, orte-clean will attempt to clean up the local node it is run from.  When launched via mpirun, it will clean
       up the nodes selected by mpirun.

EXAMPLES

       Example 1: Clean up local node only.

       example% orte-clean

       Example 2: To clean up on a specific set of nodes specified on command line, it is recommended to use the pernode option.   This  will  run
       one orte-clean for each node.

       example% mpirun --pernode --host node1,node2,node3 orte-clean

       To clean up on a specific set of nodes from a file.

       example% mpirun --pernode --hostfile nodes_file orte-clean

       Example 3: Within a resource managed environment like N1GE, SLURM, or Torque.  The following example is from N1GE.

       First, we see that we have two nodes with two CPUs each.

       example% qsh -pe orte 4
       example% mpirun -np 4 hostname
       node1
       node1
       node2
       node2

       Clean up all the nodes in the cluster.

       example% mpirun --pernode orte-clean

       Clean up a subset of the nodes in the cluster.

       example% mpirun --pernode --host node1 orte-clean
