Running job monitor

en construction

under construction

A running job can be monitored/interrogated with a local utility called

u.job-monitor

There a 2 ways to activate this utility

• at job submission time:
  ord_soumet ....  -prolog jobmonitor ....
• with an explicit command in the job itself
  u.job-monitor &

caveat: in the case of an MPI job the only node that will be monitored is node 0 (primary node)

the job monitor uses 3 files found in directory $HOME/top_in_batch  for each monitored job

• jobname_node_jobid.top
  refreshed every 10 seconds with the output of a top command for processes belonging to the user
• jobname_node_jobid.cmd
  if the user writes a line in this file then
  • this line is executed on the primary node
  • the output (stdout and stderr) of said command is appended to the jobname_node_jobid.out file
    
  • the jobname_node_jobid.cmd file is erased and re-created
• jobname_node_jobid.out
  • the output of the command from the jobname_node_jobid.cmd file

node will be replaced by the host name of the primary node of the job

jobid will be replaced by the PBS job id of said job

jobname will be replaced by the job name
