First version of WLCG Worker Node Environment scripts


1 The wlcg-wn-env-{pbs,torque} packages consists of a set of scripts to set up
2 the $JOBFEATURES file. This file is generated by the the prologue.user script
3 and contains the following information:
4 jobstart=<job start time>
5 cpu_limit=<maximum CPU limit available, in seconds>
6 wall_limit=<maximum walltime limit available, in seconds>
7 A job can calculate the remaining wall time doing
8 now() - $jobstart + $wall_limit

11 The purpose of each of the files in this packages is:
12 - prologue.user : set up the $JOBFEATURES file
13 - epilogue.user : clean up the $JOBFEATURES file
14 - wlcg-wn-env.conf : configuration file
15 - wlcg-wn-env.sh : set the environment variable JOBFEATURES
16
17 The wlcg-wn-env.conf can be used to change the default location of the
18 $JOBFEATURES file. If this config file is missing the scripts default to
19 ${TMPDIR:-/tmp}/jobfeatures.${PBS_JOBID}
20
21 There is no wlcg-wn-env.csh script as the JOBFEATURES environment variable
22 is inherited by from the PBS wrapper scripts, which are bash-based.

25 The only difference between the wlcg-wn-env-pbs and wlcg-wn-env-torque packages
26 is the location of the 'mom_priv' directory. For older version of the PBS/Torque
27 client (up to v2.3) the mom_priv directory was found under
28 /var/spool/pbs/mom_priv
29 With the EPEL packaged version of the Torque 2.5 client this was changed to
30 /var/torque/mom_priv.
