Problem running on PBS cluster

Asked by Andres Osorio

Hello,

This time, this is a real question ;-) Alright , I have manage to configure MG5 (v 1.4.8) to submit to a PBS cluster and one of its queue. However, my jobs don't successfully run (using qstat I saw a few jobs running but quickly ended).

In return I get the following message:

Generating 10000 events with run name run_01
survey run_01
compile directory
Using random number seed offset = 33
Running Survey
Creating Jobs
Working on SubProcesses
    P0_gg_t1t1x_t1_tn1_t_bwp_wp_qq_t1x_txn1_tx_bxwm_wm_lvl
 Idle: 3 Running: 0 Finish: 0
INFO: All jobs finished

"generate_events" with error:
IOError : [Errno 2] No such file or directory: '/fisica/aosorio/madgraphWD/MadGraph5_v1_4_8_4/GenStops02/SubProcesses/P0_gg_t1t1x_t1_tn1_t_bwp_wp_qq_t1x_txn1_tx_bxwm_wm_lvl/G1/results.dat'

The log file basically shows the same error:

IOError: [Errno 2] No such file or directory: '/fisica/aosorio/madgraphWD/MadGraph5_v1_4_8_4/GenStops02/SubProcesses/P0_gg_t1t1x_t1_tn1_t_bwp_wp_qq_t1x_txn1_tx_bxwm_wm_lvl/G1/results.dat'

             cluster_mode : 1
             pythia8_path :
ignore_six_quark_processes : False
                 run_mode : 1

And certainly I don't see those SubProcesses/P0_XXX/Gx/ directories (as they do when running in local in multicore mode).

Do you have any suggestion on how can I find a solution to this problem.

Many thanks,

Andres

Hello Andres,

It sounds like your ajobN files are not run at all, if you don't even get any GN directories (the first thing the ajobN file does is a mkdir GN). Perhaps try submitting an ajobN file by hand using qsub -o log.ajob1 -e err.ajob1 -q cms -V ajob1, and check the log and err files?

Cheers,
Johan

Hi Johan,

There was a problem with the pbs server configuration. Thank you for your suggestion, that was key in debugging this issue.
Many thanks,

Andres
