Re: [Condor-users] Executable that produce graphics (e.g. histograms)

[leo@xxxxxxxxxxxxxxxxxxxxx]

Hi JK,

I'm using the ROOT system (developed from CERN) to plot the results of my
simulation. In my working directory, I have

analysis.root - a root file (contains ntuple) (this is feed to analysis.C)
analysis.C - code that produce plot/graph out of the analysis.root file
            - this file should produce a graph and save as analysis.png
root - binary file (an executable)

To run, I just type (command line)
% root analysis.C

then, a graph pops out and is saved as analysis.png on my working directory.

But when I tried to submit it to condor, I used the following:

SUBMIT FILE:
#####################################
Universe   = vanilla
Executable = root
transfer_input_files  = root, analysis.C
transfer_files        = ALWAYS
Log        = analysis.log
Output     = analysis.out
Error      = analysis.error
should_transfer_files = YES
when_to_transfer_output = ON_EXIT
Queue
######################################

% cat analysis.error
condor_exec.exe: ROOTSYS not set. Set it before trying to run
condor_exec.exe.

So I made a shell script:

job.sh:
#################################
#! /bin/sh
export ROOTSYS=/home/soft/root51200 #ROOT install directory
export PATH=$PATH:$ROOTSYS/bin
root analysis.C
##################################

...then modified the submit file
SUBMIT FILE (modified):
#######################################
Universe   = vanilla
Executable = job.sh
transfer_input_files  = root, analysis.C
transfer_files        = ALWAYS
Log        = analysis.log
Output     = analysis.out
Error      = analysis.error
should_transfer_files = YES
when_to_transfer_output = ON_EXIT
Queue
######################################

%cat analysis.error
root: can't figure out DISPLAY, set it manually

I do not know how to continue now :(

The following is a snippet of StarterLog: I don't know if this might help.
#######################################################
9/29 22:11:30 IWD: /home/condor/condor/local.physics/execute/dir_6095
9/29 22:11:30 Output file:
/home/condor/condor/local.physics/execute/dir_6095/job.out
9/29 22:11:30 Error file:
/home/condor/condor/local.physics/execute/dir_6095/job.error
9/29 22:11:30 About to exec
/home/condor/condor/local.physics/execute/dir_6095/condor_exec.exe
########################################################
But when I try to look at the /home/condor/condor/local.physics/execute/
directory, there was nothing in there! ( the dir_6095 do not exist!)


Any help would be very much appreciated.
