###Script to launch several successive jobs on Gnome 

# In your directory, you need :
# - this script
# - the reference script for Load Leveler, containing the settings of a job (which .def to use, which executable, Load Leveler settings...).
 

#!/bin/bash

##### MODIFY THIS :  
n=3  #total number of jobs 
ref='launch_128_96_64_ref' #name of the reference script 


#Following commands are specific to Load Leveler : change them if you use another batch scheduling system
ini_dir='$LOADL_STEP_INITDIR'           # Absolute path to the submission directory, as named in the reference script 
run_dir='$LOADL_STEP_INITDIR/${tmpdir}' #Generic absolute path to the run directory, as named in the reference script (eg. job_name.job_id etc...)

sub_cmd=llsubmit                        #command to submit a job
