Ada:Batch Job Examples

Job File Examples

Several examples of LSF job files for Ada are listed below. For translating other job files, the Batch Job Translation Guide provides some reference.

NOTE: Job examples are NOT lists of commands, but are a template of the contents of a job file. These examples should be pasted into a text editor and submitted as a job to be tested, not entered as commands line by line.

Example Job 1: A serial job

##NECESSARY JOB SPECIFICATIONS
#BSUB -J ExampleJob1         #Set the job name to "ExampleJob1"
#BSUB -L /bin/bash           #Uses the bash login shell to initialize the job's execution environment.
#BSUB -W 2:00                #Set the wall clock limit to 2hr
#BSUB -n 1                   #Request 1 core
#BSUB -R "span[ptile=1]"     #Request 1 core per node.
#BSUB -R "rusage[mem=5000]"  #Request 5000MB per process (CPU) for the job
#BSUB -M 5000                #Set the per process enforceable memory limit to 5000MB.
#BSUB -o Example1Out.%J      #Send stdout and stderr to "Example1Out.[jobID]"

##OPTIONAL JOB SPECIFICATIONS
#BSUB -P 123456              #Set billing account to 123456

##OPTIONAL JOB SPECIFICATIONS
#BSUB -P 123456              #Set billing account to 123456
#BSUB -u email_address       #Send all emails to email_address
#BSUB -B -N                  #Send email on job begin (-B) and end (-N)

Example Job 4: A serial GPU job

##NECESSARY JOB SPECIFICATIONS
#BSUB -J ExampleJob4         #Set the job name to "ExampleJob4"
#BSUB -L /bin/bash           #Uses the bash login shell to initialize the job's execution environment.
#BSUB -W 2:00                #Set the wall clock limit to 2hr
#BSUB -n 1                   #Request 1 core
#BSUB -R "span[ptile=1]"     #Request 1 core per node.
#BSUB -R "rusage[mem=2560]"  #Request 2560MB per process (CPU) for the job
#BSUB -M 2560                #Set the per process enforceable memory limit to 2560MB.
#BSUB -o Example4Out.%J      #Send stdout and stderr to "Example4Out.[jobID]"
#BSUB -R "select[gpu]"       #Request a node with a GPU

##OPTIONAL JOB SPECIFICATIONS
#BSUB -P 123456              #Set billing account to 123456
#BSUB -u email_address       #Send all emails to email_address
#BSUB -B -N                  #Send email on job begin (-B) and end (-N)

#First Executable Line

It is possible to request a whole GPU node by adding the following lines to optional job specifications:

#BSUB -x
#BSUB -R "select[gpu]" 

Please note that exclusive node use will also require more SUs.

Example Job 5: A serial job with queue specification

##NECESSARY JOB SPECIFICATIONS
#BSUB -J ExampleJob5         #Set the job name to "ExampleJob5"
#BSUB -L /bin/bash           #Uses the bash login shell to initialize the job's execution environment.
#BSUB -W 2:00                #Set the wall clock limit to 2hr
#BSUB -n 1                   #Request 1 core
#BSUB -R "span[ptile=1]"     #Request 1 core per node.
#BSUB -R "rusage[mem=5000]"  #Request 5000MB per process (CPU) for the job
#BSUB -M 5000                #Set the per process enforceable memory limit to 5000MB.
#BSUB -o Example5Out.%J      #Send stdout and stderr to "Example5Out.[jobID]"

##OPTIONAL JOB SPECIFICATIONS
#BSUB -P 123456              #Set billing account to 123456
#BSUB -u email_address       #Send all emails to email_address
#BSUB -B -N                  #Send email on job begin (-B) and end (-N)
#BSUB -q sn_short            #Send job to the sn_short node, which has one hour max walltime and is limited to single node jobs
