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.

Example Job 1: A serial job with queue specification

##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
#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 queue (for single node jobs with 1 hour max walltime)

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 -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

Warning: Requesting GPU resources may cause resource conflicts between users due to hardware limitations. In order to prevent this, please request a whole 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.
