Usage Examples
Interactive Session
Note: this example is done on a compute node, usually access would be achieved with the scheduler
[username@gpu01 ~]$ module add java/jdk/1.8.0_102 [username@gpu01 ~]$ java myJAVA.javac
Batch Job
This is running the job through the scheduler SLURM by using the command sbatch myJOB.job
#!/bin/bash #SBATCH -J openJava-single-node #SBATCH -N 1 #SBATCH --ntasks-per-node 1 #SBATCH -o %N.%j.%a.out #SBATCH -e %N.%j.%a.err #SBATCH -p compute #SBATCH --exclusive echo $SLURM_JOB_NODELIST module purge module add java/jdk1.8.0_102 export I_MPI_DEBUG=5 export I_MPI_FABRICS=shm:tmi export I_MPI_FALLBACK=no java /home/user/CODE_SAMPLES/demoJAVA
