New page

__TOC__

==Application Details==

* Description: Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented,[14] and specifically designed to have as few implementation dependencies as possible. I
* Version: 6.5.14, 7.5.18 and 8.0.61
* Modules: java/jdk1.7.0_80 and java/jdk1.8.0_102
* Licence: Free, but owned by Oracle

==Usage Examples==
{|
|style="width:5%; border-width: 0" | [[File:icon_tick.png]]
|style="width:95%; border-width: 0" | Because Java is byte compiled and then run by a runtime program it requires the module to be loaded as well in a SLURM script. This is not the case with a standalone compiled program like from C/C++/Fortran source.

===Interactive Session===

'''Note''': this example is done on a compute node, usually access would be achieved with the scheduler

<pre style="background-color: black; color: white; border: 2px solid black; font-family: monospace, sans-serif;">

[username@gpu01 ~]$ module load java/jdk/1.8.0_102
[username@gpu01 ~]$ java myJAVA.javac

</pre>

===Non-interactive Session===

This is running the job through the scheduler '''SLURM''' by using the command ''sbatch myJOB.job''

<pre style="background-color: black; color: white; border: 2px solid black; font-family: monospace, sans-serif;">
#!/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
