Julia is a high-level general-purpose dynamic programming language. Julia uses multiple dispatch as a paradigm, making it easy to express many object-oriented and functional programming patterns. The standard library provides asynchronous I/O, process control, logging, profiling, a package manager, and more.
The currently installed version is 1.0.1 on the environment hpc-env/6.4.
The currently installed versions of Julia are
on environment hpc-env/8.3:
on environment hpc-env/6.4:
If you want to find out more about Julia on the HPC Cluster, you can use the command
module spider Julia
This will show you basic informations e.g. a short description and the currently installed version.
To load the desired version, you must load the module as well as the environment:
module load hpc-env/6.4 module load Julia
Julia has a built in package manager.
You can start the package manager Pkg by starting Julia and typing the closed square bracket: ]
$ julia julia> ] (v1.0) pkg>
The Terminal will change color and will switch from julia> to (v1.0) pkg>
Now every command you type in controlls Pkg. You can add a package by using the add command:
add example example2 # you can add multiple packages at once
The packages will be installed into your $HOME directory at ~/.julia/packages
The same applies to removing packages with the rm command and updating packages with update:
rm example update example2
Within Pkg, you can type in ? to get an overview about the commands available.
Adding and using GR
For Julia, you can install GR, a universal framework for cross-platform visualization applications.
Before doing that, you must have established an SSH connection with X11 forwarding enabled. This can be done by adding the option -X to our SSH connection:
ssh firstname.lastname@example.org -X
Now, you can follow the steps shown above at the section Adding packages to add GR:
julia> ] (v1.0) pkg> add GR
Now you can return to Julia (CTRL + C) and start using GR and maybe add a testing sequence to prove that everything works fine:
julia> using GR julia> histogram(randn(10000))
Now you should see a histogram popping up.
